They used to have a Tesla style model for the Px1. but seems its gone from their website.
I have their FG Falcon headunit (since its the only one on the market that can control the AC) and it works fine. I mostly just use Carplay with it. They are android headunits so they are pretty customisable and my Falcon one looks factory since it reuses the factory facia. if this PX1 unit is anything like the falcon one I have, it should be almost completely plug and play since it was designed specifically for this vehicle.
This is the one they used to have which looks cool imo.
