When I turn off the engine (and the AIO6 at the same time), when I turn the PackTalk Edge back on, it won't reconnect, sometimes interrupting the music playback; I can't set up the driver-passenger system correctly to talk and hear the music. If I do it via iPhone, everything works, including voice commands. If I switch between the TFT and the AIO6, it works at times, disconnects, or only plays the music. A disaster for all the money spent.
