I’m installing a dash cam, and for the time being I want to use the media port on the center stack. Later on I’ll probably hard wire it to an ignition switched source, but to get it going now I’m using the USB 2.0 (not C) port. I have the option to use the cigarette lighter, which is switched using ignition logic (no power supplied when not in run/ Acc), but I’d rather use the media port behind the square door to keep the plug out of the way of my knee.
Does anyone know what its power schedule and logic is? I plugged in the camera, and it remained on for roughly 3 minutes after turning the ignition off, then turned back on after 30 seconds. When exiting the vehicle, locking, and checking on it 10 minutes later it was off, but turned back on again once the door was opened. Also, is the CanBUS smart enough to shut down the ports when battery voltage drops below a certain level like it does with interior lights (if switch is left commanded on)?
Points of concern are:
I want the camera to be hands free. Turns on when preparing to drive, turns off when not in vehicle with no action by me.
I don’t want it receiving power constantly. It’s a Garmin Mini 2, and for some reason it gets and stays hot….which means it’s using significant power. Not good if left on for days at a time on the battery. (Garmin says it getting hot is “normal” operation)
If it does stay on, as in the port never gets turned off by the vehicles logic, will the JL ‘protect’ itself by isolating that usb port as it does with lighting when the battery gets below a preset voltage?
It seems the center console “USB 2” port follows the same logic, as I use that for CarPlay, and have seen similar behavior. I’ve also tried to charge my phone with it overnight with it taking power after plugging it in (vehicle never put in run) only to find it not supplying power in the morning with a dead phone.
