id1600000003a1
Purpose
• Controls the audio signal from the entertainment system-related parts.
Function
Tuner switching function
-
• The remote tuner (RT) switches the tuner mode built-into the remote tuner (RT) based on the control signal sent from the connectivity master unit (CMU).
Audio signal output function
-
• The remote tuner (RT) outputs the audio signal sent from the following units to the speakers.
-
― CMU― USB port/SD card slot hub
-
RS485*1 signal conversion function
-
Note
-
• The RS485 *1 signal wiring harness is used in the following cases:
-
HD radio ™
-
― Radio broadcast logo, album art, or song name is sent to CMU from remote tuner (RT)
-
-
• The remote tuner (RT) creates data from the radio waves received from the glass antenna and converts the created data to a RS485 *1 signal and sends it to the CMU.
*1 :RS485 corresponds to a linear, multi-drop configuration with bi-directional transmission, which is one of the possible types of serial communication, having a maximum transmission speed of 10 Mbps.
ALC (auto level control) function (Without Bose®)
-
• When the remote tuner (RT) receives the vehicle speed signal sent from the instrument cluster, it automatically changes the volume and audio quality according to the vehicle speed and compensates for the passengers’ sense of a lack of audio volume which occurs as a result of external noise while driving.
FM phase diversity function
-
• Reception sensitivity improvement and noise reduction have been achieved by receiving FM radio signals from multiple antenna amplifiers, and synthesizing the received FM radio signals.
