Well, here we go.
I have took out my Pioneer DEH-4000 from my Astra and put it in to my Vec.
I bought the 99-X45 loom to go with it.
The Pioneer works fine but the SW Controls dont in the Vec

I have tried using the 099-X06 from the Astra with both Patch leads but still no joy.
The SW Controls work fine with the orginal CCR2006 HU.
Also the Pioneer works fine in the Astra with the SW Controls.

SSSoooo,where do I go next?

Car is a 2002 (52) 1.8 Elite.
It has the 3 buttons on each side of the SW and the GID Dispaly.

According to autoleads the 99-X45 is the correct unit but it aint working..lol..
Cheers
