I have a Sony CD/DVD/MP3 unit. Great peice. Get one that has inputs for a MP3 player, you'll never use CD's again! Mine has the RCA inputs on the back, many have a small jack on the front for easy access. I second the remote. My radio is in the cabin and have a full function remote on the dash. Thought about adding a smaller basic remote for the transom for when the boat is on the lift. Easier to operate in the slip then.
