Got the new unit the other day, but had to send it back to get a firmware update as it wouldn't program. Only a three day turn around, so can't complain.
Fitting it was an absolute pain. I could not remove the harness connector no matter how I tried! So I had no choice but to remove the lower cowling around the steering wheel, and with that bloody lip on it, it was damned near impossible, but after two hours and a trip to Bunnings to get some plastic putty knives, I managed to get it off without having to take the wheel off. Once I got it off, I still couldn't get the connector to release. I managed to shine a torch up onto it and noticed that the release lug had been cut off, which was why I couldn't get it to release. Once I could see what I was doing, I manged to get a flat screwdriver bit that spanned across what was left of the connector and then it released. Don't know why it was like this? Only thing I can think of is that they do it deliberately to stop anyone from easily hot wiring the car. Anyone got any thoughts?
