I got an ORKSEY (cheap but well reviewed from Amazon UK) in a 2013 Prius and it works well. Dealer wired it in for me and it's pretty smooth. The camera on the back came unstuck a few times but I now have it taped onto the plastic trim. Very happy with it, but haven't had to look up any footage yet. https://www.amazon.com/gp/product/B07PFSXZ2W
