All be careful with the new car updates. Mine was updated to the latest code this past week and the nav update fails. The error was similar to the following:
The navigation data in the car is incomplete or has been manipulated. Please see your service center for more information.
So either wait to update your car until the nav is done or we'll have to find the cause of the issue.
Any ideas here? I tried the USB method which doesn't work at all and the DVD which resulted in the error. I'll capture the error better next time after the ECU resets because it won't show again at the moment.
