<snip> Had open ticket with GM, they forgot me ad my problem.....
This site offer no help other than providing a number that I had already exhausted. GM is paying for disc, as they should since, but only after a long discussion with them... I have full warranty and ordered car with a NAV. Don;t know if this disc will fix, we will see. it is suppose to be here Saturday.
I drove 8 others that had the same issue, so the problem is out there. keep my fingers crossed.......very disappointed with GM though....they dropped the ball even with follow up to an open warranty claim issue.....But, still love the car..
