GPS devices help users get directions when they are on the road. Turn-by-turn,, voice-guided navigation makes them popular accessories for drivers. But roads change, new developments pop up and new routes are built. GPS maps need to be periodically updated to continue giving accurate directions. For Nextar GPS units, upgrades are available through the purchase of an SD card directly from the company.
Determine the serial number of your Nextar GPS by looking on the back of the unit or on the box it came in. There are two different SD card map upgrades available, and you will need to know the model number and serial number (for certain models) to find the compatible card.
