Correction

A new radio software update, 22.8, 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 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.

event without reading Determining Where to Start –
Checking for Update Status first to avoid programming
failures or module lockup conditions.
Important: 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.

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

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
