Hi new to the forum hoping for some help i've put a cd40 dab system into my 2007 sri cdti ive unpaired the old info screen and paired with colour screen from navi, problem I have is that pin 17 and 18 on the info screen are the mid can wires from the climate control, these pins are DAB box can wires on the old triple info screen, can you have climate and DAB? is there any other CAN wire inputs on the screen, the wiring diagrame on this site shows some vacant pins, but not what thet are.
many thanks for any help
