I looked at those options before adding a radio to my Roadking. With a bike that doesnt come factory with a radio there is alot to overcome. I felt that for the price however I could do something that would both look and function better. I feel that xm is the only way to go on a bike in that you can go across country and never have to change the channel, also the mounting size of a xm receiver is smaller than a head unit. If you have any questions regarding equipment or mounting feel free to ask.
