Hi All. I recently added a DAB kit to my stereo and removed the head unit so that I could get to an ignition live. The problem is I have put it back together and now the heated seats and parking sensor buttons do not work. I reconnected 3 leads to the airvents. Can anyone assist me? I cannot see any spare cables, except one that I am sure what laying in there when i took the stereo out and it does not fit the stereo anyway! Thank you in advance. BTW - I have checked the fuses and the parking sensors do work, its just the buttons do not work.
