Retrofitting Factory Sat Nav Help!

[ColinP]

Hi all, i am in the process of retrofitting a factory sat nav using a X3 wire loom.
Reading feeds i have read instruct you to connect the black/White wire to the speedometer, cable pin 6, but i have removed the clocks and i don't know what wire cable pin 6 is or what colour wire i am supposed to be looking for. The PDF file i have downloaded for retrofitting on a X3 instruct you to fit it to the Yellow/Green wire! but there are 2 Yellow/Green wires going to the speedometer. Can anybody please help?

TBH I would have thought the loom would need to be modified to match the Z4 one which only connects behind the Passenger Seat (UK) and then to the monitor and two wire for the head unit.

I don't think you would need to connect behind the instrument panel. A couple of peps on here have done it though so hopefully they will be along to shed some light.
