Additional Options (RPOs)
Vehicles equipped with Infotainment system RPO IOS, IOU or IOT
Note: The IOR radio does not get V160 and uses a totally different software. DO NOT
attempt to program an IOR radio with the software referenced in this bulletin.
Condition
Some customers may comment on software related issues. Continuous improvement
software updates are being released with improvements made in several areas. V160
contains over 35 improvements. Refer to V160 Most Notable Improvements section
below.
Cause
The cause of the condition may be software anomalies.
Correction
A new radio software update, version V160, was released to service for vehicles
equipped with Infotainment system RPO IOS, IOU or IOT. In addition to providing general
robustness and stability enhancements, this update includes all enhancements from
previous software version releases.
Note: The IOR radio does not get V160 and uses a totally different software. DO NOT
attempt to program an IOR radio with the software referenced in this bulletin.
Important: Some technicians are reporting that the
radio remains on an older software version after the
radio displays the software update completed
successfully. It is important to ensure that the
technician is inspecting the full information found within
Build Number and not other rows of information on the
same screen. This requires the user to locate the Build
Number, and then select the Information icon (circled
lower-case i) to see the full software version file name.
In these radios, the build number may begin with a
letter other than “V” but this is NOT the software version
and is not unique to the software release.
Important: After pressing the information icon, review
the full software version file name. In the middle of this
long file name you see the V160 (or numerically higher/
lower if a different version is installed).
Important: Improvements will vary by model, build
configuration, system, and sales region. Not all
vehicles have all features.

Service Procedure
Important: Service agents must comply with all
International, Federal, State, Provincial, and/or
Local laws applicable to the activities it performs
under this bulletin, including but not limited to
handling, deploying, preparing, classifying,
packaging, marking, labeling, and shipping
dangerous goods. In the event of a conflict between
the procedures set forth in this bulletin and the
laws that apply to your dealership, you must follow
those applicable laws.
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.
• 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
Page 3
voltage. Refer to www.gmdesolutions.com for
further information. If not available, connect a fully
charged 12V jumper or booster pack disconnected
from the AC voltage supply. DO NOT connect a
battery charger.
• Follow the on-screen prompts regarding ignition
power mode, but ensure that anything that drains
excessive power (exterior lights, HVAC blower
motor, etc) is off.
• Please verify that the radio time and date are set
correctly before inserting USB drive into vehicle
for programming, otherwise an error will result.
• Clear DTCs after programming is complete.
Clearing powertrain DTCs will set the Inspection/
Maintenance (I/M) system status indicators to NO.
Important: The service technician always needs to
verify that the VIN displayed in the TLC left side drop
down menu and the top center window match the VIN
plate of the vehicle to be programmed prior to using
Service Programming System 2 (SPS2) for
programming or reprogramming a module.
• For the TLC application, service technicians need
to always ensure that the power mode (ignition) is
“ON” before reading the VIN from the vehicle’s
VIN master module and that they do not select a
VIN that is already in the TLC application memory
from a previous vehicle.
• If the VIN that shows up in the TLC top center
window after correctly reading the VIN from the
vehicle does not match the VIN plate of the
vehicle, manually type in the VIN characters from
the vehicle VIN plate into the TLC top center
window and use these for programming or
reprogramming the subject module with the
correct vehicle VIN and software and/or
calibrations.
• The Engine Control Module (ECM) is the master
module (for VIP vehicles) that TLC reads to
determine the VIN of the vehicle. If the VIN read
from the vehicle by TLC does not match the VIN
plate of the vehicle, the ECM also needs to be
reprogrammed with the correct VIN, software and
calibrations that match the vehicle’s VIN plate.
• The Body Control Module (BCM) is the master
module (for GEM vehicles) that TLC reads to
determine the VIN of the vehicle. If the VIN read
from the vehicle by TLC does not match the VIN
plate of the vehicle, the BCM also needs to be
reprogrammed with the correct VIN, software and
calibrations that match the vehicle’s VIN plate.

No further action is required. Refer to the Warranty
Information section of this bulletin.
1. Inspect the current radio software version.
Navigate to Settings -> About -> Build Number ->
Information “i” to view and verify the software
version.
• If the build number is V160 or greater, this
bulletin does not apply.

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.
