Opening forerunner 305

My two year old Garmin 305 shut off while in normal use. It happens when a little pressure is given on the backside. I would like to open it for an inspection. Could you tell me how to open the watch?
Thanks for your help.

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.

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!

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

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.

My Garmin forerunner 305 will not turn on.


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.

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!
