Hello & Welcome to Just Answer,
Sorry to hear of any issue you are having with your device or finding the updates.
May I ask:
1) When you did the last update, was that done using the current computer you are using now?
2) What type of computer are you using (window, mac, etc.)?
3) Is the device still working well - with the current maps?
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).
