Garmin Device Displaying the Message "Memory Battery Low".

The Memory Battery Low message refers to the circle battery that is attached to the motherboard of the device. This battery is used to save settings, almanac data, and user data like waypoints, routes, and tracks. If this battery dies, the information will be lost and the device will no longer be able to save any future data unless the battery is replaced.

Unfortunately Garmin is no longer able to repair many of the devices that use the memory battery. Search Marine Product Support for specific unit, for contact information.
