Can I use a head unit from newer Toyota Hilux etc

[azeeroth]

I have a 2009 Yaris with a double din stock radio. No bluetooth, no reversing camera. But it has the steering wheel controls.

If I buy a stock head unit from a newer Toyota with Bluetooth and AV in for reversing camera etc, will it work? Will the steering wheel controls work? I'm ok with building a simple harness if required.

Does it have to be a Yaris, or would a double din from a hilux, camry, etc have the same interface to the steering wheel controls?

There are people selling the stock units cheap when they upgrade theirs, I don't need better sound I just want bluetooth and maybe a reversing cam connector, plus the steering wheel controls to still work. My wife likes the streamline of a stock radio so I'm happy to upgrade that way.
