I got a 360 bow mount the other day. Installed on boat and can't get it to work. 360 has two wires coming out of it. Ran one wire straight to battery red and black , to eliminate any other power source variable and other Ethernet cord to the 999. Battery is hot (checked). Also checked all connections.

Under accerssary test on unit it is reading 360 unconnected but is reading everything else temp and gps. Am I not hooking something up right or missing something.
Any info would be appriciated.
