Every time when the car is started (ie, the cigarette lighter port is powered on),the dash cam pro automatically boots up. The dash cam will turn off automatically when the vehicle is turned off (ie, the cigarette lighter port is powered off).Some vehicle's cigarette lighter keeps being powered on even when the vehicle has been turned off, in this situation, you need to manually turn off the dash cam pro. And the next time you start the vehicle, you need to manually turn on the dash cam.How to observe the running status of the dash cam pro?Check the status indicator on the side of the dash cam. If the indicator is green, the dash cam is recording normally;if the indicator turns red, it means that the recording is abnormal.What memory card does Gmai and NVNUVU Dash Cam support?Gmai Dash Cam and NVNUVU Dash Cam support standard Micro SD card (TF card) with the capacity of 16GB to 64GB and speed at Class10 or above.Make sure you use high-quality storage cards from a known brand.
