android mirror wiring help

Hi Explorers

I bought this android mirror for a backup camera project




i know how to wire the camera but i need help to wire 12v for the mirror because it will keep work while driving for navigation, i thought about tacking power from roof interior lamps but they don't switch off after ignition off << i'm talking about the manual switching lamps not the auto ones.

i need a power source that disconnect after ignition off

any ideas how ?

The radio would have a source for 12V+ Switched. You'll just have to run a power wire from it, through the dash, up the pillar, through the headliner, to the mirror.
