Just bought a new 2010 coupe and the satelite antenna box won't stay stuck to the top of the windshield.   It came with a 1 1/2 inch wide piece of clear double sided tape to attach it and it keeps falling off.   I haven't taken it back to the dealer, but thought that someone may have found a better way to keep it in place permanently.

I have the same problem.  Apparently there is a service bulletin in regards to that problem.  My dealer informed me there is a bracket that has been ordered and they will call when it gets in.
