System Operation

Below is a guide to the functions available via the head unit buttons using the latest Arduino sketch version 3.6:

Basic functions:

  • Press NAV - Switch to Android mode
  • Press NAV when already in Android mode - launch preferred Navigation App
  • Hold NAV for 2 seconds - Switch to original Jaguar Navigation
  • Press AUDIO/TEL/CLIMATE/MENU - Switch to Jag mode
  • Hold MENU for 2 seconds - Turn off LCD screen (any button will switch it back on)
  • Double Press FRONT HEAT - switch to AV1 input (Front Camera)
  • Double Press REAR HEAT - switch to AV2 input (Reverse Camera)
  • Press 'Skip Backwards' (down) steering wheel control button - skip to previous track in media player (CD must be playing)
  • Press 'Skip Forwards' (up) steering wheel control button - skip to next track in media player (CD must be playing)

Advanced functions:

  • Hold REAR HEAT and press RIGHT TEMP UP/DOWN - Adjusts the Odroid shutdown delay, you will hear one click for every 10 minutes up to a maximum of 60 minutes. Useful when leaving the Android system running updates, syncing music files etc etc. After shutdown, the delay returns back to the default 10 minutes for next time
  • Hold RECIRC for 10 seconds - Cycle the power to the Odroid to force a hard reboot, for example if Android or an App crashes

Super Advanced functions - configuration mode:

(Ensure ignition key is in I position before following the below, and you only need to select the functions you wish to change as other settings remain stored):

  • Hold AUTO (A/C on the X-type) for 10 seconds - enter config/calibration mode (you will hear the relays click 5 times to confirm) then:
    • Press AUDIO to perform steering wheel control calibration - you will hear the relays click 5 times to confirm, then within 10 seconds:
      • press TRACK UP briefly (you will heard 5 clicks to confirm)
      • press TRACK DOWN briefly (you will heard 5 more clicks to confirm)
      • 5 further clicks indicate calibration data now stored.
      • If no button is pressed or there is an error, calibration will be cleared and steering controls disabled (you will hear 8 fast clicks in this case)
    • Press FAN UP to toggle enable/disable Media player auto-play - (1 relay click = disabled, 2 relay clicks = enabled)
    • Press FAN DOWN to toggle enable/disable Media player auto-stop - (1 relay click = disabled, 2 relay clicks = enabled)
    • Press RECIRC to toggle enable/disable force steering wheel controls always active - (1 relay click = disabled, 2 relay clicks = enabled)
    • Press MENU to reset the Arduino microcontroller (only use if having problems)
    • Press AUTO (A/C on the X-type) to exit config/calibration mode - (you will hear 5 clicks to confirm)

Extra tips:

  • Setting preferred Navigation App - To reassign the function of the NAV button when already in Android mode, launch the Odroid Utility app, scroll down and change the application associated with the F10 key to the Navigation application of your choice (or in fact any application).
  • To enable correct shutdown - ensure that the Terminal Emulator application is associated with the F7 key within Odroid Utility
