Ok, opted for a new H/U and bought all the gubbins...ISO adapter, aerial adapter/boost etc and off we went. Easy peasy. Got out of the car, went to lock the door and nothing, sod all, zip, bugger all!! WTF is wrong with these VW's.....Unplugged it all and hey presto, it is all back.
Strange to say the least.
If i don't use the ISO adapter and swap the wires, yellow/red...red/yellow, the stereo doesn't even work. Old Sony XPlod just in case it makes a difference.
