Condition
Rear Seat Infotainment Will Not Play on Front Screen in Park After Radio Software Update
Cause

This may be caused by a software anomaly in radio software version
V807.

Correction:
Engineering is working on a new software version to solve this issue. As a
temporary workaround, an older software version is still available until the next
one can be released. Customer review and acceptance is required before
installing older software.
Service Procedure
IMPORTANT: This condition does NOT involve any concern with rear displays. Do
NOT attempt to apply this solution for ANY rear display issue.
Note: Dealers must review the issues that customers may experience if choosing
to revert to an older software version. Some conditions may occur frequently and
could cause undesired operation and a poor user experience.
1. Review with the customer what fixes and improvements (listed below) were

provided in V807 and allow the customer to make the decision to either:
Accept that engineering will release a fix in the future for this front display
playback issue and remain on the current radio version (highly
Recommended); or
Accept those issues that may be caused by using an older software version
and have an older software version installed. Customers must understand
that any of the conditions below can occur repeatedly and may cause
undesired operation of their related system(s).
Customers may experience any combination of the following conditions if they
choose to stay on an older software version that allows RSI system playback
on the front display while in Park. Updates were made in the following areas:
HVAC, Bluetooth, and general system improvements. Most notable
improvements included:
Previously paired Bluetooth device does not auto-connect.

SD Card Error code 0x40000
SD Card Removed message when card has not been removed
Last vehicle position is incorrect until vehicle begins moving
Climate Off displayed on Climate app/page, fan speed greyed out,
temperature selected does not match user setting
Vehicle position may not update on maps or while in a tunnel (China)
Correct translation of Teen Driver Mode to My Driving Coach (Korea)
Unable to use specific point-of-interest (POI) voice recognition
commands (Korea)
Blank or static/scrambled screen
If the customer chooses to remain on V807 until the next update, then no
further action is necessary. A bulletin will be released once new software is
available.
If the customer understands and accepts the possibility that they may
experience any combination of the above listed items and still wants to have
front display playback in lieu of the above improvements, proceed to step 2.
Note: With exception to the special process below, a normal Techline Connect
(TLC) or TIS2Web USB dealer reprogramming event, or an over-the-air (OTA)
radio update will still allow the V807 or later software version to be installed. You
must follow step 2 below to get the older software version. This PI will be
deleted, and this special process canceled once a new radio software version
becomes available.
2. Reprogram the A11 radio following instructions that TCSC will provide.

Contact the Techline Customer Support Center (TCSC) at 1-800-828-6860
(English) or 1-800-503-3222 (French) for a VCI number and programming
instructions.
Caution: Before downloading the update files, be sure the computer is connected
to the internet through a network cable (hardwired). DO NOT DOWNLOAD or
install the files wirelessly. If there is an interruption during programming,
programming failure or control module damage may occur.
Important: Carefully read and follow the instructions below.
• Ensure the programming tool is equipped with the latest software and is
securely connected to the data link connector. If there is an interruption during
programming, programming failure or control module damage may occur.
• Stable battery voltage is critical during programming. Any fluctuation,
spiking, over voltage or loss of voltage will interrupt programming. Install a GM
Authorized Programming Support Tool to maintain system voltage. Refer to
www.gmdesolutions.com for further information. If not available, connect a fully
charged 12 V jumper or booster pack disconnected from the AC voltage supply.
DO NOT connect a battery charger.
• Turn OFF or disable systems that may put a load on the vehicles battery such
as; interior lights, exterior lights (including daytime running lights), HVAC, etc.
• Clear DTCs after programming is complete. Clearing powertrain DTCs will set
the Inspection/Maintenance (I/M) system status indicators to NO.

Important: If the Same Calibration/Software Warning is noted on the SPS screen,
select OK and follow screen instructions. After a successful programming event,
the WCC is located in the Service Programming System dialogue box of the SPS
Summary screen. No further action is required. Refer to the Warranty section of
the bulletin.

Important: To avoid warranty transaction rejections, you MUST record the
warranty claim code provided on the SPS Warranty Claim Code (WCC) screen on
the job card. Refer to callout 1 above for the location of the WCC on the SPS
screen
