I move my Sirus receiver between two different docking stations ("docks"). One dock is in the truck and the other is in the trailer.
- The trailer dock is wired to the trailer radio's Aux input. I have a panel antenna mounted to the top of my TV antenna mast that I rotate as needed for max signal (worked awesome up in the arctic).
- The truck dock is connected to the trucks radio via a "FM Antenna Adapter" (the truck radio doesn't have an Aux. input). Also works great, just have to set the FM radio to whatever frequency you have the modulator in the Sirus radio set to. Don't waste your time fiddling around with FM direct (wireless between the Sirius radio and your truck radio). I have a "trucker antenna" mounted to the canoe/kayak rack on top of the canopy which works well (also worked in the Arctic).
- IF you really want Bluetooth, there is a Bluetooth adapter available that you plug into the audio out port on the dock that transmits a Bluetooth signal.
All this stuff is available
here.They are very helpful and have prompt service.
BTW. Even though Sirius/XM is one company now, the two services use different satellite constellations. So if your travels might take you to Northern Canada and Alaska, stick with Sirius.
Hope this helps.
