Bav Cruiser 33

[ANTREVELL]

Problems with my Garmin AIS 600 and my Garmin 300i.  There is a large black coax lead under the roof lining by the mast which the aerial is connected to. Does anybody know where that lead goes to . I assume it is installed by Bavaria at the factory and terminates somewhere to allow connection to AIS lead. It is not obvious where though.
