Electronics Repair Questions? Ask an Electronics Technician
Hello & Welcome,
Sorry to hear of any issue you are having with your device.
To help you with this issue, may I ask:
1) Can you CONFIRM the FULL Make & Model Number of the device you are working with? I only ask because I don't see a Nuvi of that model number.
2) The AGE of the device?
3) Where are you seeing map file names you listed above?
