3.4 Antenna Connections

The TranzIt BLU HF connects inline with your vehicle's FM antenna. Disconnect the vehicle's antenna from the radio and connect it to the TranzIt BLU HF's antenna input. Then, connect the TranzIt BLU HF's antenna output to your radio's antenna input. This setup allows the device to interrupt the FM signal for Bluetooth audio.

3.6 Microphone Placement

Position the external microphone in a location that provides clear audio pickup for hands-free calling, such as near the sun visor or on the A-pillar. Route the microphone cable discreetly to the main unit.
