USB Voltage

Just a quick one guys.
Is there any voltage at the rear view mirror usb outlet when Power is off.
To facilitate dashcam parking mode

No. If you do a search on here, I am sure someone has detailed hard wiring the dash cam to one of the fuses, via piggyback, that remains live.

It powers off with the car if using the connector by the mirror.

This is why you need to hardwire it for parked mode IIRC. Just search for 'USB' or 'dash cam', there are a good few hits on this question: MG ZS EV Dashcam Hardwire.

Would have been handy if they had made a menu in the settings to control if this was "always on" or only "On with ignition"

Maybe with a warning about flattening the battery too...

Yeah i remember in my previous car, i had dashcam that was "always on"

Never had the car not wanting to start, but after installing it, after some time i suddenly noticed that it would never do the "start/stop" at the lights as it had done previously.

Looking in the manual, there were a number of reasons that this function could be inhibited, such as "Turbo hot", "Engine below a certain temperature", Climate control wanting heat to heat up the cabin.

But one inhibitor i had not known about was "Battery state of charge below 80%"

After moving the camera to the switched live, the car began doing the stop/start again, and this is how i found that the camera actually drew quite some energy over the hours and days, when the car was parked up, just merrily sucking away at the battery.

[ Edited Coulomb: quite some power → quite some energy ]
