-Found in many Nissan vehicles, including the Xterra, Rogue, Sentra, Altima, and other models from 2015 onward. It is possible to root these head units by probing ports, installing firmware through a USB drive, and using a USB to Ethernet adapter to actually interface with it. Further EOP functions are unknown, but may benefit from further probing and research.

It is possible to root the head units found in these cars by probing ports, installing firmware through a USB drive, and using a USB to Ethernet adapter to actually interface with the now-rooted Linux instance. Further EOP functions are unknown, but knowledge of potential EOPs may improve from further probing and research. The linked pages are primarily a documentation of experimenting on a head unit.

 === Windows CE access + Media ===
-This one doesn't run Android Auto. Linked video demonstrates a movie playing on the Tuscon's entertainment system, apparently on the "WolfNCU" movie player.
+One of many cars featuring a head unit that runs Windows CE. There are a variety of rituals and procedures required to gain access to the Windows CE sublayer of the head unit, but it can be done. Many Hyundai cars from this era run the same sort of software and presumably can all be "victims" of this sort of exploit.

-While it varies for each Hyundai, it is possible to enter a Windows CE shell on the infotainment systems built in. This redditor demonstrated this for his Veloster, showing off Windows CE’s solitaire, DOOM, and a Game Boy emulator. Presumably, other things are possible within the preexisting CE environment, which appears to be CE Embedded 6.0 as in the 2013 Velosters.

One has to wonder what sort of apps are in that folder... although realistically, it's probably something for the dealerships.

 === Doom (on custom Android) ===
-The video below is on a custom infotainment system, rather than the stock system included in the Mercedes (to my understanding); not sure as to how much was altered, but this is ultimately Android Doom running on a Benz infotainment system, albeit a non-stock one.
+The example here is a stretch, as the head unit being used here is an aftermarket head unit, which presumably runs some flavor of Android Auto which this person subsequently hacked. Nonetheless, it is a very interesting Doom port that actually uses the controls of the car itself to move the Doom guy around. Don't play this while driving...

The Model 3’s Intel MCU is known to be a lot more locked down, so this being done is somewhat of an achievement compared to other Tesla systems.
