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) What program are you using to try to update the maps?
2) When you say the program "jumps back", what are you seeing (on the computer) when that happens?
3) The AGE of the device?
4) WHEN this issue first began?
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, ***** *****--. .-(im)
