I think most people here are underestimating what it really takes to get a Tesla style screen.
Remember, these companies have teams (probably with 10 or more people) designing the head units. It probably takes a full year to get the user interface done alone.
There was one guy who was trying to get it up:
Tesla styled screen setup
but the programming and raw material sourcing was the issue.
I was in talks with another guy at a time to develop the bezel for his system, but that never took off either.
Like the guys above said, just get a tablet that fits and make a custom bracket.
I used the Samsung Galaxy Tab S2 8.0 and designed my own bracket. I thought about selling the bracket, but never got definitive answers from the Mods to sell for a short time, so never bothered with it. I'd probably have to think about designing around another tablet too since the Tab S2 8.0 will probably have an EOL soon.
But don't underestimate the process these manufacturers spend to even get their own set-up done. Even if it still sucks, like the stock navigation lol.
