Why my car dvr can not do recording?

Pls check your TF memory card first, if TF card inside already have other dvr device video or picture, it can not be read by your car dvr device, you should format your TF card first, better use an empty TF card into your dvr device when you use first time.

Why my dvr display turn off automatically while driving ?

Usually dvr device will on standby status if you did not do any operation on it more than 1 minute, but it also keep on recording.
