The Infotainment Control Buttons

commander-knob
The HMI (Human-Machine Interface) Multimedia Commander panel is designed to be operated entirely by feel (once you get used to it), to control all of the functions of the infotainment and connectivity system and the intuitive “joystick” knob can be moved left/right/forward/back and rotated clockwise/counterclockwise – to navigate through the menus, scroll through lists and zoom in/out on the maps.  Pressing down on the Commander knob will select the current highlighted option.  As for the other 6 dedicated Commander buttons:

Use buttons surrounding the multimedia commander:

  • Entertainment
    – access the audio menu
  • Home
    – return to the main menu screen
  • Navigation
    – access map surrounding current location and navigation menu
    (if navigation is not enabled, a GPS location screen with compass will be displayed)
  • Volume
    – Turn to adjust volume; Nav volume is independent of Entertainment volume and can also be adjusted with the volume knob (while speaking instructions)
    –  Push down to mute Entertainment audio; does not effect Navigation volume
  • Favorites
    – access your stored favorites:
    up to 50 AM & FM radio stations 
    up to 50 contacts from your phone (if paired and downloaded)
    up to 50 navigation points (if navigation is enabled)
    – long-press to store particular items as favorites
  • Back
    – returns to previous screen

Also note that if you ever want to reboot the system without turning off your ignition for a moment, simply push both the Mute + Nav buttons for 10 seconds.

In addition to the Commander panel, there are 7 other buttons that interface with Infotainment system, located on the left side of the steering wheel.

  • A short tap of  Button [1] is the Bluetooth Make Call
  • A short tap of  Button [2] is the Bluetooth End Call
  • Pressing the Talk button [center portion of 3] allows you to input  a voice control command, however by pressing it again, you can skip the voice guidance response and speak the next command
  • Pressing the Volume buttons [upper and lower portions of 3] functions the same as the Commander volume control
  • In Radio mode, a short tap of  the Seek* buttons [upper ⇒ and lower ⇐ portions of 4]  will take you the Next/Previous favorite radio station in the programmed order, whereas long presses of the same buttons will seek to the next/previous playable radio station in the current AM/FM band.  When playing streaming audio, a short tap of these same buttons will serve as Next/Previous/Restart, whereas long presses will serve as Fast Forward/Rewind
  • The eighth button [center portion of 4] doesn’t interface with the Infotainment Center, but instead toggles various functions within the small digital display to the left of the tachometer

The menus that your dealership technicians access to diagnose your Infotainment system or to update the firmware can also be invoked with the Commander buttons, however I suggest all you do is just scroll through seeing what all the options are without actually selecting them (you can brick the system if you mess around with these options).

Diagnostics Menu
Press & Hold: Music + Favorites + Mute until the Diagnostics menu comes up.

You can use the Commander knob to scroll through all the different options, each described below:

CPU/MEM/VIP Performance Monitor
Press & Hold: Music + Back + Mute until the 3-color bar overlay comes up in the right corner of your screen.   You can then operate your Infotainment system and monitor each function’s effect on performance with either that small overlay, or by tapping the overlay, bringing up a semi-transparent full-screen view of the Linux Performance Monitor.

It is temporary function, so the performance monitors will disappear at the next reboot.

If you have any good tidbits to add to this, leave a comment.  I’m hoping that there might be some other unknown functions and “Easter Eggs” for these buttons using long presses, etc.   I stumbled on the radio station scan function quite by accident 😉
