I have the J&M system I just pulled from my Connie. Used only this summer. Just like new. It is complete for Concours. Has the handlebar bracket, and antena bracket and antena. This is a solo set up. It if want to ad passanger you must get the other plug from J&M. It is set up for use of CB, intercom (with other plug) it has a mini hook up plug to use for MP3 player or fm radio or walkman. It also has the NOAH weather radio. It is a 6 pin J&M and you will need to get headset and cable for your helmet. (NO headset comes with this).
