Today I tried installing my parrot handsfree to my cdti. Normally a very easy affair however this has turned in to a disaster. After if failing to work I realised there was also a old factory fitted Nokia unit hard wired and hidden away, so I effectively had 2 handsfree kits wired in series. After reconnecting things the radio no longer works, the climate control, clock and electric windows. I have checked all obvious fuses and all seem fine. There is power going to the radio harness, along with an earth but she still fails to come alive. I disconnected the battery for 10mins and the windows worked for a short period of time before dying. I have exhausted all my knowledge and now need you guys to help. Any suggestions would be welcome!
