2006 VW Golf

they can be hard to get apart but i will try to explain it to you

under the top panel of the dash there are 4 torx bit screws remove them and then the top section will come out but watch the vents as they are hard to get out as you have to pull them towards you and the clips are unforgiving

the secion around the deck will clip off and the deck is screwed in

the deck is can bus so there is constant and earth there and there is mute althought there is no wire in the plug so all you have to do is use the centre pin from an fme antenna plug and plug it into the pin that is shown on the diagram on top of the deck

accessories can be picked up at the acc socket below the deck
