I have just installed a JVC KD-BT1 bluetooth radio in my 1983 300D, and can heartily endorse it. The bluetooth radio is awesome - It is fantastic to be able to drive and talk on the phone just like the person on the other end was sitting next to you. The bluetooth and USB connectivity is also great - I know that you can get a satellite radio to hook up to this unit as well, as I saw it discussed in the manual that came with the radio. I personally am not into satellite radio, but with USB connectivity and IPOD, that gives me a HUGE choice for music. If you talk on the phone while driving, you might want to look into this, as it is worth the price of the radio for that feature alone!
