Connecting your iPhone to this port allows you to access a wealth of information about your vehicle’s:

Engine Performance: Real-time data on RPM, speed, coolant temperature, and more.
Fuel Economy: Track your fuel consumption and identify areas for improvement.
Emissions Data: Monitor your car’s emissions output.
Diagnostic Trouble Codes (DTCs): Read and clear those pesky “check engine” lights.
