What to do if my Garmin GPS will not turn on?
If your Garmin GPS won't turn on, first ensure the power source is working. Then, check the fuse in the power cable. Verify the device is receiving at least 10 V, with 12 V recommended. If the device receives enough power but still doesn't turn on, contact Garmin product support.
How to fix Garmin GPSMAP A12 not acquiring signal?
If your Garmin GPS is not acquiring signals, ensure the device uses the latest software by updating it. Also, make sure the device has a clear view of the sky, positioning it close to a window if mounted inside a cabin, so the antenna can receive the GPS signal.
Why is my Garmin GPSMAP A12 creating waypoints in the wrong location?
If your Garmin GPS creates waypoints in the incorrect location, the map datum and position format of the device may not match the map datum and position format originally used to mark the waypoint. Find out which map datum and position format was used when the original waypoint was created. Then, select Settings > Preferences > Units. Select the correct map datum and position format settings. Create the waypoint again.
