Hello & Welcome to Just Answer,
Sorry to hear of the issue you are having with your GPS.
May I ask:1) What tool (program) are you using to "download" information to your device?2) The AGE of the device?3) WHEN this issue first began?
4) Is this the FIRST TIME you have connected the device to your computer?
5) What is the approximate internet connection speed that you have - if you know that?
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, ***** *****
