OBD2 doesn't have audio in. It does have power out, which would be one reason to connect to it. On the other hand, there's one little problem - it's going to be illegal in an ever increasing number of states. In CA and the aforementioned increasing number of states, you may not use your cell phone while your engine is on unless you can do so hands-free. This unit does not qualify.The point is that this is 100% wireless for clueless types like myself. :lol: Because fuck electrical work (despite how easy it likely is). Also, I suspect the in vehicle module maybe has a speaker or something in it too?
