Hello all, new member here. Just wanted to stop by and show how I hard-wired a front-facing dashcam in my wife's new Equinox. I know there's an adapter you can get for some rearview mirrors, but I already had the wiring kit, and I didn't see any threads about alternatives, so I figured I'd share.
I don't have park mode enabled, so I only needed a switched 12v that shuts off when the car is off, but all of the existing fuses are all 12v constant power. After poking around, I found that there is an unused/empty slot (at least it is on mine) that does have contacts inside that just happened to be switched power, so I just tapped into that.

And there is a convenient ground right nearby to the left of the fusebox. I don't know the thread type, but I happened to have a nut in my parts bin that fit.

All wired up

Running the wires was easy; just pull the rubber door seal back and run the wire up the pillar, across the top of the windshield, and tucked under the roof liner. Just make sure the wire is behind the airbags in the A-pillar. It's a little easier to run up the A-pillar if you pop the top of the trim piece a little. Then snap back in once done. Easy peasy.
Then, I zip-tied all the excess wires together and tucked them down behind the foot panel (near the ground lug).
Hope this helps someone!
