Memory Battery Low on GPS II, III and 12 series

Certain GPS devices utilize an internal memory battery to ensure user data such as waypoints, routes and tracks can be stored when no batteries are in the device. If this message appears, it is possible to recharge the internal memory battery of the device.

To recharge the internal memory battery in the GPS II™, GPS III®, and GPS 12 series GPS navigator:

1. Insert 4 new alkaline batteries or plug the device into external power
2. Turn the device off
3. Let the device sit for at least 24 hours
   

This process may allow the internal memory battery to recharge. If the low memory battery message continues to appear, the memory battery has failed. Garmin is no longer able to repair or exchange the GPS II, III, or 12 series devices.
