With the note 2 this was a breeze headphone jack from phone out into the mercedes aux in and everything came through the car's audio system.
Easy and good sound for phone and music. without the aux hard wire the car's bluetooth worked well with the telephone calls and notifications
TODAY Note 3
If i use headphone jack out, then sound from apps hard wired into aux works well, but the phone calls will not re-direct thru bluetooth nor pass through the headphone jack out into the mercedes aux in.. this means i cannot hear the phone ring nor make nor hear in coming calls..
i am not all that tech savy. my current solution for driving alone is headset hard wired to headset. ....i like kilpsch. I have tried playing with the settings and cannot get everything to work as it did with the note 2 in the past.
I tried looking around and did not see a solution posted elsewhere.
