DIP switch settings
I used what I would call the old style GVIF unit which I located under the left side seat beside the Land Rover Nav computer/dvd device. That one in the eBay link is what I would call new style but probably does the same thing as the older larger silver coloured metal box.
For the DIP switches, the settings are as follows for the factory NAV computer and factory NAV display with aftermarket camera.
1 ON; 2 ON; 3 ON; 4 ON; 5 OFF; 6 OFF; 7 ON; 8 OFF Again these were for what I call the old style but seemed to be correct for all units out there for Land Rover LR3 / D3.
I did have some difficulty with the HLCDCA0001 cable; that is that three ended cable I spoke of.
The cable end that connects into the factory NAV computer, LR IN, seems to fit OK into the socket in the rear of the NAV computer but I felt had difficulty making a tight electrical connection.
It took me many attempts to get the NAV to display correctly. Initially, while the reverse picture would show, the NAV map picture would not.
Instead I received a message saying No Nav Signal Available. It took me until the day after I did the install to get the plug to send signal; a day later when I sorted some of the wires at the GVIF to make the installation better looking, the Nav signal/map disappeared. After I repeated plugging and unplugging of the LR IN end, and eventually all was well again. As such, I think the signal connection inside the connector is not the best and perhaps should be tighter right at the contacts.
That is about it for "secrets". Also I took power for the GVIF from the same circuit parts of the infotainment system are hooked up to, F58P in the fusebox behind the passenger side glove box. F57P would probably be OK as well. You want a circuit that eventually goes off but follows the NAV display/multi-media module power, and I think that is F58P.
Power to the infotainment system tends to be controlled by the opening and closing of doors and the door locks rather than say the radio on off volume knob or ignition key.
As far as sound is concerned, I am not certain what you are referring to as I only used the GVIF for the backup camera and it did not have any mic/sound associated with it.
