Mk7 Golf 12v Aux Connections

[Poida]

Hi Guys,

I want to install a dash cam and wondering where or if there is 12v aux connections that are easily accessible in a golf mk7?

Cheers!

I ended up fitting a new fused USB port in the back of my glovebox. I then ran the USB cable around the headlining to the rear view mirror to power the Dashcam.

Do a search on dash cams I posted a big how to recently Cant remember but think it was in the Passat forum.

Get a fuse tap straight into the fuses and wiring that up. Your dash cam should potentially come with a 12v socket if not get one from eBay and it'll save you from wiring up to the 12v charger. I'll try and post a pic of my setup later

Poida: All good suggestions from OPs, but I suspect that the best solution depends on where you physically install the new dash-cam.

If you intend to place it high near the roof lining in the rear-view mirror area , then you could tap into the switched +12 V wire for the mirror. Given the current draw from the dash cam is really small -perhaps consider installing a new in-line fuse. Or you could just take a chance and rely on the factory fuse to protect the dash-cam given that the VW fuse is rated @ 7.5 Amps.

You probably already know, but car fuses aren't really good @ protecting down stream components from overload, they are better @ short-circuit protection. Nevertheless, the size of the fuse that's used does determine how much energy the fuse will allow into a fault and therefore how much potential damage will result in this instance. Too large a fuse size and you might as well just use a nail as a fuse - too small a fuse size and you will be constantly replacing the fuse (it's a compromise)! If you do install a new in-line fuse, remember the rule-of-thumb for grading series connected fuses: The down-stream fuse should have a rating of no more than 50% of the up-stream fuse.

Here's the wiring diagram showing the connections to the anti-dazzle mirror : note the +12V wire

Thanks Don. I might use that to clean up my install!

I gave VW feedback on actually putting a USB port on the back of the mirror.

Cheers Don,

The mirror option sounds like the best solution, thanks for the wiring diagram.

Thanks for the other suggestions guys!

Just be careful because some Dashcams that use a USB supply actually run off 5V and they will get smoky if you hook them up to 12
