Aftermarket Sirius Radio with PCM 3.0
 

I just picked up an '09 GTS. Bought it through a Benz dealer. The previous owner traded it in for an E63. Anyway, the vehicle has an aftermarket Sirius radio unit installed in the cubby on the roof console for where one would put sunglasses.

Does anyone know how this might be hooked up to the PCM 3.0. What function would I use to play the radio? I don't want to activate the service without knowing how to use it.

Thanks

Copy & Paste as I can't give as a link since they are not (I don't think) a sponsor.

Well, even though I typed this instead of copy and pasting the link, it still came out as a link.

Probably uses an FM modulator.

If you mean Nav-TV, they integrate very well into factory systems. Not an FM modulator. I called them a few years ago when I bought my 09 Cayenne which does not have sat. radio. At the time they did not have anything for 09s but, again, that was a few years ago.

So does this mean I would access the FM tuner then tune to a specific frequency? Or what?
