Hello & Welcome to Just Answer,
Sorry to hear of any issue you are having with your device.
To help you with this issue, may I ask:
1) The FULL Model Name & Number of the device you are working with? If you're not sure and can find the Serial Number back, I may be able to get the model from that.
2) WHEN was this issue first noticed?
I see it has been a few days and I haven't seen a response on this page, so I just wanted to follow up to see if you have any more questions concerning this issue OR if the issue was resolved?
I look forward to any further questions or results that you may have.
Thanks, ***** *****--. .-(im)
The FIRST step in troubleshooting this process is finding the MODEL NUMBER of the device.
MOST Garmin "automotive" devices are called "Nuvi" and are usually followed by a 3-4 digit number, and that model is USUALLY printed on a sticker - on the back or edge of the device.
If you can't find the model, look for the SERIAL NUMBER - usually printed right next to a "bar code" or "QR code". I can usually find the model number using the serial number.
Thanks, ***** *****
