Switched power for head Unit on Golf MK6

[Timmos1974]

Hi guys

Possibly an easy question to answer but I am trying to install an aftermarket head unit to my sons Golf MK 6 and on the original wiring harness I cannot find any switched current.......so the radio is constantly on.


Do I need to find a switched supply from the fuse to go to the red wire?

Thanks i tried uploading a photo but failed dismally.

Normally with an aftermarket headunit the permanent and switched live have bullet connectors on them to allow you to switch the wires round. Try this first

Thankd for the reply.

When i get to test the harness in the car, I cannot find at all the switched current always stays on.

I believe on the MK6 Golf there isn't any switched live in the harness, it uses the CanBus to switch on and off.. If your new headunit doesn't have a CanBus interface you either need to use an adaptor or take a feed from the fuse box. The 12V power socket (cigar lighter) is switched but I understand that when the ignition is off it still has some residual voltage so that be used otherwise the battery will drain.
