Remove the SD Card from the device and insert it into your computer's card reader.

This software will allow you to update the SD Card you removed from the radio, using your computer's SD Card Reader to update the POI Navigation software in the Magnadyne radio. The attached manual will take you through these steps. I updated all my maps to include activating the 3D option for about $80.00.
