I am adding a carputer to my RV. It has a Visteon CD-6 Sat ready (I have the Sirius Sat kit already installed).

Supposedly it uses the CAN-BUS.

I would like to control it with my carputer - change radio stations, volume, pic satalite channells, etc.

Is there a way to do this?

As a consolation, I have found the converter to allow me to simply pipe in MP3s through the aux input of the Visteon. But it would really be cool to actually control the radio.
