Cd30mp3 to aftermarket head and lost climate control, help

[Firestarter]

I've copied this over from a post I just put in zamora as it probably has more chance of being answered here apologies for duplication

Ive just fitted a kenwood headunit to my 2012 zafira b. It used an autoleads cp2vx52 loom adapter and the aerial adapter. All works fine but. Although my climate control works I have no display on the gid. It flashes up for a split second when I adjust it occasionally but but the small box in the bottom of the display showing temp and fans account or economic is always empty and it means I can't actually turn air con off. Also I can bring up the bc menu with a steering wheel button but not scroll through it anyone any ideas I'm lost. Vauhall say the previous stereo a cd30mp3 had nothing to do with the climate so they don't have a clue either. Auto leads also have no idea
But when I reattach the cd30mp3 I have the display back and full control any help greatly appreciated
thanks

sounds like the auto leads connector is affecting the canbus between the display and ecc unit somehow

Yeah I'm at a complete loss. Autoleads say they don't know. And it should work and vauxhall say the cd30mp3 doesn't interact at all with the exception. Totally stumped

Vauxhall are correct... disconnecting the radio will not affect the ECC.

How about disconnect radio and the autoleads thingy you have then try the ECC?

If I plug in the old cd30mp3 it works fine

Someone on an old thread I found on the Internet said the gid needs telling that no headunit is attached using opcom or tech2 or something but that was never confirmed to work and it's a really old thread

As a test I went and bought a set of new leads from local car audio specialists, a set of connects2 and it now all works. He said autoleads sometimes struggle with can bus and are not worth buying. Luckily I kept the box they came In and got my money back. Thanks for the help
