It is important to know that the DriveCam 76 is actually listed on the company's site in the DriveSmart series. Only one version of the 7-inch DriveSmart has a dash cam and has the DriveCam appellation. Without the jumper, its $150 less. The 5 , 6- and 8 model is limited to navigation.
The class of 7-inch is the size of the unit (they measures 697 inches wide by 417 inches high by 1.38 inches deep) and the size of the display (695 inches diagonally) and the size of the class that is known as 7-inch. The screen in question is 1024600 pixels, so this is hardly Retina, but it was utterly pixelated by testing and a very good viewing panel. Found it very responsive to the touch, which isn't always given to musicians or workmen calloused fingers.
The camera is 30 frames per second, 1080p (for the best of our views between quality and storage) with a field of view of 140 degrees. The Garmin X86 (and the Garmin Yvonne) battery, is worth a lot of money. It allows the unit to record a video for up to a half hour when off without external power. Yes, we all have phones today, but you're never told. Our DriveCam 76 arrived with a 16-GB SD card installed. There are two card slots on the back of the unit, but it's only the one on the right as the camera looks like you are facing it. Some are for extra maps, but that does not increase the 16GB of data already allocated for the maps, etc. Also on the back are the power button and the type-C charging port.
