I was just wondering the same thing for a 2013 Honda Civic - has the screen's (the "head unit"?) firmware been fully dumped and reverse engineered?

How realistic would it be to run fully custom firmware there, and even communicate over usb - for example, if I had a pi running in the car, and it used the usb connection to show things on the built-in display?

I'd love to pwn the head unit in my 2014 Honda CR-V just so I can stop it from sending a "Play" command every time a phone associates with the Bluetooth and the audio system was left "on".

I also have a 2014 CR-V and I hate this too. But even moreso, I hate that there isn't a play/pause button at all. If I need to stop audio (e.g. pulling up to a drivethru, or starting a conversation), I gotta hit the phone. Heaven forbid I'm playing a CD, nothing I can do at that point.

Putting up a bug bounty of "ordering you a pizza" if anyone tackles this!

I get pause (for Bluetooth playback, at least) by pushing the volume encoder knob. That works well for me.

Had a Chevy that was extremely obnoxious about this. If it was playing over USB it absolutely would not allow it to stop. Hitting pause on the phone would have the car immediately hit play to restart it.

It's probably easier to just buy an aftermarket head unit. The only thing you'll need to confirm is that it supports features you care about e.g. steering wheel controls.

Probably more difficult than hijacking the display with the pi. But that's just a vibe.
