Power source for rear dashcam?

Op has a 4 door.

it’s not too bad, of a wire run, but if you want to run down the middle, you’ll need to drop the headliner, at least partially, which is a bit of a chore, l in order to get the wires run. There are parts of the roof that are otherwise impossible to get around.
I didn’t really want to run entirely on the side, due to airBags, and sometimes the wire falls out if too close to the trim, down the middle is more out of the way.

 

Sure it's not taped up that can't be seen? Also, do you have the fuse in the engine bay for the amp?

 

Thank you so much for the help and photos. But I ended up taking out all the side panels, undoing the rear passenger bolts on the front passenger seat, and using fish tape to get the dash cam power cable under the carpet. I then got it under the center console and plugged it into the USB port. I put everything back together and hid the wire behind the panels. I do realize this won't work with the parking function, but I'm okay with that.

Thanks again for the willingness to help. Also no fuse.

 

Does the added camera system have a feature to receive an view input? (reverse)

 

I can view each camera individually. Via the Garmin Drive app. But this is not a dedicated reverse camera. If that answers your question
