You don't say whether you're using Bluetooth to connect your phone to your vehicle? If so, is any audio coming out of the vehicle speakers (music, etc)? Have you looked at the profile for your Bluetooth connection?
You haven't given us much to go on.

I figured it out. I'm using bluetooth. Had to turn on "mode" on the steering wheel then switch to any music stored on my phone. I could then listen to the music and hear the GPS directions through my radio speakers. The GPS will not play through the speakers when using satellite radio.
