Mr 12 Volt MMI box ..power feeds ..always live ?

As title suggests…are the dc front and rear camera 12volt feeds always live..L

I know I can multi meter them but car is in electrical bits so trying to avoid unnecessary power ups ..

I can't answer this question, but I read on another website that the Mr12v system will stay live until I lock the doors - is that right?

E89s shut down progressively various systems after the ignition is switched off..some circuits survive post door lock..eh water pump..

So pre door lock most systems ‘should’ shut down approx 2-20 minutes depend on the circuits..

Sometimes a system will go rougher and then that system won’t shut down..even with door lock.

It’s a complicated critter,,
