About 2 years ago I installed a Pyle marine cd player and 4 speaker setup in my boat. It was a complete kit I found on ebay, complete with waterproof box, speakers, wiring, etc. I've used it about 4 times since then. I'm putting a new interior in the baot now, and the other day when I was in there working on the seats, I decided to listen to some tuneage. I installed the removable face plate, and it powered right up. All the buttons light up and appear its working, but the only buttons that work now are the power, scan, and Mono/stereo buttons. Nothing else will work, no volume, tuning, etc?
