hi guys, welcome to my 1st post, i have looked everywhere without luck to find the answer to this problem, i just prey somebody on here can help me.

yesterday, i upgraded my stereo to the pioneer avh-p4200dvd with a facia plate. all works 100%. better, easier, louder etc. the problem i have hit, is that where the original stereo uses the screen up the top of the dash, it no longer works, thats not a problem for the clock or radio screen, but its a big problem for the climate control as i don't know what setting i have it on, power, air-con on/off, temp etc. any help as to what needs to be done to get this screen alive again would be greatly appreciated. thanks in advance. daz
