I know there's a few videos on YouTube that outline fitting a dashcam to the Atto 3, I found that there were a few improvements to be made on the routing of the cable.
Follow the video until the point were they suggest prying back the door seal near the passenger airbag switch, but continue to route the cable inside the door seal past this until it's below the flap shown below.
At this point I would suggest turning that switch off while working in this area.
The panel to the right of that (the dashboard end panel) will pop open to allow the cable to easily be pushed up and through into the glovebox area.
Snap that panel shut again and loop the wire over the tubular cross member to keep it out the way
Drop it down the centre console and plug it into the BLUE socket next to the black socket.
Pop the panel back on.
The instructions on videos tell you to reboot..... I turned the car on and off countless times and still the dashcam didn't work!
What it should say is, press and hold this button to force the infotainment system to reboot!
Once the systems rebooted a couple of times,the dashcam app becomes enabled and camera functional.
You can now press and hold to change the function of this button....
So that it can be used in any emergency to lock the current dashcam clip, or to take a photo.
Hope this makes fitting easier for people. It took me longer because I was taking photos, but now I know the easy route - I reckon I could fit one in 20 minutes.
