It worked good a few years ago,but know with my galaxy S21 it won't work most of the time! Who knows what they did to ruin it but the damage is done. When it half way is working it still won't talk you thru your root,like take this exit go right ect.ect.ect.Not at all helpfull when your driving and can't look at your screen. Which now makes the app usless,and to make it even more angering you can't delete it. It use to be we own our devices.! Hey I paid for my devices google !
