Hi to all!

I have the x910bt that I purchased used with the bypass already installed. Everything works great except when I place a call no one can hear me. I have replaced the mics twice with brand new ones...still doesn't work. I've searched all over the web for answers to no avail.The mute/input guide is grayed out if that helps. Thanks in advance to anyone that can chime in. 

No one has any suggestions? I guess not

I have a X950BH model, not the same as yours of course but when I bought it I asked about using a blue tooth or wireless mic and the owner of the shop told me they don't generally work. I was not crazy about having to run additional wires around in the dash but he said the "wired" mic came with the unit for a good reason.....it always worked!
