  • Operating signal is transmitted to AV control unit with steering switch signal when it is operated by steering switch.
  • Refer to System Description for explanation of voice recognition function and touch panel function.
 
 Screen display

  • Switching of display is performed with serial communication between display unit and AV control unit.
  • The image signal to display operating condition is performed with RGB signal, RGB area signal and RGB image synchronizing signal.
 
 AM/FM Radio Mode

  • AM/FM radio tuner is built into AV control unit.
  • Audio signal is received by glass antenna, next it is amplified by antenna amp., and finally it is input to AV control unit. Audio signal is input to audio amp. and audio amp. outputs to each speakers for AV control unit.
 
 Satellite Radio Mode

  • Satellite radio tuner is built into AV control unit.
  • Audio signal (satellite radio) is received by satellite antenna, and it is input to AV control unit. AV control unit outputs audio signal to audio amp. The signal is also outputted from audio amp. to each speaker.
 
 CD Mode

  • CD function is built into AV control unit.
  • AV control unit outputs audio signal to audio amp. and audio amp. outputs to each speaker when CD is inserted to AV control unit.
 
 Music Box Mode

  • Music CD data is stored on HDD (hard disk drive) that is built into AV control unit, and it can be played.
  • AV control unit outputs music (audio signal) that is stored on HDD to audio amp., and audio amp. outputs to each speaker.
 
 CF Mode

  • AV control unit has built in CF replay function.
  • Music (audio signal) that is stored in CF outputs to audio amp., and audio amp. outputs to each speaker when CF is inserted into AV control unit.
