I finally got around with ordering a new dash camera and installing it on my recently purchased 2017 Cruze hatchback. I couldn't find too many threads about doing this so this will be somewhat of a guide.
So, the camera that I bought is "Rexing V1P 3rd Generation Dual 1080p Full HD Front and Rear 170 Degree Wide Angle Car Dash Cam". I'm not trying to sponsor them in any way, but I had one of their previous models for a couple years and I liked it so I went with one that has a front and rear camera. I figured because I got the hatchback that has somewhat of a good view out the back (partially vertical glass) that a rear camera would work as well. The front camera is the main unit and it has two USB wires coming out of it. One wire is for power and that goes to a cigarette outlet and the other USB cables goes to the rear camera.
I started with the fuse panel that is below the touchscreen unit. There's a handle on that piece of plastic and it pulls right out with just a bit of force.
The back of the panel shows what fuses go where.
I ended up using the 5 amp fuse to the right of that green 30 amp. The chart said that it was blank and I used a fuse tap to keep the 5 amp fuse on the line. I tested it to make sure that it was a "switched" power source. That is when the car is off that fuse is off. This prevents the camera from always running and killing the car battery. This also means the camera automatically turns on when the car turns on.
Here's something very similar to what I used when I say fuse tap.
To get a wire to this location I pulled off this side panel. Just give it a good tug and it will come off really easily because it uses metal clips.
Here's what it looks like with my wire ran.
I kept the stock dash camera wire that uses a cigarette lighter socket and added something very similar to this product.
I then grounded that socket on one of those two conveniently placed half inch bolts on that metal frame.
From there I ran the wire above the footwell carpet to the passenger door. I don't have any pictures of this process but I placed both of the wires under the rubber seal for the door. From what I could tell there was plenty of room after running the USB cable. The red line where I ran the power to the main unit. The green line is the USB cable running to the back of the car.
Again, the green line is the USB cable to the rear window.
And I don't have an image of me running the wire but I was able to pull that rubber hose out of both ends and then feed that USB cable though it. On the passenger side there is only 1 wire inside for the rear defrost so there's quite a bit of spare room. The other side has the rear washer line in it I believe.
From there it was just a matter of pulling off the back panels just enough to get the wire through it.
It got late, but here's where I mounted the main unit with double sided tape.
With GM's giant unit for lane assist behind the mirror I decided to go on the passenger side more. It's also important to get low enough that the front wiper blade covers the area in front of the camera. The same also applies for the rear camera.
Here's what it looks like from the driver's side. The screen turns off automatically after a bit. It's out of sight and out of mind.
That's about it. If anyone has any questions I'll definitely try and answer them.

Full disclaimer- probably don't do what I did. It's probably not safe by some automotive code or something.
