Is there 2 microphones? 1 for bluetooth and 1 for voice recognition? i have a bluetooth adapter and i connected the mic so i can make calls and what not, but i cant figure out how to use voice recognition? do i need another mic for that?

same mic for both.

If your MIC is connected properly on the Z1/Z2, you should see a face )) icon on most screens. Press that and your into voice recognition. Consult manual for available phrases etc. If you don't have that icon, then it would seem your MIC is not hooked up properly.
