NCDR1100/1500 Wiring Help.

[MikeWarner]

Hi Guys. I'm trying to work out what each pin is on my Siemens NCDR1100 Satnav Unit (as fitted to the Coupe Turbo as an option). I have labeled the diagram up with numbers and filled out the ones I know. Also, there are a few I have guessed. Thanks for any help.

have added a couple mike

CAN Bus is to do with the sat nav and is usually speed sensor connections

some connections will be for the steering wheel controls

[Dom]

NC normally means "No Connection" or "Not connected" if that helps solve a couple.

I'd have thought the Shld would be a shield for one of the sensors (possibly the Sat Nav antenna if its got one)

[Dom]

And at a guess - pin 17 could be your reversing lights switch ?

11= diag
6= sync - thatll go to the screen too i guess
9= shield = for the sync wire?
39?30=steering wheel controls
29 = speed sensor
34= illumination

Only the following left:

5. (Ter)
8. (DBC)
31. (AR)

DBC is part of the magnetic movement sensor
