I soon plan to get a OBD2 bluetooth adapter and the Torque Pro app as well. You might be interested in that if you ever do any work on your car.
Let me know which adapter you end up buying. I've been thinking about getting one, but I understand the quality of the cheap ones is very hit-and-miss. Which one you get and how much you pay for it would be of interest to me (as well as it quality and reliability, of course!)
