Garmin satellite navigation devices use a global positioning system to provide turn-by-turn directions and navigation instructions. A Garmin GPS is driven by a computer processor and like any computerised device can experience freezes or crashes that stop it from functioning. To repair your Garmin if it stops working, you can use the "Reset" feature built into the device.

Skill level:
Moderately Easy


  1. 1

    Remove the Garmin from its cradle or mount.

  2. 2

    Press the "Reset" button beneath the GPS's antenna and hold for at least 10 seconds. Alternately, you can press the "Power" button for 10 seconds if your GPS does not have a "Reset" button.

  3. 3

    Turn on the GPS and it will be returned to the original factory operating condition.
