Understanding OBD2 and In-Dash Touch Screens
OBD2, or On-Board Diagnostics II, is a standardized system that allows access to a vehicle’s diagnostic data. It’s the port mechanics use to diagnose your car’s problems. An in-dash touch screen, typically part of a modern car’s infotainment system, provides a central interface for controlling various functions, including navigation, entertainment, and increasingly, vehicle diagnostics. Integrating these two systems offers a seamless way to monitor and interact with your car’s performance. You can even customize the display with information relevant to you.
