I'm wondering about the possibility of running the XM output into the CD changer output (I don't have the changer installed on my 95 E320) and have it switched on through the head unit CD switch.

Is that do-able?

Anybody?

Also concerning interference, I'm wondering about the satellite signal. Is it a geostationary satellite or are there a constellation of broadcast satellites that the receiver chooses from as they come over the horizon?
