Bulletin No.: 19-NA-279
A new radio software update, version V807, is being released for vehicles equipped with
Infotainment system RPO IOS, IOT or IOU, in addition to providing general robustness
and stability enhancements. This update includes all enhancements from previous
software version releases.
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.
Caution: Be sure to keep the vehicle doors closed
prior to beginning, and during, the USB programming
event.
Tip: Tripping the door latch to closed status with the
door open will allow exit of the vehicle during the
programming process. Do NOT open the latch until
programming is complete.
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 (see “No Updates Available”
image in next section), go to the “About” screen and
verify the build number (i.e., L206, V507, V509, V803
etc.). If the build number is less than V807, proceed
with the software update following the Update
Procedure Using TIS2WEB (USB Download) section
of this document.

Caution: If Vehicle Update screen shows
“Infotainment System Update” (such as the screen
above) do not use TIS2WEB or insert a USB stick. Use
of the USB stick when the Remote Update has already
been downloaded, installed, or paused during
installation could result in program failures or module
lockup condition. The update should be completed
using the Remote Vehicle Update procedure, following
prompts on the infotainment screen. Refer to Update
Procedure Using Remote Vehicle Update after reading
the remaining information in this section if the Remote
Update has already been downloaded to the radio.
• If the remote vehicle update CANNOT be
completed, the radio must be updated through
SPS via USB. Refer to Update Procedure Using

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, radio, etc.

Troubleshooting
Important: When downloading USB update files, be
sure the computer is connected to the internet through
a network cable (hardwired). DO NOT DOWNLOAD the
files wirelessly.
Important: If having issues with the USB drives, try
using a different brand. The USB drive should be

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
