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
