Hello & Welcome to Just Answer,
Sorry to hear of any issue you may be having.
May I ask:
1) HOW LONG have you had this device?
2) Was the device purchased as NEW or refurbished?
3) Have you tried to charge and use it yet - using the Vehicle Power adapter?
4) What tool (program, etc.) are you trying to use to register the device?
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)
