Condition

Certain 2021 model year Cadillac XT4, Chevrolet Corvette, Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles may not be able to access Apps. A most notable improvement list this software update may correct is located at the end of this bulletin for conditions or concerns a customer may experience.

Correction

Dealers will reprogram the radio.

 

Diagnostic Aids:

If any symptom persists after completing the radio calibration update, it is possible that the customer still needs to accept Terms and Conditions (T&Cs), and/or that their password for OnStar may have expired.

  1. 1. Verification of the calibration being installed can be confirmed by:
    1. a. logging into the Guest Profile and successfully installing an app in the radio.
    2. b. confirm that the OnStar accounts tab now shows accurate data.
  2. 2. Contact OnStar to confirm connectivity with the vehicle and that OnStar T&Cs have been accepted by the customer.
  3. 3. Inquire with the customer to ensure their OnStar, Owner Center, or myBrand password has not expired. If the customer can log into their my.chevrolet.com or my.gmc.com account, this confirms their password is not expired.
