Chapter 2 – General Installation
2.1 Installation location:
1. Connect the GROM-BTD 8 pin connector to the EXT1 port of the GROM-USB2P / IPD3 (AUX3) / MST3 interface.
Mount the GROM-BTD module away from metal structures in the dash and as close to the phone as possible.

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).
