Bulletin Number: 15-211-17R; Revised 11/13/23

Page 17 of 22

PREVIOUS Version: The head unit power is turned OFF by pressing the Power/Volume knob
for 4 or more seconds. On the next ignition ON, the display remains OFF / black while the audio
begins playing automatically. This was the prior characteristic operation.
NEW Version: The head unit power is turned OFF by pressing the Power/Volume knob for 4 or
more seconds. On the next ignition ON, the display remains OFF / black and the audio will also
be OFF until the Power/Volume knob is pressed to turn the head unit back ON.
NOTE:

•

•

The Mute function of the Power / Volume knob (a brief press and release of the Power /
Volume knob to mute audio output) is unchanged.

•

A “system reboot” function is initiated by pressing and holding the Power / Volume button for
10 seconds. This feature was included as part of the previous (11/2017) software update.

An enhancement of Voice Recognition feature has been made for improved HVAC system
interface and recognition of temperatures requested in Fahrenheit instead of Celsius. EXAMPLE:
“Set temperature to 75.” With the previous version, the system interpreted “75” as degrees
Celsius which would have been 167 degrees Fahrenheit and outside system parameters. As a
result, there was no response from the HVAC system.

Additional Symptoms and Enhancements addressed by previous updates and also included in this
latest (June 2019) update:
1- No streaming audio; when using the Pandora® app, there is no audio output.

2- “Media is loading” is displayed on the screen but, the media never completes loading.

WTN-74R:
1- Radio station presets disappear (touch screen buttons return to “Initializing”).

2- STARLINK “Telematics Service in Progress” screen freezes.

3- Apple Car Play / Android Auto function does not operate (“No Device Connected”).

4- The complete guidance route can be displayed.
5- A Longitude and Latitude search feature has been added.
6- A “Beep” notification feature has been added for driving time and rest periods.
7- This latest (November 2018) update also includes a security enhancement.
For reference, the previously released WTN-74R symptoms are also provided below. The main
purpose of WTN-74R was to address display screen freeze-up during Back-Up Camera display (when
the shifter is in “R”). In addition, the screen may also freeze when either the Subaru STARLINK or
Disclaimer Caution / I Agree screen is displayed.

and the hard key buttons are illuminated (on solid, or flashing / blinking).

2) Time of day displayed in the MFD is incorrect and the arrival time displayed in Navigation unit
is also incorrect.

3) The time in the MFD automatically reverts to a “default” setting, even after setting the time using
“Manual” mode.
4) Audio volume goes to maximum automatically after one click of the volume up button on the
steering wheel. In some cases, this condition may also occur without input from the operator.
