My old Garmin 305 GPS wristwatch has recently started to misbehave.
- The sound, when turning on the device has almost disappeared.
- Display sometimes shows nothing or just some pixels.
After charging it once again, I wondered if it could be reset somehow.
By holding simultaneously Mode + Lap/Rest + Power, then it should be reset. Sorry not. Didn’t help.
Then next thing was to install Garmin WebUpdater. This delete the Garmin sw and re-install a new version. If this process fails, your device is lost, I could imagine, so it is very important that your PC runs on power-cord, so it does not loose power and also internet needs to be reliable and not the least – the Garmin has to be fully charged.
Since I had nothing to loose, it was just to try it out. Executing WebUpdater did not show a device, even though I had the Garmin plugged in and even though I pressed the “Find Device” button in WebUpdater. Re-plugging Garmin made it possible to connect.
The wizard only needed a few “Next” pressings before the new version became installed. It took maybe a couple of minutes. After that the device was working fine again except for the sound. It was still almost unhearable even with the ear very close to the device.
