Hi there!

I`m new here but have lot of experience in car audio though (but not with navi combo headunits) . My issue is: avic - f920bt is connected to permanent "+" to have ability to work when ignition is switched off. Everything is cool except for fact I CANT SWITCH HEADUNIT OFF ! Display is off but buttons are illuminated, fan is working ((( How come there is no big red button ON/OFF ???? Please, help! I don`t know what to do and my battery is dead every morning.

Why it doesn't have a power switch is irrelevant! The fact is it doesn't have one. Either install the unit as it should be or install a switch on the power wire.

Yeah. As I guess it`s the only way....
