Hello & Welcome to Just Answer,
Sorry to hear of any trouble you are having with your device.
May I ask:
1) The AGE of the device?
2) If the device still works well - with the current maps you have?
3) Do you have a USB cable - for connecting the device to a computer?
I see it has been a few days and 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, ***** *****
