Looking for front camera with backup camera/display

My work car (2016 Ford C-Max Energi) has an obstructed rear window (full wrap) and I'm in need of a backup camera. Since I drive a lot, figured a dashcam would be good to have as well. Since it's a work car I don't want to spend too much, but I do have the ability and would semi-permanent mount it. Since the rear window has a wrap, would like something with a camera I can mount outside the car.

Prefer a wedge shape and not a replacement mirror, display size is not a huge factor, turning on with car power would be great, prefer to download (if needed) files from a card opposed to wifi. Just needs to be easy to switch the inside display to the rear camera. Figure IR on the outside/rear-view camera would be helpful.

I saw the SG9663DC and it looks great, but $500 is a bit more than I want to spend. I have also seen PRUVEEO Q2 (is it good for $60?), Rexing S500 Pro (not sure I like the way it looks), Rexing V1P (looks nice!), ITRUE X6D (looks like the Rexing but comes with card and hard wire kit). The more I look, the more I see these are not really backup cameras since the video would probably be upside down.

Thanks for any input!
