I have the Avic Z2 and had the bluetooth hooked up as well, the problem is that when I talk on my bluetooth, the person who is talking hears their voice echooing but on my end it is clear and sounds good. Does anyone know or have the same problem? Thanks.

I have had the same problem

the microphone picks up everything in the cab of the vehicle, including them talking through the speakers

I have turned my radio mute on full, and the volume of the caller down and havent had any complaints in a while

Yeah its pretty bad, I installed it on my 05 Mustang GT and since I upgraded my mufflers I can't hardly talk to anyone! Damn mufflers, back to a bluebooth headset for me!

can this be fixed somehow

I fixed it by doing the following:

1) Buy the cheapest headphones you can find (the once with large ear pieces)

2) Take off the foam wrapping

3) Wrap that foam on your mic

The foam will remove a lot of noises. The drawback is that your mic will no longer be as sensitive.

Hope this helps.
