The D2 Forums

That makes sense. Will have to consider the rns-e upgrade or try to wire the tuner to worn only with the RSE screens. Maybe I could be possible to mount a rns-e button kitt without display in the rear center console to control the modern tuner.

Personally I know absolutely nothing about the D2 Rear-Seat Entertainment system, though I always assumed it was totally independent of the RNS.

The RSE cars have a special version of the RNS-D that has a video output that can mirror whatever is displayed on the front screen on the 2 rear ones. It also has a remote control input from the rear center console so that the rear passengers can control the entire system including Nav input and so on. So it’s not totally independent but the rear screens can also display from the rear dvd player and also the tv tuner. Now typing this out I realise I’m not 100% certain of this since I have never been in a RSE car but maybe Dean will chime in to correct me if I’m wrong since he has one.

Going away from RSE and considering RNS-D vs RNS-E one of the "features" of the RNS-D is that IIRC it supports both NTSC and PAL colour inputs, I "think" RNS-E is PAL only.

As for mirroring the RNS-D screen to the rear seats, the quality/resolution would be awful so I'd be really surprised if it was ever implemented. RNS-E later versions are IIRC 800*480 which still isn't great on a larger display and I don't think that does screen mirroring either.

NTSC and PAL are things I never heard of but the RSE screens are 800x480 so probably not too far off the rns-d will see if I ever find the orginal system from a RSE car but will probably require traveling to Germany and searching scrap yards.

NTSC "Never Twice the Same Color" is the US standard for colour TV at 30 frames per second, a lot of reversing cameras have that output standard.
PAL is the European standard for colour TV signals at 25 frames per second. It has a very different (better) way of encoding the colour information.
This is the layout of the Video input connector on the RNS-D, it has a pin to signal PAL/NTSC though I've no idea which way round that works.
When I had a TV tuner (PAL) alongside camera (NTSC) it all seemed to switch automatically, but that may be down to the CVBS to RGB converter unit I use.
