    I "stored" the 305 on the charger about 3 months ago. the charger which was plugged in. When I tried to use it, I could not get it to start and it doesn't appear to be charging from either a wall plug or from my USC port

    I have the same problem. I left the Forerunner 305 plugged to the usb cradle for a while (10 hours or so), then when I tried to check if it was still charging the display was blank. Hooked it and unhooked it from the cradle and nothing happened: no sound, blank screen. It didnt turn on. I left it unplugged for one night and the day after it turned on (luckily).


    But it happened again, and I've tried the "soft" reset (holding mode and reset for 10 seconds) and it worked fine!

I have had the same problem. To fix it, I simultaneously hold down the "mode" and "reset" buttons for about 10 seconds. After releasing the buttons I power it up as normal. This has worked both times it has happened, and I got this fix from the Garmin website. My mileage totals are still in the history.

Go to Garmin website Updates & Downloads, Training Centre for Windows software version 3.4.1, click on download.

I previously deleted all saved couses on Training Centre, but don't know if this is relevant.

Hi

I have a problem with my 305 whereby the mode button stopped working so semi pulled mine apart.

If you look at the 305 from the side you can see where the rubber bit covers the buttons. The bottom of the rubber bit is attached to the rear of the forerunner - don't try to detach it - I munted mine a bit detaching it. At the top of the rubber, nearest the face you'll see a small gap. Follow the gap anti clockwise from the power button down to bottom left corner of the face near where the wrist strap pin is. Here you'll see the gap is plastic on plastic on plastic. I believe a thumbnail or similar in here and worked around carefully will let you pry the face off. I stuck my thumbnail in there and got the face to lift 1-2mm before I backed off. Note I didn't go any further than that.

For my problem by the time I had munted the rubber cover and was able to operate the mode button with a paperclip I new it was dead so didn't bother going any further as I could still use the 305 in reduced mode without mode changing.

You need a new battery. There is a small chance there is a hardware problem but about 99.9% of the time its just the battery giving up.

I have bought a new computer, windows 7. I cannot install driver for forerunner 305.


Glad to HELP YOU!

It's a well-known issue between Windows 7 and Garmin Forerunner.
Garmin company says it's a compatibility issue concerning the USB connection between the computer and the device and usually they recommend to be an Intel Chipset.
Try to download and install using the latest drivers available on their site on WIN 7 and Forerunner 305.m You have them ALL here and the USB driver was released this year and it's the last one on that list.

GOOD LUCK!

Garmin Forerunner 305 won't turn on and won't charge. Is there a fix or is this it for the device?


Look at

You can soft reset or hard reset the device. Hard reset deletes all data.

you can't. If it is getting softer and softer the speaker may be on it's way out.

See this link for a possible reason (bottom of the page).

My Garmin 305 has stopped working. It is 1 1/2


If it won't start, try connecting it to your computer and see if you can get a firmware update to turn it on. Otherwise I would send it into garmin since there aren't replaceable parts for consumers.

Garmin Foreruner 305 will not turn on or charge


I had the exact same problem and thought my beloved forerunner 305 had finally died. Try pressing the lap and mode keys simultaneously, and then power on. That may do a "soft reset." Worked for me.

Garmin Forerunner 305 usb cable won't be read


The problem is probably not with the USB cable if the GPS wont even turn on. The older firmware of the Forerunner 205 and 305 have a problem with locking up. This causes the Forerunner to look completely dead. There is a reset procedure: push the mode and reset button at the same time and then let go and hit the power on button. If it powers on that is the problem. Go to the Garmin site and load the newest rev. of firmware into the Forerunner. Fixed mine and a few friends with the same problem.

I do however have a cable problem. Sometimes my PC will come up with unrecognized USB device and my 305 wont talk to the PC, it does charge. It is the cable or dock for sure, because I have tried a different cable/dock and the 305 has no problem. This is the reason I ended up here. I hope the lock fix works for those with the above problem.
