To pair your OBD2 scanner, you’ll need a few essential items:

A compatible OBD2 scanner (Bluetooth or Wi-Fi enabled)
An Android head unit with Bluetooth or Wi-Fi connectivity
An OBD2 software app compatible with your head unit (e.g., Torque Pro, Car Scanner ELM OBD2)
A basic understanding of your Android head unit’s settings
