The edge 305 unit does not answer to hard and soft reset command


Just to be sure ...

Here is the way to reset the Garmin edge :

Soft reset : hold mode and lap/reset buttons for 10 seconds
Hard reset : device should be powered down, hold start and mode buttons for 3 seconds then pulse press the lap/reset button.

After soft reset, you need to hold start button for up to 10 secs before it starts.

After hard reset, you will loose all your data, including profiles

Now if this does not work, you should check battery. Does the device charge when plugged on PC ?
If it does not, either battery is out of order or the contacts inside the device re broken. This may happen if device is used in continuous vibrating environment like mountain bike.

Changing battery or fixing contacts issue is explained there :

My 305 is 3 years old. Recently, after the device is fully charged, it works approximatlly 1 hour and then turns off. on the bike it turns of with every bump on the road. when running, trying to use one of...


Seems you cumulate several issues. If device works only one hour when charged at maximum, without bumps, then your battery is dead, because too long time discharged. You should change it.

The Bumps issue is another one, generally due to bad contacts inside device. Only way to solve is to open device, then arrange for golden contacts inside to be in closer contact or short circuit these by soldering small wires.

Garmin Edge 305 completely dead, any ideas why? It worked yesterday.


I found that switching the device on and/or off while connected to the computer can leave the screen blank, and won't give any sign of life when the ON/OFF button is pressed. In reality the device is on and the batteries will drain. Try a RESET in that case by pressing ON/OFF and MODE buttons, and briefly pressing the LAP button.

My garmin edge 305 freezes up during the ride on occasion. the distance and elevation numbers just stop changing, while I'm still riding. thanks


OK, There is a battery problem where the contacts become loose within the unit, i opened mine and followed the instructions i got on this site...MTB gurublog If you decide to do so..however if the 305 is in warranty contact garmin.com and ask for new unit... they accept the problem is widespread.

Edge 205 turning off through runs


There is a generic battery contact problem in the body of the gps, same in 305...this link will show you how to remedy it..MTBGurublog i have done it with my 305 and now do not have the shutdown anymore.... But, before you perform surgery try a full reboot... turn unit off then press mode and power together... unit will ask if you want to delete data..select yes and then manually insert all data again

Won't turn on...hear the beep, and screen works.


Exact same problem for me on the exact same day (2-sep) as well - freaky! Unit was out of battery and I charged it but that was the last time I managed to get it working - charging it now to see if it makes any diff. Actually with mine I hear the beep and the initial splash screen shows for about 1 sec and then that's it - it seems to go off again. I think it's something to do with the battery as it seems to work when connected to the charger - not a whole lot of good to me!

I think that you have got a loose connection on the battery. I had the same problem, took the top off and had a poor connection on one of the battery terminals.

Any jolt would cause it to shut down.

Should be a simple fix if you don't mind going inside!
