Arpha E21 Model 1080P Mirror Dash Cam Unboxing, Install, & Review! Easy To Install! App Doesn't Work

Very helpful video thanks ,
But how do you turn the mirror on all the time .my keeps going off

What is the name of the GPS/Wifi you have in the demonstration?

Thank you for your response. It was very helpful. I have another question. Can you display both front and back cameras at the same time? If you can, can you show us how it is done? Dr. Mbobi
