It depends if you have a half-canbus car or a full can-bus car.
On the steering wheel, do you have 2 scrollers or 6 buttons???

If you have CD30, or scrollers, then you have full CANbus set up.

If you have a DAB box, then you can make up your own little loom, but you would need the 18 pin connector (as found on the TID displays of half CAN Vectra's).

If you do not have the additional DAB box, then it is more or less plug and play
Just need to check the 32 pin display connector for the power wires..

Some TID's have only 1 brown (earth wire on pin 1) and 1 red (battery live on pin 5)

The GID (Graphic screen) will need 2 browns (pins 1 and 2) and 2 reds (pins 5 and 3).

Other than this, you are good to go.

Do remember about the DAB aerial if you are fitting a DAB box.. try a patch aerial for simplicity. Saves routing fresh aerial wires along the roof, and changing the aerial base to include the DAB aerial component.
