Yes I have the little pioneer black box connected but even then the Icon on the very right/upper corner shows a Red X on top of the iphone image..

I try every screen/every setting, nothing changes..

Do I have a bad module...??

s it a Iphone setting problem, no clue..

Any other way to connect the Iphone to the Avic.. ??

I am having similar issue... Galaxy S7 pairs with unit fine and I can hear everyone calling.  They cannot hear me however.  I believe it may be a Bluetooth issue with newer Bluetooth version on the phone????  Any help is appreciated.  I've tried on a few phones in my house and when I pair a new one, the person calling me the first time hears me respond HELLO, but then the unit sort of "pops" a sound out and then they cannot hear me anymore.
