2016 Rx-350 F-Sport

Hi yall. I have decided to keep my Rx-350 after my last post. It was very encouraging and confirming how reliable these SUVs are. Now, mine has 12.3” head unit and Mark Levinson package. How can I modernize the headunit? I’d love to add some Apple CarPlay but keep it looking stock and to improve the backup camera resolution! It is very grainy! Has anyone done any of these upgrades and still reliable after years of usage? I fear to install a cheap Chinese hardware and to be glitchy and then have to dismantle everything once again! Any suggestions!

Thanks
