Smartphone Linkage Function

This function helps to ensure the safe use of a smartphone while driving. Connect a smartphone to the audio unit to use it. Connection methods vary depending on carriers.

When using the navigation function via a smartphone, the audio unit can display the navigation map screen that is in the connected smartphone. In this case, the GNSS signal is received by the audio unit, and the vehicle signals are received from the YB-CAN A bus as information to improving the accuracy of vehicle position.

When using the voice recognition function via a smartphone, the HFL microphone in the roof module picks up the driver's voice, and sends the voice signal to the smartphone via the audio unit using a USB, Bluetooth®, or Wi-Fi connection.

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