I have the Z2, bypassed and with Toomey's HD/software updates (works great by the way).

Unit has worked perfectly until now when the voice operation function stopped.

The voice icon appears in the upper right hand corner of the screen. When I press it I get the "Please request voice command" message at the bottom of the screen as well as through the speaker.

But when I give it a command it does nothing, as if the microphone is broken or disconnected.

After a few seconds I get the voice command, "Please press voice command key to continue".

I press the voice command key and give it a command and again nothing happens.

Any suggestions other than check the microphone. I'm hoping one of you has a simple suggestions so that I don't have to tear the HU and microphone out.

Thanks in advance for any suggestions.

Def sounds like a Mic problem...

Most usually plugged into the wrong port or just not plugged in completely...

But the mic could be broke... otherwise, probably not your HU and just the MIC....

Turned out only to be a short in the mic wire
