nvx200

When I try to go into points of interest, a "fatal error" message pops up and says "file format error". Also, some addresses I try to search causes the screen to freeze and I have to reset the device. Any suggestions?

hello i have had the jensen nvx200 gps for about 1 year when i had to use my digital camera for important pictures but i needed a memory card for the camera so i took the one out of the gps and my camera formatted the memory stick for the gps and i put it back in the gps and no maps or anything...
