PROBLEM:

So there I was driving along listening to my CD when the CD Player and Centre Display which shows the time, radio, Blowers etc when off....

The only life I can get from the Control Panel which is the middle of the two is the rear heater ... all other controls are dead... and the CD player wont eject the disk...

The heater is stuck on hot blowing and the only way to turn it off is to take the fuses out

I got an expert car electrical guy out and he say the units all have power going to them.

So I assumed it was all to do with the main display or to give it the correct part name: DISPLAY ASSY-AV so off to EBay I went and bought another one....installed it today and still nothing... Having replaced all three units now its still dead :(

FIX:

Took it to the dealership and they found that the units only had 5 volts going to them.

They stripped back the wiring loom and found two broken wires in the engine bay loom. They soldered in new lengths of wires, insulted them and tested them and now its all working!

Hope this helps someone :)
