Hi guys,
I just bought a Junsun V1 Pro Android head unit from Aliexpress and of course it has some issues. The unit came with a CAMBUS decoder for my car but it seems it does not detect the reverse mode, meaning the back-up camera / reverse camera cannot be activated. In this video I will show you how I managed to bypass the canbus and trigger the reverse camera mode.
