Hi All. My 2015 CRV Touring has three USB ports and one “cigarette lighter” power supply in its center console, and one additional “cigarette lighter” power supply near the gear selector. For purposes of a dash cam’s “motion detection” feature I want to install, which (if any) of these ports provides continuous power; that is, supplies power to the plugged-in device even when the car is not running? And, any recommendations for a dash cam that records audio? Thank you!
