2. Choose a proper mounting location for the microphone, most customers mount near rear view mirror or
area in front of gauge cluster. Avoid mounting the microphone by the side windows to eliminate extra noise.
Please also avoid mounting behind visor to avoid blocking voice from reaching the microphone. Carefully
route the microphone cable down into the dash where the GROM-BTD is installed. Connect the microphone to
the female audio plug on the GROM-BTD. Make sure the mic is connected securely and all the way into
the 3.5mm port (see picture below).

player connected via AUX cable, you will have to turn it off manually.
You don’t have to disconnect the USB drive or Android phone since it will be automatically muted once
