Correction

A new radio software update, version 135116, is being released for vehicles equipped
with Infotainment system RPO IOR, to provide general robustness and stability
enhancements.
This update can occur remotely through in-vehicle prompts from the radio display.
However, some customers may decline the vehicle update or the update may be
unsuccessful. Along with the vehicles mentioned above, vehicles in unconnected
markets, and fleet customers will need the dealer to reprogram the radio with the new
software package.

Service Procedure
Important: If the remote vehicle update has been
downloaded or installed, DO NOT install the update via
USB. DO NOT attempt to complete the programming
event without reading Determining Where to Start –
Checking for Update Status first to avoid programming
failures or module lockup conditions.
The update procedure in this bulletin includes the
following four sections:
• Determining Where to Start - Checking for Update
Status
• Update Procedure Using Remote Vehicle Update
• Update Procedure Using TIS2WEB (USB
Download)
• Troubleshooting
Important: DO NOT attempt to complete the
programming event without reading Determining
Where to Start – Checking for Update Status first to
avoid programming failures or module lockup
conditions.

Determining Where to Start – Checking for
Update Status
The process used for this update is dependent on the
status of the software on the module and if the module
already has a remote install package downloaded. To
verify if an update package is already on the vehicle,
open “Settings” and then scroll to “Updates” on the
radio screen. If an update is shown under the “Updates”
screen, proceed to the Update Procedure Using
Remote Vehicle Update section of this document.
If no update is shown, enter GDS2 to view the A11
Radio Software Module 1 value. If Software Module 1
value is the old software part number, 84639917,
84691626, or 84762987, proceed with the software
update following the Update Procedure Using
TIS2WEB (USB Download) section of this document.
If the part number is 84785838, then the radio is
already updated and no further action should be taken.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
