I picked up a Belkin AirPlay Bluetooth receiver last fall. Since I have a 1SS, I don't have a PDMI module. Instead of going out and buying one and then having the dealer reflash the stereo this works just as well IMHO. It connects to any A2DP capable device and plays anything you want. The only thing that really bugs me about it, is when you start the car it doesn't auto sync to your bluetooth device. You have to re-pair your device and then hit play on your music player. (Might just be my phone though.) It pairs quickly though and only takes an extra couple seconds to play music. It also has a build in speaker and picks up calls like a champ. I picked it up onsale for $40. A few guys in the club now use this too. Really decent upgrade if your not interested in the real upgrade.
