Recommendation/Instructions
An updated radio software calibration has been released to address the above conditions. Update the radio using a USB FLASH DRIVE and the Service
Programming System (SPS) with the files available on TIS2WEB. Refer to the SPS procedures in SI.
Important: This procedure is a USB flash drive programming event. This IS NOT a standard TIS2WEB programming event. This procedure requires a USB
2.0 flash drive. The minimum USB flash drive capacity requirement is 4 GB. The software downloaded to the USB flash drive can be used to update all vehicles
involved in this bulletin.
Any existing data on the USB flash drive will be erased during the TIS2WEB-to-USB flash drive download process. To ensure important data IS NOT deleted
from the USB flash drive, transfer the data from the USB flash drive onto another approved data storage device BEFORE attempting to download software
from TIS2WEB.
Once the software is downloaded to the USB, DO NOT add any data to the storage device.
After USB programming has been completed, reprogram the HMI module, even if the HMI module has the latest calibrations, using the Service Programming
System (SPS) with the latest calibrations available on TIS2WEB. Refer to the SPS procedures in SI.
Clear any DTCs.
Important: The vehicle modules MUST go to sleep for 5 minutes after programming the HMI module. If not, the vehicle may not have sound, blank screen, no
touch response or the wrong splash screen may appear on the screen. If this happens, shut off vehicle and wait the required 5 minutes before starting vehicle
again.
Important: For RPO IO5, there was a production change in the software to change the Navigation icon (NAV) display to NAV OnStar icon display.

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.
