Hi there,
wonder if anyone is able to help me - last year when I bought my '08 Astra Club I bought a CD30MP3 on ebay, this came along with the BID display (Old unit was TID). I lost access to all the battery voltages, trip counter, MPG etc that I had access to on this display beforehand - I'm a bit clueless on this sort of thing and have no idea how to go about possibly getting these functions back.
