I can tell you from my personal experience that the USB charging power shuts off when the ignition is off. I had hoped to use the usb to charge my phone while the car is parked, but alas, no power when switch is off.
I can tell you from my personal experience that the USB charging power shuts off when the ignition is off. I had hoped to use the usb to charge my phone while the car is parked, but alas, no power when switch is off.I have a question I can't find an answer to in the manual:
If I leave an iPod plugged in to the USB port, will it cause a parasitic drain to the car's battery when the car is shut off?
That is true, but I wanted to hide the cord and not use the 12v outlet.I can tell you that if you have a USB charger to plug into the cigarette lighter, that WILL charge your phone while the car is off.
