Knob operation:

Commander switch (multimedia control module)	Knob	Description
Courtesy of CHRYSLER GROUP, LLC	Tilt (forward/back, left/right)	Moves the selection area on the radio display screen. The selection area can be tilted in the lateral direction for left/right, and the longitudinal direction for forward/back.
	Rotation	Moves the selection area on the radio display screen. The selection area moves according to the rotation direction.
	Pressing down of the commander knob	Switches to the selected menu screen. Launches the selected menu.

There are three function buttons in front of the commander switch and one button on the left and right sides, for a total of five buttons of appropriate size, laid out in a circular configuration. This arrangement enables a comfortable and stable grip with five fingers of one hand, and each button can be easily pushed with a steady pressure.

The button at the center of the three buttons located above the rotary switch is the "Home" button. This button raised slightly above the others so that it can be distinguished by touch from the "Audio" button on the left and "Navigation" button on the right. Also, the "Back" button and "Favorites" button to the left and right of the rotary switch are designed to match the positions of the thumb and little finger.

Depending on the results of the research, the number of buttons also conforms with the ideal number (5-9) which, being an easy number of items to remember, contributes to shorter operating times.

Settings	The various settings (display, sound, and others) can be changed.

The LVDS Standard*1 

LVDS indicates the electrical characteristics of the signal. LVDS transmits information as the difference between the voltages on a pair of wires.

It has a high speed digital interface (Data rate from hundreds to a few thousand Mbit/s) featuring low voltage, low power consumption, and noise reduction.

The communication between the ETM and the radio display uses the High-bandwidth Digital Content Protection (HDCP) protocol. The HDCP system or protocol is an anti-piracy protection protocol that prevents unauthorized reproduction of the content.

Internet Radio 

Aha™ Radio is an application that can be accessed easily by personalizing various internet content such as internet radio and podcasts. "Feeds from friends" can be checked in conjunction with Facebook or Twitter. Local restaurant and coffee shops can be searched using the Location Based Service, and by obtaining traffic information in real time, the user's travel is supported. The service content provided by Aha™ differs depending on the country in which the user resides. The service content provided by Aha™ Radio varies depending on the country in which the user resides. For detailed information regarding Aha™ radio, go to http://www.aharadio.com/  .

Stitcher™ radio is an application that streams internet radio and podcasts on demand.

LVDS signal conversion	Converts signals sent from the units related to the entertainment system to a LVDS signal and displays each type of information in the radio display.
Audio transmission signal	Transmits the audio signal received from Bluetooth® enabled devices and USB devices to the RRN. The ETM receives audio signals from the voice recognition microphone and executes the commands.
Fuel economy monitor	Receive the calculated average fuel consumption information from the instrument panel via CAN. The average fuel consumption of the current drive cycle is calculated by the ETM based on the fuel injection amount and travel distance signal sent from the PCM. This information is displayed as fuel economy monitor in the radio display.
Navigation	Perform map display and route guidance based on the map data received from the GPS signal and the SD card slot hub. The turn-by-turn function displays the travel direction of the route guidance in the active driving display. The turn-by-turn operates when all of the following conditions have been met: Route guidance of navigation function is operating. Navigation is set to ON using the active driving display personalization feature.

The ETM uses the integrated Bluetooth® driver and aerial to establish communication between Bluetooth® enabled mobile devices, such as a smartphones. The communication range of a Bluetooth® equipped device is about 10 meters (32 feet). To establish Bluetooth® communication, it is necessary to pair the Bluetooth® enabled mobile device with the ETM.

A maximum of seven devices including hands free mobile phones and Bluetooth® audio devices can be programmed to one vehicle. It is possible to use 1 function for each Bluetooth® enabled device.

The profile indicates the wireless communication standard. Wireless communication is not possible if the profile of the Bluetooth® enabled devices differ from that of the ETM. In addition, depending on the profile version corresponding functions differ.

• Advance Audio Distribution Profile 1.0/1.2 (A2DP): A2DP is a profile for transmitting high quality audio data through Bluetooth® devices and wireless transmission technologies.

• Audio/Video Remote Control Profile Ver. 1.0/1.3/1.4 (AVRCP): AVRCP is a profile that provides a standard interface to control television and audio devices. The function differs depending on the version.
