Audi Dash Cam & Radar Hard Wire

I like to hard wire devices to my cars, especially for daily use. I get super annoyed at cords everywhere and think it’s sloppy. I decided to hard wire my Audi dash cam and radar detector.

Audi Dash Cam: Street Guardian SG9665GC v3 2017 Edition

I chose the [amazon_textlink asin=’B00U0OJMYG’ text=’Street Guardian SG9665GC v3 2017 Edition’ template=’ProductLink’ store=’dovidenko-20′ marketplace=’US’ link_id=’d529ee31-6b50-11e7-b455-3584eb6d2710′] because it had the clearest looking night time video and I liked the form factor. For my Audi dash cam needs I knew ahead of time I would be hard wiring it. So I also purchased a few other things:

  • 12V to 5V Transformer – Because the car has 12V power and the dash cam will need 5V
  • [amazon_textlink asin=’B01860VMHK’ text=’3M Double Sided┬áPads’ template=’ProductLink’ store=’dovidenko-20′ marketplace=’US’ link_id=’decb8e1d-6b4f-11e7-8e8e-57bb2eb7ab00′] – To mount the radar detector. Dash cam came with sticky pads which are nicer.
  • [amazon_textlink asin=’B01I1XF4XU’ text=’MirrorTap MTX RJ11 Tap’ template=’ProductLink’ store=’dovidenko-20′ marketplace=’US’ link_id=’077a4a25-6b50-11e7-8567-69c69afd010d’] – Got this to go ahead and splice in the RJ11 connection for the radar detector.

The install came out really clean. I ran the wiring into the mirror housing where I spliced the switched 12V wire with the MirrorTap and used a screw for a ground. I had already soldered together a harness which fed off the MirrorTap. This harness included the 12V to 5V transformer so everything was plug and play past that.

The radar detector I use is the Escort Max 360 which is an excellent detector. I had to design and 3D print a mount for it, because it did not come with a mount that could be used with an adhesive. The mount was printed out of PETG and secured with some of the original hardware from the original Escort mount. This way things stayed pretty plug and play between mounts. The 3M double sided pads secured the mount to the windshield well. I have not experienced any problems thus far, except having to tighten the screw after the PETG heat cycled a few times in the hot car.
