This is really cool. It's an OBD II compliant device from Bafx Products that uses a Bluetooth connection to your cellphone to retrieve vehicle OBD computer codes. You can easily find an app called Torque Pro in the Google store for your phone and it's good. Especially if you have a diesel and it will tell you all pertinent data like fuel and HPOP pressure and everything.
Funny how people say today's vehicles are unfixable yet its never been easier.
