I wish you would have app so it does not lock out phone functions. I try to make a call an im not able to punch in numbers on on phone. Instead while driving or stopped In traffic I got to fumble with vehicles functions to find a key pad then punch it in on dash. I HATE this very unsafe an annoying. Plus same goes for using Google maps know where on phone I need to go but got to play on cars functions to try to get info. Also u can't add if there's accidents or police speed traps
