Hubby and I have the extreme cycle radio. It is a radio, speakers, mp3 player and plays off of a SD card. They are great we got two in sturgis (one for hubby's road king and one for my then sporty). I moved mine to my deluxe. For what you get it is cheap $275. It is 120 decibels so it is loud. The speakers are also small compared to the others 3 inches.

Check out UNiQ Cycle Sounds. I have them on my bike and work great. Service is good too... Works off anything with a headphone jack (satellite/phones). Systems offer Bluetooth® and FM and all that jazz. They have some new system now too.. Thinking of upgrading..
