I'm in the same boat and have tried everything just like you. Called and tried to find a Satellite number associated with my brand new Disccovery for at least 30 minutes, nothing worked. It wasn't until my service checkup that someone from Dealership finally confirmed for me it is not capable of being installed in my car and I'll have to go through my iPhone app to use it.
It's the only thing I'm upset about with the car. But, have to move on.
