5 stars: Easy to use, when I drove, it reminded me to use voice message to stay safe, also it told me by the way, there is a voice message button on the steering wheel, very considerate. I really like the Bluetooth phone calls, it's very clear and safe, at the meantime, my cellphone was charging, never worry about consumption of battery. I like it very much, will use it every time I drive
5 stars: UPDATE: CHANGED MY RATING FROM 2 TO 5 ! Finally found an honest smartphone repairman. It turns out that these Samsung phones pick up lint in the charge port when in the pocket which then gets compacted by the USB plug until it doesn't go in far enough to make contact with all the pins. Phone then doesn't connect to car properly. Repair (port cleaning) was$ 10.
4 stars: COOLWALK COOLWALK COOLWALK! I have some small issues with music playback. Probably that I just don't know how to do it. Would love to be able to fast forward tracks as they are playing either by holding the next track button or a progress bar like in the YouTube music app. There are a surprising number of songs that start badly so when I hear a new song I like to jump forward a bit to skip the preamble... Maybe it's just me.
3 stars: This is a great start, with room for minor improvement. Wireless works well. When showing music and navigation I would prefer to have navigation on the left side, but that isn't currently an option. I also miss having stop signs, street lights, and speed traps marked on Google...
