Probably the first thing that anyone stepping into a Tesla Model 3 will notice is its apparent lack of dashboard controls — there is literally nothing on the dash whatsoever, except for this 15 in touchscreen. Once activated, the touchscreen is the brains of virtually every vehicle system. Everything from the GPS navigation to the glove box release happens through this interface. In its review of the device, Cars.com noted its "crisp, clear graphics" with "the high-quality appearance of an Apple iPad," and "iOS-like onscreen menus" to reinforce that impression.
The following is an overview of a teardown analysis conducted by IHS Technology Teardown Services.
