    Nav screen says "hang up" when car is turned on

    When I start the car the nav screen thinks I am in the middle of a call even when I am not. It has the "hang up" sign in on the lower left screen and nothing else works. I have to make a call and hang it up to get it to work again. The rest of the touch screen controls are all frozen when this happens. It happens both with my iPhone and my wife's blackberry. It used to be intermittent but now happens all the time.

    Is this a known problem with a TSB fix? It was sporadic and I would take it to the dealer and of course it wouldn't do it then. They offered to replace the whole radio which I would do but we actually had some similar issues with our prior 08 CTS4.

    Anyone else having these issues?

    Thanks

    I have this problem periodically. I have to turn the car off, open the door, close it, then start the car again..
