Unfortunately, [USER=17509]@xackley[/USER] is correct about Torque on IOS. I use OBDLink SX connected to an Android head unit which replaced my radio.
When the ignition is on is when I would be concerned with BT security and the OBD port. I work in IT and deal with penetration testing quite a bit. I'm just minimizing risk. Besides, it could conflict with my phone if I wanted to stream. The USB dongle gives me more flexibility and better security.
