Dear UkenGB,

you need NTSC camera, not PAL.
camera input on TV-module is alwayes NTSC in every country version.
For example : if you travel by car in other country where TV is NTSC, you have to switch tv in NTSC. So your camera should not work..., but BMW are clever and fixed camera input on NTSC. I also bought PAL version, that replaced by NTSC.
you can find realy and wiring diagram searching forum. Also I posted second relay installation diagram, which eliminates engibe noises.

That makes sense and to be perfectly honest, I never had a clue why,thanks.

I'd just discovered this 'fixed' nature of the camera input and yes indeed it makes sense (except they should have fixed it to PAL). Don't you feel better gwc now that you know

ika do you also know about the (composite) AV input to the Tuner module? Is that fixed or variable with the TV setting? Seems to me it would have to be fixed as if you have something like a DVD connected, that will stay the same wherever you travel, just like the camera. But to fix it to either format wouldn't make sense as any equipment you buy to connect to it would be in the default format for that country, e.g. PAL here in the UK and therefore not necessarily the same as that to which the input is fixed. What logic did BMW use on that little conundrum?

I just saw your diagram of the 2 relay setup. Not sure I completely understand why it is necessary though. Maybe that's becasue I don't know the schematic for the relays. Do you have that, what terminals are for the coil and which ones are switched?

AV is switchable : PAL/NTSC as TV.
when you power camera from reverse light cable, it may cause engine noises, like mine did. So I installed second relay and problem gone.
Second relay powers camera directly from battery.

when you put in reverse, reverse light powers pin86 of relay-2 (pin85 already grounded), which connects pin87 to pin30 and camera gets PLUS directly from battery.
First relay just grounds TV-module pin17, to switch in camera mode.

My life is now complete mate

There are two video inputs,one for the rear cam and also an av input for dvd players et al.The second one is selectable on the tv /av channel.

I have my camera on an av switcher along with a dvd stack and a ps2 so I can see behind whilst on the move if needed,its also shown automatically when reverse is selected.

In theory,theres nothing stopping you actually connecting a dvd palyer to the rear cam input but it would have to be a NTSC model and could be displayed at anytime by rigging a simple switch in the front which grounds pin 17 on the module.

The possibilities for wiring it up are only limited by your imagination.

Some great info here http://www.the12volt.com/relays/relays.asp

If i wanr RW cam i will connect yelow RCA to pin 13 and 14, and ground cam from pin 17?
If i want DVD player or otherexternal video source with mono sound i will connect Audio RCA to pin 4 and 5, Video RCA to pin 6 and 15. I know that i can buy a cable, but i acctually like doing things my self

Yes, this is correct.

So when i put car in reverse the cam will go on feeding video input, witch will switch screen to show camera input ?,
BTW do i get + line to camera directly from battery since ground is a switch, or should i still get it from revers lights ?

I'm thinking I want to enable the reversing camera input while driving normally (i.e. forward). Is this possible? I know how easy it would be to rig up a suitable switch, but is that input disabled at speed?

Normal TV or other video display is blanked when driving, for safety reasons, but is this the case when the reversing camera is enabled?

I don't want to have to add a TVinMotion bypass to enable the AV input while moving, but could I avoid this by using the rev. camera input?
