Having an issue with the stereo not powering on at all.
Tried 2 different stereos, neither work in the GTI but both do in the polo 6n2. Safe to say the stereos are good.
Here is a pic of the stereo wires. (unsure what the purple and black wires are, but have no voltage at any stage)
I have recorded the voltage of the black plug as I think the brown plug is just for the speakers?
I have checked fuses 20 and 46 and and seem good.
These voltages are as if you are looking at the black plug straight on.
Any thoughts?
