With my LG Nexus 5 with Android operating system everything works fine:
Once I start the ignition, the Kinivo connects automatically and without any further action with my smartphone.
Simply pressing the multifunction button then starts the music player of your smartphone and using the forward and back buttons I can quite easily zap through my playlist.
If a call, simply press again and release the multifunction button and you can hear the caller through the car speakers. The audio quality on both sides is very good.
Last but not least the Kinivo also supports the Google Now Wizard my Nexus 5:
Simply press 2 sec. On the multifunction button and you can enter a short Bestätigungsbeep his desire or his question and gets then recited the answer.
Even the call to a contact (Language selection) works about perfect.
The Kinivo really met all my expectations: I can finally listen to music from your phone, take calls and also make and all that without that I have to take the phone even once in the hand.
