I never was able to make my Motorola Bluetooth to work. On Droid DNA or on G2. You may try to install apk from your Bluetooth manufacturer if they have one. As for mine, i don't like what they offer. To use Google Now, you should stark it manualy only as far as i know.
- LG G2 (Verizon, CLEAN ROM 1.0) - Best one!!!
- Amazon's Kindle Fire HD 7 (CM, root)
- Samsung Galaxy S4 (i9500) - Stock.
- AT&T Galaxy Note 2 (Jedi ROM).
