Since there is only vague support for the chevrolet volt gen1 car, i use the most promising box from raize. There are several issues, main issue is that the panel buttons include the volume knob is not working. Possibility is proofed by using a hiworld canbus adapter with which the panel buttons and volume knob is working. I will not use the hiworld because the other functions are less good working (nearly nothing) then with the raize box.
