205 Forerunner Turning off


My unit tunrs itself off after a couple of minutes and also if the unit is tapped, even gently

.My forerunner started turning itself off in the middle of a run. I felt it was because I had overcharged the unit by leaving it plugged in the wall overnight. I called for support once because I couldn' t get the unit to come on, but succeeded with your help on boosting it. Then i started getting the unit going blank on me. I decided to delete all the data on about 6 months of running off my unit to see if it would help my unit funtion ,

Re: 205 Forerunner Turning off

May or may not relate to the above - My wife's would show full battery, turn on ok, find sats ok, but as soon as she tried to put it around her wrist it would turn off.
Problem was the front (containing the screen and inner electronics) part was coming away from the back part (containing the strap and internal battery part) when she was tightening it around her wrist the electonic board contacts separated from the battery - hence instant switch off.
Solution - using your finger nail separate the two parts, apply a fine layer of superglue to the joint push two parts back together and hold. CARE dont get superglue on any other part, it will melt the plastic and leave a mark.

Did you try updating the firmware of the unit?

Also, did you try to reset the unit?

Press mode and lap/reset simultaneously to reset the unit.

Also, try removing the battery and cleaning the contacts.

Re: 205 Forerunner Turning off

Sounds like the unit is damaged (hardware) you can try resetting it by letting it dischagre and removing the internal battery but i seriously doubth that will help.. I think it might be a short in the device itself could be eighter cracked solder(most likely) or a loosed component.

If you wish to try fixing it your self you can download your service manual
but it will be better if you take it in to a technician..

If you choose to attempt repair your slef or your just curious

1.) open it up
2.) gently tape different parts of the surfcae with a small plastic device such as a pen cover.
3.) try to isolate the componet or part of the board that is shorting by doing that
4.) once you fount it cafefully examin the solder by clowely rocking the componets to identify which is causng the problem.
5.) look at the soldering holding the component to the board.
6.) if its cracked (the cracks can be very very small) re solder i
7.) if the pins attached to the componet it self is coming loose you will need to change it..

Garmin 295 forerunner will not turn on


Did you mean the Forerunner 205?
It is most likely that the battery has died in the unit or there may be a problem with the battery charger.
The internal battery in the Forerunner 205 is not user replaceable and the unit would need to go back to a Garmin repair for replacement.
Please call Garmin Tech Support for assistance.

I reinstalled the driver of my garmin forerunner 205 but it is still not recognized by my computer. it has been working for over a year but now I do not get any connection and the device is not recognized...


When you connect the unit to the cradle is there any reaction from the unit? I would try using a different USB port and cord first if this dosent fix your problem the next step would be to obtain a new cradle for your unit. They can be purchased here

Hope this helps!

Battery is fully charged on my 205 and yet it turns itself off

Can it be turn on when the device is attached to the cradle with electric supply?
If so, I think the battey is aged and it cannot be charged to the operating voltage to turn the device on.
A change of battery is required.
I had such a case recently.

My forerunner will no longer turn on or even charge, can they be repaired or am I best to buy a new unit?

Garmin will repair it for about eighty bucks.

But first, try cleaning the electrical contacts on the forerunner and the cradle by rubbing them with a pencil eraser. The slight abrasive should remove any oxidation on the metal. A bad contact between the unit and the cradle could be your problem.

Garmin Forerunner 205 Battery won't charge. A few

Hey everyone. Just called Garmin and got it fixed. Sometimes the forerunner goes into power saver mode and needs to be reset

1. Hook up the usb cable and docking station to the computer.
2. Next, hook up your forerunner to the Docking station - It should pop up saying battery charging in progress
3. Leave it all hooked up and Hold the Mode and Lap/Reset Button together for 15 seconds - screen should go blank.
4. Let both go - should pop back up saying battery charging in progress.
5. Let Charge 20 minutes and it should be good to go.

Hope this helps!!!

Garmin forerunner 205 won't stay turned on

The battery circuit connects to the main board with spring clips, near the top of the case. If the case is coming open it can cause the unit to spontaneously turn off. These spring clips may also be a little corroded from sweat or water that has leaked into the unit. Try squeezing the top of the unit gently a few times to wiggle the clips inside the case.

If you feel up to it you can open the case, clean and bend the clips, and seal it back up with silicone adhesive.

Computer has a problem communicating with my forerunner 205

I just got off the phone with garmin tech. She helped me solve the problem. Here are the steps.

1. Go to

2. Download "Forerunner 205 Ver. 2.80 as of Nov 12, 2007", unzip it, and browse to the folder you unzip the files to.

3. Make sure your Forerunner is connected to your computer and turn it on. Drag file "048401000280.rgn" and drop it on "Updater.exe". A screen will pop up, select "USB" then click OK. Then wait till the process completes.

4. Go to the website on Step 1 and download "Training Center For Windows Ver. 3.3.4 as of Feb 29, 2008". Install it.

5. Run Training Center. At this point, I am able to send/receive data to my Forerunner.

Hope this helps!
