Re: Transfer Contax From Samsung Galaxy S4 To 2012 Nissan Bluetooth
Welcome to Android Central! Is the phone pairing in the first place? If it's pairing but the phonebook isn't transferring contacts, then make sure you haven't missed a notification on the phone asking you permission to allow the contact transfer.
If you don't see that, then open Contacts, tap Menu>Contacts to Display, and instead of All, select Customize. Now choose all of the contact groups you'd like display on the car. See if that works.
