Can a remote be added to this unit? if so, what model works best

The best solution you'll get from books at www.reliable-store.com

These are books containing info on repair, service, troublesho oting, parts info, assembling dissemble, removal, error/fault codes, wiring diagrams and everything on any vehicles cars, atv, trucks. forklifts, boats, excavators etc

probably picked up the wrong power wire for the unit and the power is diverted to the ignition circuit.. have the installation checked by professional audio fitters.

And the unit is?

I know this isn't going to help you but I have a similar issue. The remote will function IF I first turn on the radio from the radio unit itself. Yours should turn on when the boat turns on, as mine did once. Now, my remote will not turn on the radio but will control it once I take the step mentioned above. I suspect I have a faulty remote. Coincidentally my battery now loses it's charge after a couple weeks of no activity. Perhaps a short in the remote unit causes a slow drain.

The best thing to do is use a factory wire adapter. The main wires you need to worry about are power, battery memory, ground and speaker wires. If you have a power antenna you will need to wire in the remote (normally blue or light blue). The only other wire should be an orange wire for the dimmer on the radio face. This one is not necessary for normal operation. Make sure you have the main 11 wires wired in. Ignition, battery, ground and the 8 speaker wires.

best is to buy a kit from walmart or auto parts store, plugs in stero and wiring from car

The stereo with remote is model KD-S600. Unfortunately there was not one for the 550 version.

hit learn button for 10 seconds. now nothing will work except wired buttons. Hit learn for 1 second and put in yur 4 digit keypad code and hit enter, light on motor will blink twice. hit learn again for 1 second and push button on remote. again bulb will blink. continue pushing learn for 1 second and adding another remote.

Maybe it is a boat anchor. Recommend contacting a local car audio professional or Clarion customer support directly here:
