Here's what you need... It works like a charm, and it takes about 5 minutes to install: XM direct with a BlitzSafe BMW harness. I have installed this unit a couple of times, and it works just like the factory Sirius system. Everything is controlled by the factory radio and all data is displayed on the radio screen -- even the presets work. You can still have a CD changer if you want. I can get them for $200 if you are interested. ([email protected])
