The KCA-RC107MR wired marine remote is an excellent addition to your Kenwood marine stereo, allowing you to control the music from just about anywhere on the boat. Kenwood made this CA-EX7MR 22-3/4-foot extension cable for installations where the remote’s 39″ cord isn’t long enough. One end connects to your remote’s cable, the other plugs into your stereo. Warranty: 1 year.
