Honda Pilot: HandsFreeLink System Description - Overview

The HandsFreeLink ^(R) (HFL) automatically connects (pairs) to a linked phone when the vehicle is in the ACCESSORY or ON mode.

The HFL also synchronizes with the paired cell phone's phone book to automatically update any changes. Depending on the functions of the cell phone, the automatic update may not work.

HandsFreeLink Control Unit

The audio unit or the audio-navigation unit has the HFL circuit and the Bluetooth transceiver. The HFL microphone in the roof console is connected directly to the audio unit or the audio-navigation unit. The HFL functions are controlled by the HFL switch.

The audio unit or the audio-navigation unit can check the HFL system components by the System Diagnostic Mode:

• Checks the connection between the audio/navigation system and the internal Bluetooth module (Display audio type).
• Checks the voice input level of the HFL microphone (Display audio type).
• Checks the status of the detection of the HFL switch.

• TALK Button: Activates the voice control system in the audio unit to accept voice commands.
• HANG-UP/BACK Button: Returns the display to the previous screen (similar function as the CANCEL button), or is used to end a call.
• PICK-UP Button: This button is used to answer incoming calls or to make outgoing calls. You can also go directly to the Phone screen by pressing this button.

General Operation

The HFL switch on the steering wheel is used to answer incoming calls, to make outgoing calls, or to end a call. The signal is sent to the audio unit or the audio-navigation unit.

The HFL microphone picks up the driver's voice, and sends a signal to the audio unit or the audio-navigation unit. The signal is then sent from the Bluetooth transceiver to the cell phone.

The caller's voice signal is sent from the cell phone to the Bluetooth transceiver. The audio unit or the audio-navigation unit outputs the voice signal through the front door speakers.

Muting Logic

When you are talking on the cell phone with the HFL system, the front speakers provide the HFL sound and the rear speakers are muted.

Fan Mute Operation (With Climate Control)

When the voice recognition is in use, the audio unit or the audio-navigation unit sends the fan mute signal to the climate control unit via the B-CAN. The voltage operating the blower fan may be reduced depending on the current fan speed.

Voice Tag Function

The audio unit or the audio-navigation unit can save the voice tag to the memory for making a call by the voice recognition. The voice tag saved at the audio unit or the audio-navigation unit is related with the Speed Dial.

Short Message Service (Display Audio Type)

The audio unit or the audio-navigation unit processes the short message service (SMS) data sent from the cell phone. The text message information is displayed on the display.
