thanks for the replies, im very upset the original owner had all the toys except sat nav! i have taken the whole of the rear left side apart so all that was there was metal and wires big bob, and that damn black plug isnt there, i have looked at the colouring of the wires and cannot find the same wires anywhere else.
as i now have fixed the no voice issue, i just have the reverse signal and speed pulse to get.
big bob do you know what colour wire or pin position,sends out the speed pulse to the pdc ecu? i have read somewhere that its a black and white wire, but guess what my pdc ecu doesnt seem to have a black wire going to it.
i cant get to see the WDS as my pc wont let me(dont know enough about windows settings)
and as for the revers signal, my car is a late 1999 e39 tourer,so reverse lights are in the tailgate, need to get more wire!
