Installing a rear view camera, 2017 Mirage

[NickLund]

Hi, first post on here, so apologies if it's in the wrong forum.

I'm a new owner of a 2017 Mirage (or Space Star as it's called in Europe), fitted with the Apple CarPlay/Android Auto touch-screen radio. I'm fairly certain that the radio is the same as the one sold in the US, though an OEM rear-view camera isn't even an option you can buy here in Denmark. I am curious if it's possible to hook up an aftermarket camera to it.

My question is then, if any of the US owners with the rear-view camera installed knows how it's wired up, or if there is any pre-wiring run to the back. Or perhaps if anyone else have tried this? I can't find any information on it myself.

I did have the radio pulled out, and found a wire labeled "Parking", which wasn't hooked up to anything, along with a wire labeled "Reverse". Not sure where that one goes though. Also included some pictures of the wires running in the back. Pictures are here to not fill up the page:
