INTRODUCTION

The following information announces reprogramming file availability and provides a software update installation procedure to optimize the new Gen 4 Denso CP1 Audio and Navigation head units utilized in the models listed above. As in previous models, the procedure will involve either downloading the software update files from Subarunet or using those sent directly from Nuspire to the SDS Notebook and transferring them onto a USB flash drive for head unit installation.

It is VERY IMPORTANT  to read and understand this information completely before proceeding.

Service Bulletin is intended for use by trained technicians ONLY. It informs technicians of conditions, which may occur in some vehicles or provides information, which could assist with proper servicing of the vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do the job correctly and safely.

A time line chart along with a complete list of all the conditions addressed and enhancements included in this and previous Denso software updates are provided in "Appendix D"  and "Appendix E"  located at the end of this bulletin.

IMPORTANT NOTE:  The update contains 2 folders and 1 file. When performing an update, the USB must contain the matching number of folders and files and all files must be replaced. ALWAYS use the latest files together as a set.

NEVER reuse or combine files from a prior update with a newer version. 

PART INFORMATION

Materials Required: 

An empty, USB 2.0 or 3.0 storage device (flash drive) will be needed to perform the update procedure. The device should be dedicated to storing and transferring these updating files only. It must be a minimum of 8GB  or more in size and contain a NTFS  file format before downloading the update files onto it. Be sure to locate and re-format any existing USB drives used for updating audio units. They must be fully cleared before adding these new update files to them.

IMPORTANT NOTES: 

• NEVER  change the update file names after downloading them.
• NEVER  save any other files on the same flash drive.

There are various types of USB flash drive available from many suppliers. If the head unit does NOT recognize the USB drive during the reprogramming process due to Controller IC type of USB drive or Compatibility with the head unit, please clear the drive and format for FAT32  instead of NTFS  .

"APPENDIX E"

Symptoms Addressed By Update #5 

Category	Symptom
SXM	SXM sound is not played and the audio source cannot be switched following ignition on.
Audio	When the ignition switch is turned on, the audio source that was playing the time before last (instead of the one playing the last time) is started to play.
	No sound output when turning ignition switch ON-OFF-ON quickly.
Display	When the list order for Phone Book is set "Family Name" first and "First Name" second, it displays in the order of "First Name" first.
	The CID screen display becomes distorted during USB audio playback mode causing icons and text to be displayed incorrectly.

Symptoms Addressed By Update #4 

Category	Symptom
Black screen	While welcome animation on CID is displayed and the driver's door is left open, if turning ignition OFF/ON, the CID screen will be black screen.
	After starting the engine, the loading animation remains and the screen does not transition.
Display	Repeated and consecutive operation of voice recognition activation, CarPlay activation, and the HOME button operation may cause the CarPlay screen to be black screen for several seconds.
	After performing operations 1 and 2 below from the CarPlay screen, returning to the CarPlay screen may cause the CarPlay screen to be black screen. Operation 1:  Switching to a pop-up screen such as the air conditioner screen Operation 2:  Interrupt pop-up screen display by volume operation, etc.
	The date of receipt of a received message is displayed as 2000/1/1. This occurs on some models of phones with Android OS 13 or later.
	When resuming USB audio playing on the same USB drive, there is a mismatch between the played tracks and the displayed track names. (Possible root cause: After playing USB audio, edit the folder structure or song order on the USB drive by PC.)
	The radio preset list becomes completely empty.
	When the "All" tab is pressed on the TravelLink Sports screen, a blank screen may appear.
Function	When the clock was set to ""AUTO,"" the date and time could be shifted to a date approximately 20 years in the future due to anomalous values received from GPS or other reasons. In such cases, the date and time could not be corrected manually and had to be reset by disconnecting the battery terminal. As a countermeasure, a setting screen for manually adjusting the clock display in the "AUTO" setting should be added to the Dealership Mode. Dealership Mode->Settings->GNSS Data Setting
	Update on Bluetooth connection security vulnerability.
	Sometimes, the system does not resume playing from the previously played song, but starts playing from the first song on the USB. (Possible root cause: The last audio source that was playing last time was USB audio. The same USB as last time was plugged in and audio playing started automatically.)
	When updating the CCU software from Dealership Mode, a progress bar for the installation may stop in the middle of the update and the update may not be completed.
	Immediately after turning ignition on, it may take about 50 seconds until SXM audio starts to play.
	CarPlay does not activate. (If the cable is disconnected or inserted while using CarPlay or a temporary contact failure occurs, the system is not activated after that.)
	When a Bluetooth or Android Auto connection fails due to an error on the smartphone device, the connection is given up because there is no way to recover from the CCU. The system behavior is changed so that the CCU will attempt to restore the connection state by sending a request to the smartphone device once again.
	When connecting Apple devices loaded with iOS 16.4 or later, the short message feature is not available.
Operation	Touch controls on the CID screen do not work.
	When a preset channel on the SXM is pressed, a different channel is selected instead of the registered channel.
	Touch operation of the CID screen does not work. The screen is displayed and sound is played, but only the operations are not available.
	When the engine is started with the iPhone connected via USB, CarPlay may not start even if the CarPlay icon on the home screen is pressed. (This can be resolved by reinserting the USB cable.)
	Continuous operation of Preset Up/Down on SXM preset channels causes switching to channel 0.
	Voice recognition does not recognize certain SXM channel names.
	When getting CCU USB logs from the Dealership Mode->Diagnostics Recorder screen, it was necessary to turn off ""Begin Recording"" before performing ""Export Data to USB"" then turn ""Begin Recording"" ON again after log acquisition was complete. The sequence of operation is improved by automatically turn ""Begin Recording"" to ON after the logging is complete.
	After indicating "Play Artist ******" via voice recognition, the user selects a specific song on the displayed list to start USB audio playback. Then, instead of the song on the list, the specific song from the first album of that artist will be played.
	When starting hands-free call using voice recognition commands, a warning message "Please wait a minute" may appear on the meter display and the call cannot be initiated.
	When using CarPlay, it may suddenly disconnect and not reconnect even after unplugging and plugging the USB cable.
	CarPlay will not be activated.
	Operation of the CID screen and reaction may become slow while using Bluetooth audio.
	After USB audio playing is completed to the last song with the repeat function off, pressing search to switch the playing mode (folder, artist, album, etc.) and then selecting a song will prevent playing from starting.
	After canceling the phonebook transfer that appears automatically when connecting via Bluetooth, attempting to transfer a phonebook by manual operation may fail to initiate the transfer.
	If there is no response from the iPhone/Android device for an extended period, a pop-up will be displayed, indicating that the screen cannot be shown due to a communication issue with the device.
Reset	While playing Bluetooth audio, CID screen may turn into a black picture and does not resume until the ignition switch cycle (*1) is performed. NOTE: (*1): Turn off the ignition switch, open and close the driver's door, wait for about 3 - 5 minutes then turn on the ignition switch again.
	The CID screen may reset within 3 minutes after engine starts.
	The CID screen may reset within 3 minutes after engine starts. No sound is heard from the speaker and ""No Audio Playing"" is displayed on the CID screen.
	When maintenance dates, birthdays, and anniversaries are set on the same day, popups will appear in sequence on the top of the CID after engine starts when their dates are close. At this time, if an operation is performed to delete the maintenance date or birthdays or anniversary date registration within a few seconds immediately before the display, the CID screen will reset. However, the BRZ screen configuration does not allow the delete operation to be performed before the display, so this event does not occur actually.
	When an iPhone/iPod is connected via USB cable and connected as an iPod audio device instead of CarPlay, the CID screen may reset when song information is received. (This occurs when some of the song information data sent by the iPhone/iPod is missing.)
	When the ignition is repeatedly turned ON/OFF in quick succession, CID screen may reset right after startup.
	After turning the ignition ON, the CID screen resets approximately after 6 minutes. This occurs due to a communication issue within the CCU causing the radio tuner to become unresponsive.
	A few minutes after ACC-ON, the CID screen may reboot. This is caused by failure to start software related to button operation during CCU startup.
Voice and Audio	The volume of the+B43+C43:C50+C43:C49+C43:C50+C43:C49+C43:C48+C43:C49+C43:C43:C52
	Audio operation (audio playing, volume change, audio source switch) may not be available after engine starts.
	After pressing the radio icon from the HOME screen, the FM radio may not sound.
	When a hands-free call is started while music is playing in AndroidAuto, and the call is ended after the ignition is turned off/on, music is played from the device itself instead of the vehicle speakers. This may occur when the following steps (1) to  4 are operated. Start a hands-free call while music is playing on the AndroidAuto App. ""See you"" is displayed on the CID screen after turning the ignition off, and then the screen disappears. Turn the ignition on again without waiting for a long time. End the hands-free call.
	Music is not audible on AndroidAuto if the following steps (1) to  3 are performed. (Unplugging and plugging in the USB cable will solve this problem.) Start hands-free call while music is playing on AndroidAuto. Turn off audio by pressing and holding the volume button. Cancel audio OFF and end the call.
	After ACC is turned OFF while SXM is playing, SXM may not play automatically the next time the ACC is turned ON.
	No sound from all audio sources after engine starts, and "No Audio Playing" is displayed on the CID screen.
	When volume is changed when using CarPlay, the speakers may not temporarily sound.
	When calling with CarPlay function, the other party's voice can be heard, but yours may not be able to reach the other party.
	When using the voice recognition feature while playing audio or radio, the speaker may not sound.

15	Even when using the same mobile device that was paired previously, a message of "Are you sure you want to activate this profile?" is prompted and confirmation is needed to activate the device.
16	Cover art of previous music is displayed when playing music without cover art in USB audio. It can occur when music with and without cover art is mixed and stored together a single USB.
17	Command "Play Artist <Artist name>" to play all music of particular artist in USB music mode, only the first item listed for the artist is played.
18	While playing music from USB, the music title displayed on the screen differs from what is being played. It can occur by the following sequence of operation: Display a list of music on the USB audio screen. Change the screen to other screen than the music list. The music play is continued and moved on to a music in a different music list. Change the screen back to the music list in the USB audio screen.
19	In USB music mode, some music is skipped and the music in the next folder is started. Under following condition Play USB music in "Folder" mode with repeat mode setting "Repeat All."

Start to play music by pronouncing <Artist> or <Album> though voice recognition system.
28	DAB preset channel is displayed as not registered due to loading error.

Symptoms Addressed By Update #2 

Number	Symptoms to be Improved:
1	The CID stays black following reboot. Reset doesn't always recover this condition.
2	The CID stays black or very dark even after the ignition switch is turned on due to back light malfunction.
3	When using CarPlay, the screen goes to black and/or CID restarts. It occurs when the CID processor falls under irregularly high load conditions.
4	The CID restarts about 3 minutes after turning on the Ignition Switch. It occurs when the CID processor falls under irregularly high load conditions.
5	System reboot due to application failure. Software robustness has been imporved to prevent CID and CCU from resetting whenever its individual function fails.
6	When the vehicle comes to a place on a highway where there are multiple exits with combinations of alphabets and numbers (see example below) the CID cannot process the information correctly for turn-by-turn navigation and restarts. Example:
7	CID restarts when Navigation system is re-routing the route crossing the border of the states. When the customer veered off navigated route and the re-routed route includes the roads across the boarder of states, the calculation is not properly processed and the CID restarts.
8	CID restarts, while it is connected to Wi-Fi. It occurs when Wi-Fi signal includes illegible data.
9	CID restarts after the ignition switch is turned off and on again before the CID shuts off.
10	No functional response on touch screen in Radio mode even though the touch sound and visual reaction are confirmed.
11	Reprogramming process takes extensive time (40 minutes or more.) After the ignition switch is turned off and on again, the combination meter display mode changes itself and shows the ECO gauge (Current fuel consumption/Driving range on remaining fuel.) Both attribute to processing errors in CCU.
12	When conducting USB reprogramming, the screen transition to error screen instead of confirmation screen.
13	When "Software Update" is selected in the Dealership Mode, the following initialization process does not end more than 20 minutes.* NOTE: *In case this USB update failure occurs, retry updating according to the instructions in "Appendix A"
14	When the FOTA pop-up (new software availability notification) is displayed while the CarPlay is being used, the display comes back to CarPlay screen even if the customer tries to get into the FOTA screen.
15	Call function does not work in the Message List (after ignoring the incoming message notification.). However, the call function can still be used after getting into the Message Content screen by tapping the message list.
16	Message reading function of short mail does not resume and ends once it is interrupted by barge-in voices for other functions.

New Functions and Enhancements included in Update #2 

Number	New Functions and Enhancements:
1	Icons of home screen change to those of the US specifications even though the original specification is not of the US.
2	Two ways of MOTA operations, i.e., by connect CCM to Wi-Fi or by transferring the downloaded map data to CCM via smart phone are executed simultaneously by error.
3	One of the Pop-up Error Messages displayed during the FOTA operation in case of weak Wi-Fi signal is not intuitive. Even if the customer tap "OK," it does not transit to another screen. As the improvement for this inconvenience, the message is changed so that the customer finds the reason why the FOTA operation has been paused. Also a "Resume" button is prepared so that the customer can do the rest of operations after necessary action (moving the vehicle to another place with better Wi-Fi connection**, or tethering the CP1 to a mobile phone, etc.) NOTE: **The FOTA operation can be paused when the Wi-Fi indicator at the upper right corner of the CID is not in "Good" or "Excellent" as shown below.
4	To prevent the overall CID system (CCU) from being reset whenever its individual function fails, the robustness of the software has been improved.
5	CD returns to CD deck too fast to pick it out after ejection button has been pressed. As the countermeasure, the pausing time is extended to ease the operation.
6	Past DTC stored in the CCM cannot be captured by SSM when new current DTC is detected. Both DTC's can be captured by SSM after letting the system into sleep mode and turning the Ignition Switch on again.
7	Music in the different folder in a USB stick can be selected by Track-UP/Down operation.
8	Music in multiple folders in a USB stick can now be played continuously whereas they could not be played unless they were in the root area of the USB stick.
