I have an '05 Vectra Breeze with the CDC40 Opera DAB radio setup and I remember somebody saying that as I have all the hardware in the car (screen etc) it would just be a case of turning on the computer functions in Tech2.

I've spoken to the technician at the dealer, who admits to not being too experienced with Tech2, and he's willing to have a go but asked me if I could find out any further info on where abouts in the settings are.

Can anybody help? Is there a guide/flow chart available that shows the settings?

Its not life or death or anything, but if it could be done...
