My 04 1150 rt does not have a radio. Can i install a satellite radio on the bike without an existing radio system? I would really appreciate any feedback on this topic. I'm a little confused with what I am reading online. I would like to hardwire a dock on the bike, in a location that would be best for the unit to avoid excessive vibration. My helmet is a Nolan 104 with the N com system (speaker source). Thank You
