Thanks for that, but still not clear on some issues.

Why would I need an NTSC camera?

The TV Tuner in my car has to be PAL, surely the camera would need to be PAL.

Thanks for the link to the camera, I will probably do the same as you.

Did you have to drill a hole in the tailgate behind the emblem?

Does it show a mirror image?

What is the field of vision when it is mounted in this way?

I need to be able to see the towball, will it show that or is it too high. I like the idea of this camera mount as it is smack bang in the centre, unlike the OEM BMW kit which mounts the camera off centre. I just need to know it will show what I need.
