Adding CarPlay to 981 Cayman - options

Hi all,

I've been looking at the various options for adding Carplay to my Cayman to replace the CDR-31 base unit.
I've considered the various add-on boxes from JoyeAuto, NMAutomotive and the various similar units on Alibaba and have nearly purchased a JoyeAuto unit several times, but whilst I like the idea of preserving the OEM look, I'm also now drawn to some of the Android head units out there.

I've looked at Xtrons and checked with them, but unfortunately they don't have a unit which will fit the 981 and have no plans to make one. Same goes for Dynavin.

Have also seen other options like this pricey one from Belsee but not convinced it will fit the 981:

This one caught my eye recently as it also has physical knobs which I like, better screen and supposedly much more modern internals. Of course there's always the chance that this will turn out to be a piece of **** with zero support from the manufacturer, and set fire to my car, but at only about £180 on eBay I figured it might be worth a shot :

Not being a car audio expert I'm not sure what wiring adapters or other splicing work might be required to fit this unit - here's an image of the rear showing all connections - can anyone tell me how easy difficult fitting might be in terms of wiring?.

Any other options that I've missed for adding Carplay to the 981?

Thanks!
