I got a Blackvue 750s with the Power Module. Its installed, however the parking mode isn't working. If the car isn't running, the unit has no power and I am baffled.

The Yellow wire is the +12v battery wire. I test the fuses and I am getting +12.22v at the wire.
The Red wire is the accessory wire, the fuse tests +12.22v with ignition ON.
If the car isn't running, the unit has no power and turns itself OFF. I'm completely at wits end. I'm receiving power, so why isn't it staying on? The power module's light and ON/OFF switch don't work with the car not running.

When I probe the cigarette lighter female end, it reads 2.3v with the DMM. Is it somehow not getting enough voltage to power up?
Anybody else wired in the blackvue?
