Control button/Microphone 

10.

 

Consider where to install control/microphone button. Keep in mind 
control button must be within reach and facing driver for voice 
commands and phone dialog (cable is 6ft. long). 

We recommend 

completing the rest of the install prior to securing the 
control/mic button to the dash. 

Once you decide on a location simply

 

remove tape backing from control /mic button 

 

Ensure no ventilation duct is pointed towards the mic. 
It is best to mount button facing driver
