If anyone can help i just finished installing my new avic, but i am getting no audio on bt or voice guidance from the nav. all other sources are working, and people can hear me on the bluetooth

What kind of car? What adaptors were used to install it?

You only hear navi voice guidance and bluetooth phone calls output from the front RCA outputs or front speaker level outputs of any Pioneer navi unit.

To test,play audio from the AM/FM tuner and fade your music all the way to the front, if you lose your front audio, then your not wired up correctly.Or your using just the rear outputs.(Dodge can- bus adapters)

If your using amps check to make sure all the amp settings are correct(2ch,4ch,5ch.6ch)
