I decided it was time to put satellite radio in my 2K CLK 430 and got a disapointing surprise. As far as I can tell, you can wire an aftermarket satellite radio into every car but a Mercedes. (That's unless you want to buy a new, 2005 model with sat. radio factory installed) The only option appears to be those lousy sounding radios that transmit to an unused FM channel. Somebody tell me I'm wrong. Does anyone make an aftermarket sat. radio for me?
