Common connector on marine radios you have not listed is one for a
remote control panel. Could it be for that? It's probably described
in the remote control installation manual, not the radio manual.

Bought a Kenwood KDC-35MR marine radio from Ebay. There is an extra
port on the back that I can't figure out what it is. I've downloaded
the manual and the picture does not show this port. On the back of the
radio, right side, there are two RCA imputs and the 16 pin connector.
On the left side there is the CD changer port the antenna port and a
third water tight connector. THis water tight connector is nowhere to
be found in any of the manuals I've found anyone have an idea what this
is for. I can email a pic if anyone can help..Thanks
