It's not strictly ZT/75, but its on a theme.
The OEM sat nav is a bmw based system, and was also carried on into the R50/R52R53 Mini (which I have)
I want to add in a video and audio input via the back of the sat nav drive, which is where BMW added the feed in from the video module when TV was fitted.
I've made the lead, but its the same as this one, except its only one video input
