Alright I can't post a detailed guide yet it's getting late, and I have a trip this weekend.
Basically you can use the dirtc0w exploit found here, https://github.com/timwr/CVE-2016-5195
. You'll get I/O error, but it still works for some reason. After that, you should get to privelaged shell using the run-as command. From here on just edit the whitelist found in /data/data. It's labeled "whitelist-1.0.xml". This can be done the exact same way as the pilot so it was fairly easy. After the whitelist is edited just install the APK from a usb (make sure you use the usb port in the middle of the car, underneath the cups).
