2019/ 2016 Headunit

Could the head unit of a 2019 (with Apple CarPlay) fit and work in a 2016? While the dimensions look the same, I’m guessing they may have changed the wiring in the back?

 

I believe you’re asking about a 2020 head unit compatibility with earlier models and no one has done it yet. They’re a couple grand, so you can find out if you can fork over some cash

 

OH OK let me just put it on my platinum card! Haha.

 

I believe there’s more to it than just buying a 2020 OEM head unit and doing a swap to the 2019 and previous years. The pin connections on the wire harness needs to re-pinned, which can be a great deal of work.

Watch this YT video where it’s better explained. It’s for the Tundra but probably applies to the 4Runner as well.
