Yep I wanted the BT otherwise I would have just got the cable. I want to leave the interface as part of the car 24/7. Eventually I'll add an Android stereo with touch screen. End goal to have stuff displayed on it. Transmission temp for starters. Aldldroid, well so far it's one of the few things I've been able to get working. Can't get TunerPro to connect for love nor money so far. This is all very new to me. I'm learning as I go and very slowly so far. .-.-.
