Hello & Welcome to Just Answer,
Sorry to hear of any issue you may have with this cable.
May I ask:
1) WHERE this cable was purchased from?
2) Do you have any electronics or computer stores in your local area?
3) Does the current USB cable have a connector (on the GPS side) that is OBVIOUSLY the wrong size or shape?
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)
