On my 3700 it was at the base of the electrical panel, inside the plexi cover. It switches between the antenna (buried behind the electrical panel) and the cockpit connection. Your antenna, if you have one installed, needs to be powered to work, there is a power supply behind the electrical panel or below it, behind the aft dinette seat back (where the battery charger is located) at least that's how my boat is arranged.
