how to install accessory power to rear vision mirror area for dash cam

**mjgriffo** · 08-05-2016, 09:18 AM

Hi all,

I'm about to take delivery of our Mk7 GTI Performance, and will be moving our dash cams across from the Mk6.

Does anyone:

have any experience removing the Mk7 A pillar, or
have access to the technical drawings / eRWin instructions or similar?

I'm keen to avoid the complexity of the Mk6 debacle (anyone familiar will know what I'm talking about), however I'd also prefer to have that clean look without wires hanging everywhere.

Any help would be appreciated.

Regards,
Jamie

I did something similar to this: Installing a 2 channel Dash Cam - Blackvue DR650GW-2CH - VW Golf R MK7 Chat - VW R Owners Club

Depends on your dash cam, I suppose

I used a fuse-based USB socket from Jaycar to install a USB port behind the fuse box. I then ran a USB cable behind the trim on the end of the dashboard and the outside of the A Pillar trim (nearest the door). I did it by using my car upholstery thingy to pull back the trim just enough to tuck the cable in.

At the top of the A Pillar I ran the cable along the edge against the headlining and continued along the edge of the headlining and windscreen to the rear view mirror.

At the rear view mirror, the cable is tucked against the passenger side so you can't easily see it.

I use a 2m cable and this was the perfect length to keep the cable in place under its own strength and tension.

The USB port is on fuse position 47 (or it might be 4

and uses a 10A fuse which is then backed up by a 5A fuse in the USB port itself. It turns on and off with the car so I don't have to remember to turn it on when I get in.

All I had to do was take the end trim off the dash and drop the glovebox down to get to the fuse panel. I deliberately left the A Pillar trim alone because of the airbag behind it.

OK - I've not installed a dash-cam in my mk7, but if doing so just requires a connection to a Terminal 15 Voltage (i.e. volts-on when ignition-on) and earth, then the VW wiring diagram says that it's possible by thieving these points from PIN #1 (+12V - T15) and PIN #2 (Earth) on the antidazzle mirror. See below - what have I missed?
