Samsung Galaxy Note 2... Text to Voice (read from stereo) works, but is annoying. As far as Voice to Text...you cannot speak to the stereo. It only allows 20 general "pre recorded" messages like, "see you at home", etc. If using samsung galaxy, I would recommend using the S Voice for hands free text sending. ***Here is the major downfall though... using bluetooth for media, whether you are streaming music or watching a video, there is a 7 second delay between when it starts on your phone and when it actually comes through the speakers. VERY ANNOYING! My Evo 4G worked flawlessly. So I wonder if going from Bluetooth 2.0 to 3.0 ...could be my problem.
