Just fitted my old alpine cdr113bt to my vectra c 03 and used my astra g cables i.e. patch lead, stalk adapters etc. Plugged the adapters in correctly i think well were they fit and connected the phono lead coming from the auto leads block to rem on the head unit but the only button which is working as it should on the steering wheel is the source select button every other button turns the HU off?

Hope someone can help as this is doing my nut in

Also were should i put the wires when this problem is resolved? cause they are too bulky to push the HU back?

Was hoping to get this done today but these problems have put a spanner in the works!
