I've got a 2002 pre-facelift GSi - which i wanted to to change and upgrade the CD headunit and screen, to a satnav version and colour screen.
I obtained a NCDC 2013 and screen which i was told are paired and are fully working.
I thought that this would be a straight swap out? am I correct or not?
The old HU came out and the new one slotted in perfectly and the same with the screen, however, the HU turns on and all i hear is static from the radio and i cant switch to CD, in fact no matter which buttons i press nothing seems to happen. The screen turns on fine with vauxhall logo and outside temprature displayed and thats it. the control on the wiper arm doesnt do anything either.
Have i missed something? are these symptoms of non paried units? or is the HU faulty?
Any guidance at all is appreciated or even better if someone could take a look at it for me that would be great - im prepared to travel.
Thanks guys, this is doing my nut in.
