Hello

i was hoping somebody could help me: I have an Astra H 1.7 cdti 2006

I want to upgrade form my CD30 with a GID (Blue) display which Pecky kindly fitted for me years ago. I have just bought a CD70 and CID (24461297 QN) for a Vectra C 1.9 2004 from ebay. They are married and work but when I come to use OP-COM to change the fuel etc the software doesn't communicate with the units. Can any body help or have I wasted my money by not doing the proper research?

Regards
