Is there any way to change the mics out. Meaning use a better mic with the Z1? Or will the ports not match up? I know the sound quality on mine is terrible and I have moved it every where and changed the volume as well. Thanks for the help.

Does the mic come with the Z1 or the bluetooth adapter? Or is it a separate purchase altogether?

The mic comes with the Z1 unit.

The ic also has a sub-mini connector - reasonably hard to come by. DO NOT USE the usual sub-mini to mini adapter (a la' radio shack) as it doesn't seat fully in the connector on the rear of the HU and will fry stuff. I know this firsthand, as I tried to use one to hook a speaker to the External NAV Speaker connection and screwed up my unit...
