Garmin gps powers off even when fully charged

If you're "recharging" via the car charger - you might want to try charging via USB jack on your computer - or AC adapter (if your GPS shipped with one) for 5 or more hours.

Many Garmin units develop this condition when used strictly in the car / cigar outlet power source. While connected to your computer, you should go to Garmin's website and download, install & run the "webupdater" software. When complete, your Garmin GPS will have the latest firmware and patches to the software (not maps!).

After charging via USB or AC adapter, your GPS should stay on. If your GPS turns on via a slide switch on the top, Slide the switch from OFF and hold in the ON position for 10 seconds before letting go of the switch. This should force a "boot" on the GPS.

If you're unable to get the device to power up, contact Garmin Support to determine if your device is affected by a a recent battery recall or if there are other suggestions they have to solve the problem.

I hope this helps!
