deos not have a screen
activating adas = after installing the cam. you need to connect the phone to the cam via usb. not wifi. to install the app from the device it self. after installing the app you have to update app to get the adas option... over all nice device but not easy to configure...
You will capture all clear and clear images. The design is much better than my previous driving recorder, and I can hide it without letting the bulky screen face me. very good.
