Garmin Edge 305 Lockup / Not Powering Up Problems

// June 12th, 2008 // Cycling, Tech

Garmin Edge 305I love my Garmin Edge 305 and love having it on my handlebars on ever ride, race and commute. It gives me all the standard cyclocomputer data like speed, distance, etc. but adds on a lot of extras including altitude, cadence, heart rate, etc.

But twice now (the first being here), I’ve had to do my Tuesday night group ride without because it wouldn’t power up. That first time, it actually did power up, though only to the splash screen, where it would tell me the battery was drained.

This past Tuesday, pressing the power button didn’t even get me that far. Plugging it in to either the computer’s USB or the wall wart power did nothing to revive it. I did a quick search for my problem and didn’t find a solution, though I did see a few others with the same problem. A cursory look at Garmin’s site didn’t reveal an answer either. So I called their support and after being on hold for awhile, got a solution. Here’s the solution, to save other Garmin Edge 305 user’s from having to wait on hold:

Press and hold the mode and lap/reset button simultaneously for roughly 5 seconds to reset the unit. Unfortunately, there’s no queue to let you know it’s been reset, but after roughly 5 seconds, let go of that button combination and press the power button. The unit should power up now, albeit in my experience it’s going to need to go back on the charger.

The support rep I talked to from Garmin claimed that sometimes the unit will lockup after charging, which is a really strange time for the lockup IMHO, but I’ve experienced it twice now firsthand – both times, the battery was completely drained.

Here’s to hoping they fix this in a future firmware release soon. I’ll be checking Garmin’s software/download site often. I’m now in the habit of doing a quick power-up after charging and on other random occasions to make sure it’s still functioning.

I’m pretty much making this post in hopes it shows up in Google. While I didn’t do an exhaustive search, several keyword phrases never came up with the solution. So here’s hoping that my little ol’ post shows up in the search engines and helps fellow Garmin Edge 305 users out there if they too ever experience their Edge 305 not powering up.

Update: It’s 2010 as I write this, and I’m still having continued issues with batteries and bootup problems. While the trick above helps get the unit into a state of usefulness, my units have still be problematic. See my post about exchanging for a fifth unit.

    Thanks for the info!!!! I was about to throw mine against the wall tonight when it’s wouldn’t even show that it was taking a charge. Thanks to a quick Google search I had your topic read and the unit working in about 120 seconds. Thanks!!

  2. Keefer says:

    Sweet, glad I could help out. That’s exactly why I made that post to begin with. It’s nice to have confirmation that someone’s found it and made use of it.

  3. Mark says:


    I found you on google and it fixed my problem. I did a ride with out my garmin today and it drove me nuts. Great help thanks

  4. Keefer says:

    Awesome! Glad I could help out another cyclist!

  5. Linda says:

    Thank you, thank you, thank you. I did contact garmin about this problem and they emailed me to push the mode and power but that did nothing at all for this problem. Your solution worked. I have now had 4 of these units, 2 I had to send back due to the vibration shut down problem and 2 reconditioned ones that I recieved as replacements. They have ALL had this problem! Thanks again. I can have it on my ride now!

  6. Jordan says:

    Thanks for the info! Good posting- Google led me right to it. I was extremely frustrated this weekend when I couldn’t get the thing to turn on for the morning group ride. Sounds like Garmin has some issues they need to address from Linda’s post…

  7. Jesse says:

    Thank you! I unfortunately DID throw mine against the wall thinking it was dead. Thankfully, it still works! I should probably problem solve in reverse order next time…

  8. Chris says:

    A big THANKS!!! I was ticked when I could not power it on, and the USB’s would not get the unit to do anything. I was like the other posts and ready to thow it, but thanks to this post saved me some serious money!!!

  9. Keefer says:

    I’m so glad to see so many people finding this page and that it’s helping them. Thanks for all the comments!

  10. Dave says:

    Dude THANKS!!!! I was so pissed off when my Edge stopped working last night. We had just got back from a 60 mile ride, I hooked up the unit and bleep, the whole thing just shut down. I worked on it for a while, reloaded the software, cussed and then did the google search. Thanks for posting your fix, you saved me a lot of money as I was headed to the garage for a hammer.

  11. Dave says:

    Glad I found your site on Google! I had the same issue and couldn’t remember the combo (checking on my HR at work). Had a chuckle when I saw your name, one of my dogs is named Kiefer! It means pine (as in pine tree) or jaws, in German.

  12. jason says:

    You are the man!!!!I’m now happy again.

  13. Pete says:

    Thanks for posting this.
    It hasn’t worked for me yet, but if I find another solution I’ll add it here later.

  14. Pete says:

    Ha! On my edge305 I had to hit the and buttons for 10 seconds. Maybe I should learn how to read a bit better! lol
    How did I miss the word “mode” in your description?
    Thanks for the informaion!

  15. Scott says:

    Thanks man, you saved me a bunch of frustration. Worked like a charm for me. Found you on Google. Now I can ride in the morning.

  16. Ralph says:

    Thanks! Worked like a charm. Have had this problem on and off for months. usually had to let is sit a week before it would power up.

  17. Karl says:

    Terrific fix, thanks. I must admit I was the same as Pete and missed ‘mode’ in your description at first so I also grateful to him for admitting it as it made me look again!

  18. Eric says:

    Sweet! Thanks for posting this.

    I was really bummed when it wouldn’t power up this afternoon for my ride home (5 miles, 2200′ ascent). Guess I’ll have to ride it again tomorrow with my Edge to get credit for my training!

  19. Sebastien says:

    Thank you very much for this post! It was very helpful to me!

  20. DCrooksMan says:

    I tried all the Garmin recommended solutions and thought all was lost…Then I read this post and THANKS!!!!! my techno weenie whizz-bang gadget works again…(or so this is what the old school gaffers I ride with call it).



  21. Jeff says:

    Thank You!!!! I love my edge 305 and now it is back to life.

  22. Franz says:

    Thanks for posting this. I was so mad when I found my device froze and I have a huge race this weekend. Being labor day I couldn’t get support but you solved my problem.

  23. FizzyD says:

    Keefer – thanks you are a techno wizard star. out in the mountains training his week and couldn’t get my garmin to work this morning. 1 missed ride data but i’m just glad its working now!!

  24. Brandon says:

    Thanks, you saved my 305 also. I was so pissed b/c I am riding in a tour tomorrow and it would not power up!!!!

  25. Yoopdog says:

    Thanks! This glitch started in the past 6 months on my 305. My work around was to press as many keys as I could get my fingers on and after 10 minutes of random combinations I could (sometimes) get it to turn on. This glitch rendered my 305 useless for the Triple Trail Challenge (in southeast Michigan) this past weekend. I finally turned it on but the battery wasn’t charged despite being on the charger overnight.

  26. Michelle says:

    Phew! Two rides without my 305 made me realise how addicted you get to the data.
    In my case I found it wouldn’t charge via the USB so I’m now having to use the AC to charge it. I was, however, ready to use your reset method if the AC didn’t solve the problem.

    Thanks Keefer.

  27. Eugene says:

    Dude – thankx – I also called Garmin and stayed on hold for like, ever – techie guy told me to hold the Reset and Power button for 30 seconds – this did not work so I left the unit on charge for 3 days and the problem eventually cleared – unfortunately those 3 days were intensive training days so I missed out on the stats – curse you Garmin (fierce look and shaking fist) – you are my hero, I’d like to have your children ……..

  28. Guillermo says:

    Thanks a lot Keefer…!!!!

    Today that I urgently needed my garmin it didn’t power on, I tried to reset using the USB and power Charger however I couldn’t.

    Thanks a lot for your help.

    Guillermo from Mexico.

  29. Bill - Austin, TX says:

    Thanks! I’ve managed to somehow turn it on when this has happened before but this weekend it let me down big time. I needed it for a 24 hour race last weekend. I wish I had found your post on Saturday!

  30. John Mansell says:

    Thanks for the info! My 305 also would not start up after a full charge. Did a quick search and found your post. The reset worked. The battery in my unit was also completly discharged. I hope Garmin fixes this issue fast in firmware.

    Take care!

  31. ldog says:

    Thanks!!!!!!!!!My 305 wouldn’t charge on my laptop and wouldn’t do anything when connected to the battery charger so
    I googled and found this post.Excellent, I now am seeing the “battery charging in progress” on the display. Thank ou very much.

  32. Florian says:

    Thank you!
    I have the same problem, when I have ride outdoor with a temperatur of -4°C, the garmin wouldn’t anything.

    And now it’s OK

  33. Stoney says:

    You’re a legend, thanks! I was about to bin mine as I thought it was dead. Just need the snow to melt and I can get off the turbo and start using the Edge again properly!

  34. Boulderite says:

    I love the internet… Just searched for this problem, and the link here popped up. Solved the problem and I’m back on the trail. Thanks so much for posting this!!!

  35. Glennon says:

    Hey Thanks,

    I was just about to go exchange my 305 when I found your post. Thanks for taking the time to write about this issue. It was extremely helpful.

  36. Nigel says:

    Like everyone above, thanks. What a saviour.

  37. alan says:

    Thanks – had exactly this problem – could not get it to work, tried the above and bingo – genius – thanks again!

  38. Becky says:

    THANK YOU!!! That was exactly my problem and it was solved instantly. I appreciate the help!

  39. adrian says:

    thanks too – you and Mr Google. very lonely run this morning when the 305 would not power on but the next run should be fine.

  40. Dave says:

    Thank you. Dropped it on the floor today – thought it had died for ever. Did as you said and resurrected!

  41. karen says:

    Ty sooo much…I thought my watch was a goner!! It immediately came back on after hitting the lap/mode buttons… then the power button!!!

  42. markrjl says:

    Thank goodness this is easy to find through google – just saved me having to return the unit after just 3 months use. Well done for posting this solution.

  43. Adrian Bolton says:

    just happened to me, what a wondrful person you are for posting this on here, saved me having to phone garmin instead of riding my bike

  44. Thanks for the tip, i tried holding down Power + Reset + Mode & it worked. Thanks

  45. JimT says:

    Wow!!! Appreciate it I had no clue I was =about to throw mine out the window.
    What other options are out there that may be better???


  46. Wayne R says:

    Thanks for the great info. My unit didn’t respond until I added the “Mode button to the equation. Reset+mode+on got me back. I think it is terrible that this unit freezes up after charging. I also have a Garmin eTrex that I use for touring. It has been bullet proof but doesn’t have full bike feature like heart rate, cadance, etc. If Garmin is out there listening Please make a true full featured GPS unit for cyclist.

  47. Laura says:

    Awesome! Thanks for posting this. I was getting really upset and frustrated and that did the trick. I guess all computers need to be reset every once in a while but what a bummer.

  48. Richard says:

    Thanks I did not knoe why it would not start but that did the trick straight away. Thanks for posting your solution it saved me time and money :)

  49. Richard says:

    This is the second edge 305 Ive had – it cost me £65 to get Garmin to send me a new one when the first one siezed up out of warranty. The replacement seized up after only 2 months and just after setting a personal best after a ride. I did what you suggested and it worked straight away – fanatastic, thank you very much.

  50. Ole Petter says:

    Thanks.. saved me a lot of trouble. It’s up and running again. Ole Petter (Norway)

  51. Brian says:

    Thanks so much for this post… I just started having this trouble on mine. It started after the battery drain. Oh goodness, I wish I had caught it before that happened. I can’t even transfer data to my computer with mine now. I hope to find a fix for it online. Thanks again for this helpful info~

  52. Rob says:

    Thank you. Thank you! Thank you!!
    Awoke day 1 on vacation in California and found that I had to go for my first ride without my Garmin. Stuck to the Coast, so at least I didn’t get lost. But it’s not nearly as fun as taking off into the country, and knowing that the GPS will always get me home. Your fix worked, and I’m looking forward to going out tomorrow/

  53. bagg68 says:

    I’ve fought this battle for 4 years now. The above mentioned routine always has worked for me (mode + lap), but today it simply would not work at all. I could get no screen at all despite trying to recharge and press the button combo. I decided to press ‘Menu’ slightly before ‘Lap’ and held down for ten or so seconds. That did it. Weird. Also, try making sure the unit is on a tad before you power it off after a data transfer or recharge. This seems to help it remember it’s not stupid.

  54. Jayhawk923 says:

    Thanks for the post… would not power up or charge at all… Garmin website says to press “reset” for 3 seconds to unlock a locked device… this did not work. Pressing “reset” and the “Mode” button simultaneously for 5 seconds worked… Unit is now charging… thanks bunches…

  55. That Guy says:

    You’re awesome! I have an edge 500 but it will not communicate to so I ride with both on the bike. I love the 500 but I log my rides with the 305. Anyhow leaving for a ride the 305 was dead. I was bummed because I really enjoy taking part on the I’ve ride. A few rides without it and then I searched garmin 305 edge broken and it led me to your post. You’re the best. I can’t thank you enough for taking the time to help out all your fellow riders.
    Thanks again,
    That Guy

  56. Rifka says:

    My Edge 305 stopped working this a.m., when I put it on the bike prior to my 30-mile ride. When I returned home I found this link, and tried the MODE/reset 5-second hold. Eureka! it’s charging again!

  57. raphael says:

    wow! amazing. I got so used to riding with this thing I already wanted to buy another one. But now it got back to life! Thanks a lot for the post.

  58. Simo says:

    Cheers for this advice. I had already started looking for a new one.

  59. Fgbutler says:

    There may be a pattern to the lock-up as the only times my device has locked up is when I put it back on the charger after it is already fully charged.

  60. stimon says:

    Keefer, thanks for posting this quick fix. My 305 just did it’s first lockup today (right before a ride…). I didn’t get to try the fix till after. Unit reset, powered up and transferred data. I had been charging it but didn’t complete the charge before I unplugged. I wonder if that has something to do with it? Thanks again.

  61. Rich says:


    I am echoing the others here; thank you so much for posting the trick to unfreezing the Garmin 305. I am 3 weeks away from a marathon and this morning went on long run and 305 was dead in water. Reset with your information and it’s up and running again. Thank you.

  62. Rodd says:

    Had the same problem. Tried the fix and it works!! Thank you!!

    • Keefer says:

      While this is another issue I’ve had, it’s not the one we’re talking about with the lockups and not powering up. Our problem seems to have soemthign to do with the firmware not recognizing the completed charge cycle (or a request to charge an already charged unit), or something along those lines.

  63. Ben says:

    I just wanna a brief comment to thank you for posting this ! It worked right away…. I was devasted when I couldn’t ride with my Garmin ! Thanks again ! You saved my butt ! ;o)

  64. kfrank7 says:

    Amazing!!! I’m back up. Thank you sooo much for publishing this quick fix.

  65. Steve McGill says:

    Thank you- Keefer- Edge 305 reboot success!!!

  66. Cheez says:

    Two weeks away from a marathon and I was freaking out
    because my 305 died. Your reset worked – thanks a million and Happy
    New Year!

  67. PEGGY says:

    WOW! Tried the quickfix and it worked! Thank you so much! I
    KNEW there was a A WAY to RESET THIS THING! I just didn’t know it
    took two buttons for 5 or 10 seconds rather than one! Thanks so
    much! SOOOOOOO happy. . . Garmin had to go back to the charger.
    You’re so right about that part! both. . . all. thanks for posting
    this! I’m telling EVERYONE!

  68. Big ups to Keefer for revealing this trick! I was surfing for a new Edge 305 after mine didn’t boot up this morning. Fast 55 miler through the vineyards to open the season today in California’s gorgeous Napa Valley. 65 degrees! January 22! Amazing! Thanks again.

  69. Brian says:

    Keefer, thank you so much. I thought my unit was fried but this trick worked.

  70. ruth says:

    Thank you so much! I was trying to figure out how I could possible afford a new Garmin, when I read your posting, tried it – and like magic – my Garmin works again! Thanks a million!

  71. Jerry says:

    Yay! It works again. Thanks for the info.

  72. Gavin says:

    It was about to go out the window. Thanks for the info.

  73. Dave says:

    Well your page did come up on Google, thank goodness. I can’t believe they haven’t fixed this yet. This isn’t a $20 toy, it cost be big $$$

  74. Carl says:

    Thanks for the tip. This is the first time this has happened since I got the unit 2 years ago, I hope it is the last, but I am not optimistic.

  75. Mac says:

    I can’t thank you enough for posting this fix. This is the second time my Edge 305 locked up, albeit the last time it occurred was over 12 months ago. You saved me an untold amount of grief after I spent an hour reading the manual cover to cover. Thank you again for posting.

  76. BushNomad says:

    Thanks for your help, first time I have encountered problem in 2 years but searched google and found your post straight away! Now back up and ready for the next route!

    Appreciate your time, thanks again!

  77. Mark Hocutt says:

    Thanks for the help. It worked.

  78. Emile Viljoen says:

    THANKS A LOT for this tip – thought my Edge 305 has died forever, then got this on Google. Did the reset routine and all is well again!!

  79. Greg Rupert says:

    Most excellent post of troubleshooting the problem. It fixed mine and saved me from a nightmare of struggle.

  80. Rick says:

    Thanks a million- it worked easily!

  81. J.W. from the UK says:

    Thanks very much. Exactly the same problem, easily solved after reading your blog.

  82. Rick says:

    THANKS. It worked.

  83. cabanth says:

    thanks! that solved my problem as well.

  84. Kobie says:

    Happened the 1st time to me this morning before a big MTB race. Was not a happy man. Did the reset now and it worked. Thanks man!

  85. Dan Thompson says:

    The best post ever!!

  86. Yanek says:

    Many thanks to your post. I’m currently on a bike trip to Switzerland and you save my day. I’ve had this problem before but never found such a quick and efficient way to solve it.
    Good job !

  87. Roald says:

    Thanks a million. I just experienced the problem today when preparing the Marmotte I am riding tomorrow. Panic mode but thanks to your advice I can concentrate on the race again

  88. tom says:

    Many thanks. It is the 2nd time I had this problem.
    You save my wallet with this post !!!

  89. Colm says:

    Once I got it turned on, I ended up having to do a reset while it was on. Now it works. but it took some effort.

  90. Keith Farnham says:

    Just got back from my regular Sunday ride having suffered the same problem. Your article DID show up in Google, well done…and it seems to have worked, my Edge 305 is now plugged into the power and will be ready to use for my next commute. Thanks!!!

  91. Becky says:

    Thank you! I have a Garmin Forerunner that just did the same thing and would not turn on. I was glad to see your post. It wouldn’t turn on and I followed your advice and it is working now.

  92. Gary says:

    Thank you so much! Worked like a charm… I”ve heard elsewhere that otherwise to “resolve” the issue you just leave the garmin site for 2 or 3 days and then it will come back online

  93. Richard Schuster says:

    Thank you! Thank you! I thought my 305 was dead… But now it is alive again :-)

  94. waldo says:

    Glad I found this before I ordered another one. Thanks!

  95. Rome says:

    Thank you! solved my problem, superb.. I was close to purchasing a new one.

  96. John says:

    Found this on Google – and it fixed the problem. Cheers mate.

  97. Mikael Buse says:

    Thank you so much for the information!!!! I googled “Garmin edge 305 problems” and immediately found your page and now it works again. I was just about to give up and throw out my garmin !!!

  98. Jeanne says:

    Your page saved me from what i thought would be a return of my Garmin, which i just love.

    Thanks for posting this info.

  99. Jorge W says:

    Wow – mine stopped working completely after trying to upload data to the PC. Googled and found this site – Bingo! Thanks so much!

  100. Leigh says:

    Thanks so much!! This was a great help! I was able to reset mine, thanks to you sharing this info :)

  101. Warren says:

    I am doing a HUGE race this weekend and when my garmin 305 just died whilst doing garmin connect download yesterday I paniced big time – did NOTHING via on/off, not charging, not picking up with USB….Found your post and all good in 1 minute! Thanks a stack!!!

  102. Bert says:

    I just experienced today what you describe in your original post (dated 2008!) … We’re in 2012.. but I guess Garmin has by now lost interest in supporting the Edge 305! Anyway, thanks for your original post , I was clueless and about to ditch my device when a google search took me here ! My edge 305 is back in business …

  103. Tim says:

    Thanks a ton. I thought my Garmin 305 was toast. I’m glad to have it back.

  104. Mark says:

    thanks! 1st time my unit went dead. you’re info wokred.

  105. Jimmy Brown says:

    Thanks heaps ! worked like a charm :)

  106. BobbyBrown says:

    Thanks, this did the trick!

  107. Dave Knight says:

    Cool!!! My unit is a few years old and when itdied I thought it wld be a good opportunity to upgrade – then checked prices and remembered how much these little things cost. Relived that after a 5 mins search I found your advice and voila we are back in business.

  108. JP says:

    Thanks; I was already eyeballing the 405…

  109. Jason L. says:

    Thank you for this quick fix. This was the first time it happened after downloading data to PC. I still don’t know why a full recharge is required after the fix. Garmin must be addicting because so many people were still sticking with them after the problem surfaced.

  110. George says:

    Thank you! I like my old Garmin 305 running and biking and would have been bummed if I he’d to get a new unit.

  111. James says:

    You just made my day! Thanks!

  112. Maris says:

    Thanks! I’ve had this problem twice now. And I was about to get another bike computer. I’ll try your solutions when its shuts down again.

  113. Paul says:

    Thanks. It did it to me as well and your solution still works. Unfortunately, we could have hoped that in the meantime Garmin had fixed the bug :-(

  114. Steve Kearney says:

    Every user (or potential user) of the Edge 305 should be made aware of the poor battery connection problem. Garmin charges about $100 to fix this (!), but it really is a simple design fault to fix, See . I tried it and it solved that problem beautifully. Of course, the handlebar mount failure problem led to the unit detaching and smashing soon after, but Garmin won’t mention that either.

  115. lio says:


  116. Robert says:

    Thanks. Found my 305 “dead” after recharge and nothing in the manual re this problem. Your advice fixed the issue right away. On my way to Madison to preview the Ironman course and I dreaded being w/o my 305. great advice and thanks again…RB

  117. ivor says:

    THANK YOU That was exactly my problem and it was solved instantly. I appreciate the help! First time it has happened to me in 5 years.

  118. cc wong says:

    Thanks. My 305 was locked up this morning and managed to revive it using the method mentioned by you. Think this is the 2nd time in 4 years. I forgot how I revived it last time.

    My 305 battery now can’t last more than 5-6 hours. Thinking of edge 800 or Bryton’s rider.

  119. Si Green says:

    Thanks so much for the info… was preparing myself for a lengthy call to Garmin or maybe a replacement unit.
    Many thanks!!!!!

  120. max says:

    Maaaaagic Keefer!!!!

  122. Chris says:

    Thank you it worked!!!!!! Sorry your continuing to have problems, but now I can go on my long run tomorrow with my garmin.

  123. Lori S. says:

    Thank you sooo soooo soooo much!
    I thought that my garmin was toast
    until I came across your website and
    your suggestion fixed it!!!!
    You were my angel tonight!!!!

  124. Hadi says:

    Thank you very much for the fix. I left my Garmin connected to my computer and it went into hibernation for a few hours. When I woke my cpu up, my Garmin was completely dead and didn’t want to power up nor even take a charge.
    A quick Google search led me here and my Garmin is back to normal. Thanks very very much.


  125. Bill L says:

    Thank you SO much for posting this. My garmin has been acting up lately (sometimes it just won’t power on) and this fixed it exactly as advertised.


  126. David says:

    Thanks to you and google. All fixed.
    Today may have been my best ride ever but now I will never know as the Garmin died but you gave it life again. Thanks for posting


  127. Larry says:

    Keefer, as of right now, for me, this
    is the most important piece of information
    on the internet. Much thanks.

  128. Lenny says:

    Thanks! Had the same issue today..quick fix!

  129. Sendgridover says:

    Arrrghhh – how annoying, Garmin not firing up – took 3 attempts at the button combo fix but has now come back on – Many thanks

    Thanks my brother!!! Had the same problem. Just finished canoe paddling 14+ miles in Kaneohe Bay, Hawaii. Had an epic solo run and thought all my data was lost. You saved the day my man and not to mention a bit of cash. I was seriously contemplating on upgrading to an Edge 500, ___Aloha & Merry Christmas. Cheehoo!!!!

    Thanks – It was working perfect on the ride, when

    i tried to download the info nothing worked including trying to charge. After doing your reset the unit works fine again.

    Thank you for taking the time to post.

    Found you thru Google, worked for me today and I have the available battery upgrade (search eBay, it’s worth it). Second time it’s happened to me, first was before the upgrade.

    I was convinced my Garmin 305 was dead and gone – thank goodness for Google. Yours was the first thing to come up that looked like a solution and solve my problem it did and saved me having to go out and buy a new device this weekend. Many thanks

    Like everybody says, its MADDENING when it happens. When I last put it on the charger, “BATTERY CHARGING IN PROGRESS” as normal. The next morning it was dead, no “BATTERY CHARGING COMPLETE”. I tried the two button MODE/RESET (soft reset) to no avail but after the three button MODE/RESET/PWR (hard reset) it powered up with “LOW BATTERY” warning. And now it is charging normally. See Now hoping the battery is still OK.

    Thanks for the advice to reset the unit.

    It fixed my watch that would not startup.

    I found a guy onEbay that replaces batteries.
    Thought for sure mine was a goner! No less another $50 repair.
    The original one I owned, lost in an MBT race, never to be seen again.
    Bought a used one on Ebay, expecting the worst, worked fine for a number of months, then the described symptoms, tried it a few times, but did plug it in and saw on the screen, “Charging in Progress”, much to my amazement.
    Add me to the “Thanks” category!

    Thank you so much although I was looking forward to a shiny new Garmin unit at least my 305 is still working while I decide.
