BMW E46 Android head unit
A little context:
I have a head unit, that I want to have constant power through ACC. Basically, it's an android tablet customized for my car, but the manufacturer (unbranded Chinese) did not take into account that android tablets are actually never supposed to be fully powered down. Therefore, I'm well down the road before the unit is ready to go.
How can I wire the ACC to always have power? Is it as simple as jumping the yellow and red wires like I do when I run my unit off of a PC power supply? I just want to make sure that is safe for the car, I know that might sound a bit stupid. Car wiring is foreign to me and I want to make sure I know all of the dangers before I fry a very expensive competent in my very expensive to maintain German vehicle.
What I think I already know:
I understand that by constantly leaving the radio powered it will drain the battery, Having done some tests on the bench; I think this will be negligible as I am able to put the device into a hibernate state. If draining the battery is the big risk then I'm not too concerned about that.
