What changed in post 2019 4runners with the radio?

What exactly did Toyota change in the 2020+ 4Runner’s radio to where there are no aftermarket harnesses,radios, etc. compatible?

As of right now you can’t put a Halo 9 in anything post 2019 trims. What gives?

The long and short is that they went from Entune 2.0 to Entune 3.0; the headunits are equipped with cellular transceivers for automatic updates and the are tied into the SOS system that comes stock on 5th gens. This complicates the wiring and expands the total number of systems tied to the entertainment unit (for example, on pretty much all the Toyotas now with SOS, the microphone input passes through the DCM [Data Communication Module] before making it to the headunit, so an issue with the DCM could cause an issue where you're not heard on phone calls via Bluetooth.)

I imagine the smaller number of patch cables & aftermarket harnesses is more due to that added complexity. But I imagine that the aftermarket will address it going forward.

So you didn't read any of the thread I posted, did you? You really have no idea what you're talking about. The Maestro unit not only fully integrates ALL factory functions into an aftermarket heat unit, it has significantly expanded reporting and customizations. The *only* thing that is lacking is a USB patch cable, as noted above.

Stick to the 4th gen forum, sport.

No idea what you're talking about. I have a complete aftermarket system in my '20. The only things that are not available are the dash kit and a USB adapter. You can modify a Scosche dash kit to work but it's not easy. And you can run a separate USB port. See my full thread:

Is there a reason as to why a new dash kit is needed? Like why you couldn't connect the Pioneer radio you have to the stock dash kit? Is the original dash kit in a 2020 model not a double din size opening?

But yes, I just noticed the Maestro RR2, RT03, and UT03. Looks like it's those things for a Halo 9 and 11, both of which I was looking at. Then "wire wise" you're all set. Then it just comes to the dash kit.

Is the reason as to why Crutchfield has no recommendation for changing anything because of no dash kit and/or no harness on their site (which is a lie because there is) or because of certain electrical issues? Seems like last year I did the chat thing on their website and they said it was because there's no harness. But it seems there is so it's weird they're not carrying it.
