I installed the Hansshow 9 inch display into my 21 MSLR as despite owning it for a year, the lack of front display gave me the irrits. I have to say I love it.
It shows in addition to speed, a bunch of stuff including trip meter, odometer, SOC and distance remaining and it's right in front of you. I was going to buy the Mickey Mouse ears, but decided on this one due to it including apple CarPlay. The main benefit for me of CarPlay is for navigation. The Tesla rarely gets navigation requests the first time, mostly due to the poor voice recognition. CarPlay has better voice recognition for me, and it's smarter.
For example, requesting navigate to Tranmere tennis club using the Tesla gives you a few tennis clubs across Australia but not Tranmere. CarPlay given the same request asks if you want the Tranmere bowls and tennis club. Correct. It's smarter with matches that are not exact.
It's about $4-500 USD, so not cheap. And it's not easy to install in an Intel car. I got it done, but accessing that plug is a PITA. But I believe it's relatively easy to install in a Ryzen car as discussed previously.
My wife on the other hand was not bothered by the lack of centre display, so each to their own.
Now if only they had made a hatch instead of a boot, put lane change warning in the mirrors, 360 degree camera for parking and rear cross traffic alert, the car would be perfect. Now to convince my wife that the acceleration boost is an important safety feature. Pigs might fly.
