The OBD II Device provides meaningful data about your vehicles such as road, speed, location, and much more. The OBD Port is where you can plug in any OBD tool into the vehicle to pull the vehicle information. It is also the primary location of tracking devices as the port provides ongoing power to the OBD II device.
The OBD II device is a portable unit that plugs into the port by the driver. No need for professional installation.
