This device is simply a convenience option to bootmod3 users and carries no additional functionality over the laptop based OBD Agent.
OBD Agent device connects via OBD ENET cable to your vehicle's OBD port and connects over WIFI to a 'bootmod3' WIFI network for internet access to the bootmod3 servers.
NOTE: Device on its own has no bootmod3 functionality. Appropriate bootmod3 license is required for a given vehicle. Laptop based OBD Agent software and the device have identical features.
