Here is a picture of the screen when it first arrived:

Thing you have to note here is the centre console around it is actually brownish and not jet black. But it isn’t noticable and I actually think it looks fine against the jet black.

Number 3

The back of the new unit:
I put some numbers on it:
1-2 form the harness pictured above. The harness also connects to a Can-bus decoder. Which has a lead coming from it that then connects into one of the leads coming from the adapter where the number 3 is placed(I call it the extras cable, as it has lots of extra inputs and outputs. Audio out and aux in, rear camera input etc.). This is were I went wrong with the console buttons and steering wheel controls. I didn’t see the wire coming from lead 3

Also you will see a cable at the bottom left of the unit, that is the aerial adaptor, you plug that in, then you plug in the vauxhall aerial cable in to the end of it. Oh and the black cable hanging to the right of the picture is the USB cable. It just has a standard usb port at the end for you to plug in a memory stic/usb drive or even an ipod cable(can’t confirm if it works or not. But what I can say is it doesn’t work with the iPhone. I just stream my music via A2DP using my iPhone)

Number 4

Front of the new unit:
You will see a small white connector on the front, you plug the touch screen in to that. There is a lead that you plug in to the touch screen then you plug it in to the unit.

That’s about it. Basically you plug 4 cables in to the back of the unit. 2 of the cables form the Harness + Can-bus decoder. The other is the extra’s lead like audio out and aux in, rear camera and speakers etc. Then the aerial lead.

The can-bus adaptor has a wire that plugs in to another wire on the extras lead that makes the steering wheel controls + front console buttons active.

Then you plug in the screen and attach the GPS aerial to the back of the screen it just screws on, it is the gold plated connector shown below:
