mfd2 av wiring help

[cuprajake]

Hey guys in need of help. 


I have a 2007 seat Leon cupra with sat nav. 

I mistakenly thought I had a rns510 and bought the av interface. Only to find out I actually have a mfd2 lol I cannot return the interface so I'm stuck. 

Here's what I'm doing

The vid shows the motorised seat badge handle I've made. The plan is to place a small camera in there and run through the av adapter. 

Heres my actual unit. 





And here's my connector that's actually for a 510





I've found a pin out of both together


Here 





the only difference Is the rgd have their own earths.  Are the common or not. How can I wire it or is it best to sell n get a new interface


Cheers jake
