Today I find intressting Android Headunit for Leaf ZE1.
But will it lose functionals like app control temperature, battery, all round system?
i don"t know if I can put link.
I did dat on last car (Toyota IQ) with arduino and laptop with other software (CANHacker v2.00.02) that works with arduino uno and canbus shield.
Altough it is connected on OBD-2 to DB9 cable. (Canbus shield has db9 port)
And software and code you can find is here...
