[grill-n-go]

Our XM is connected to the "car type" AM/FM/CD radio in the TM via some wires that come standard with the XM. I did not have a need for an amplifier. Just tune the radio to the appropriate XM frequency and it plays nicely through the TM speakers.

I use the same XM tuner in the truck. The whole XM cradle is portable. In the TM I mount it on the side of the fridge and run the antenna wire out the nearest velcro flat. I've always parked it on the roof without any need for magnets, since it's only in used when the TM is stationary. When I'm ready to go i take the antenna off and use it on the truck.
