All sorted now Sean
But I'll send you my email anyway as there seems to be many combinations of wiring for the various ICE options if you can send what info you have.
In the end I had to cut the orange plug off and join:
Green wire (Steering-key1) and connect as shown below to brown wire pin 1 of ISO3 labelled (Manual brake close screen testing line)
Join:
Black (steering ground) to PIN 3 Blue/White DD ISO 3 (which in your instructions says not used) But is crucial to connect this as
PIN 3 of ISO 3 on the Rover loom is Paddles ground BLUE/Purple.
BLUE ORANGE is paddles +ve
After that the configurations screen was already set so the steering controls now work as they should.
