I really like the looks of the MP56 and I would have loved to go that route. One complication, my iPhone.

It seems the only BT connection I could find that would definitely pair with the iPhone was the Pioneer DEH-7000BT. Thankfully, with reviews of ppro's DEH-980 everything went smoothly. I wouldn't let the fact that you might have to connect some wires to another harness deter you. I'm totally electronically dislexic and I had no problems. All the wiring to the new harness is done outside the car. Once done it's plug one end in to the new radio and the other in to the car's harness plug.

The DEH-7000BT does NOT look as nice as the MP56, but I can pair the iPhone now. I added XM radio for $99 and the additional aux port so now I have BT for the phone, USB connection and 2 Aux In ports. May not look as nice as yours, but it sure is functional.
