In NA the only available interface for the telephone to work through the handfree prep that is included with On Star is for a Motorola phone.

In Germany there are several other options including Nokia and more importantly a Bluetooth cradle. Is anybody familiar with this and if it will work with the NA cars.

Thanks,
