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 AGE of the device?
2) What is the CURRENT STATUS of the device? That is, does it still work well - with the current software and maps that you have installed?
3) Do you have a USB cable and computer - for connecting the device to the computer?
Please use the REPLY box below, then click the SEND button.
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)
