I have been using Previous model Roidmi 2S and it has been very impressive so far except built in microphone. This newest model is compatible with all cars and has some new features like battery monitor, Navigation broadcast. Previous Roidmi models have poor built in microphone. I have to scream most of the times during a phone call. I hope this microphone problem is fixed in this version.
