Ok. So glovebox out, (not forgetting the two hidden screws behind the discchanger and AMI). Interface plugged in for trial use, simulated reverse with positive supply and video comes onto the screen.
So, great so far.... However, when I remove the positive input the MMI screen just goes black. Only when I switch the ignition off does the MMI screen function again?!?! Can anyone help, cos as you may have guessed electronics is not really my forte. TIA John

Nothing is as simple as it first seems.
Any chance, John, that you could attach a copy of the add on connection diagram? With my setup I needed three supplies. 1 Constant 12 volt 2 Ignition fed 12 volt 3 Reverse 12 volt. Of course it also needed an earth. Then there was video in, two connections actual video and the screen. Mine is more complicated than yours because it can do many other things but I only use it for the reverse camera so I have a few unused connections.

Hi Ray. Thanks for the input. I've wired the interface in and replaced the glovebox, that's enough for tonight.
I'll have another go on the weekend. I'm probably missing something simple enough cos I'm tired and it's dark or creating a problem by not actually fitting the thing and following the instructions. I've seen wiring diagram somewhere, so maybe that will help, I will post it up if I do find it.

I'm out all day Saturday in York with a 12 metre coach but might be available to come and give you some encouragement on Sunday.

Just to add a bit more info, the wire from the camera to the interface is sort of phono to phono with red wire pigtales, if that makes sense,... I'm not entirely sure what the purpose of the red wires is.... I don't have a wiring diagram as such, just the 'manual'.
Hopefully the attached images will explain what I'm going on about.

The red wire is to send power down(+12v) if you need it. Either way, as required.
In my reversing camera install I take the +12v locally from the reversing light to power the camera AND feed it down the cable to power the interface box (which is in the cabin at the front of the car). The box is earthed using a convenient earth point - there are loads. BUT mine is a D2 and interfacing to an RNS-D so lots of interface differences. Also I can live without the 3 different power feeds as I have to manually switch the display to TV (= camera) whatever power setup exists. Though interestingly I do get "blank" screens (and no sound) at times, though I do know why. The RNS "remembers" that it has TV input even when the camera has no power so displays blank. Though various events cause it to switch away from that mode so it's never a problem.

Cheers HP. Having thought a bit more, and read a bit more I've realised they're trigger wires. I'm now wondering if the MMI will resort to normal after the car is driven above a certain speed... Like when the parking distance control switches off. I'll have another bash when I've more time/light/patience.
Cheers Chaps

John, sorry for the slow answer, I bedded early 'cos I had a 03:00 this morning. I'll pm you my number so you can call me Sunday.
HP, thanks for your input, you are correct about the red tails. Because I have used a video transmit/receive between the camera and the add on box I did not run a video cable front to rear, as an afterthought I do think that I managed to overcomplicate it, but it works absolutely hands free for me. But I used the more expensive x-carlink.
