The following is an overview of a teardown analysis conducted by TechInsights.

Automotive infotainment has come a long way from analog controls — buttons and dials for commanding systems such as radio, climate and car controls.

Today, many cars feature touchscreen displays for radio and climate controls and digital control over car functions via touchscreen or heads-up displays. There are more innovations coming as well including the introduction of augmented reality into vehicles and the ability to control infotainment for passengers.

These infotainment options are designed to improve the experience for passengers by providing movies, custom music options and even video games. While many of these functions are not there yet, they are coming soon and automotive OEMs are already developing the touchscreen displays and infotainment systems to support these future innovations.

Mercedes-Benz A Class center stack for infotainment systems is a dual touchscreen display for vehicles that includes a variety of electronic components including field programmable gate array (FPGA) from Xilinx, 32 bit MCUs from NXP Semiconductors, memory, LED drivers and more.
