Working on a Sirius install in my 04 C230K sedan. Didn't like the FM modulation sound quality (big surprise), so I bought a wired FM modulator.

Still sucks.

I hear there are two antennas on the Benzo. Is that true? which would someome recommend I use for my wired signal.

One last question. I heard from a bimmer driver that they make an interface for those that splits the signal to the CD Changer. Anyone seen one for our cars?

Thanks.

neither one. None is suitable for a sat radio signal. You have to purchase another antenna for sat signal. Try the micro antennas which can be concealed under the rear deck mat.
