You should be able to sync your phone with the Trac's Sync system via Bluetooth. When I had a MS-Sync-equipped Fusion as a rental on vacation, my phone synced right up with it via Bluetooth. Check your owner's manual for instructions.
I hook my phone up via USB. I have an Iphone and when using bluetooth the skip song buttons on the steering wheel do not work the phone. When I use the usb, in my opinon, the music sounds better and the steering wheel controls work my phone.
