Right, got my car back from the bodyshop
Set about stopping the rattle in the top vent which I'll test tomorrow though while it was all out I removed the headunit to try and connect an MDI cable and swap pins 2 and 3 as someone suggested this will stop the buzzing I get as I accelerate.
Was present with this mess
Now from I can tell... the proper connector is not being used and it's been bypassed....
Anyone shed any light or tell me if the soundpack is actually being bypassed
Wanted to sort this tomorrow so any help would be much appreciated.
Also anyone know what this is and if it's a reason for the special setup???
