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 was used to update the device?
2) When the update was finished, did you exit the program AND then "safely remove" (eject) the device from the computer BEFORE it was physically removed from the USB connection?
3) How much time went by between the update of the device and installation in the vehicle?
Thanks for letting me know that worked for you.
Perhaps the "safe remove" was not done on the first attempt?
Please let me know if you have any more questions.
