Got round to putting mine into the calibra on Monday, dead easy job considering Vauxhall were charging £349 for one of these to be added to a car like mine when new!
Anyway, its all working fine, except the Tempreture function, which simply displays an 'F' on the left and no Tempreture. I'm guessing this means my car doesnt have the sensor fitted? which is wierd as its wired correctly for the computer. Iis there another reason, such as the sensor just not working?
before the computer my claibra just had the Quartz Clock.
