Android head units look very interesting as long as I am not misundestanding something
Do those have native CAN bus on board? Can we access that CAN bus from java? does RealDash acccess CAN bus on AHU already?
Also some come with 4G connectivity which would make an AHU a perfect dual role “dash” and “telemetry access point” off the shelf hardware?
That all assuming we have a healthy reference hardware unit. My very limited read about AHU gives some random brand fears, is there a good brand/model one can recommend?
Pretty much copy-paste of my https://forum.xda-developers.com/t/eli5-canbus-android-development.4448965/ question
