For those who absolutely want CarPlay / Android auto, there are 2 solutions. The first one is the above, which seems like a decent offer for 40-50 euros.

You connect the box to a Tesla's type-c and pair it with your phone, just like in a regular CarPlay / Android auto. Once the pair is done, you go to the Tesla's WiFi, connect to the carlinkit's WiFi, and open the car's browser on tespush.com. That's it. Practically, you see the carlinkit's interface from the car's browser. It's a nice idea that is not as complicated as it sounds.

It works without any problem, it's responsive, the sound quality doesn't seem to drop, it doesn't lose connection, and all compatible applications work without any issue.

Until we learn the new tricks and Musk enriches the applications that a Tesla has, carlinkit is a very good solution.
