I use GPS Drive MotionX with an iPhone 5 and the Live Talk feature of MotionX will not work as soon as I start the car. The phone is connected by bluetooth in the Prius. Never had that problem with my old 2007 Prius. Does anybody know how to fix this?
Don't have an iPhone, but on my Android phone, I had the option of connecting the phone via bluetooth for any or all of three separate functions: phone, audio playback, data. Perhaps you are only connected for phone use?
