When 2018-2021 GM models equipped with an Infotainment 3 System (RPO IOR, IOS, IOT, IOU, IOV) (Fig. 26) come into the dealership with various system concerns \u2013 the radio display freezing, Bluetooth not connecting automatically, or certain features not accessible \u2013 and programming updates are determined to be needed, is the right repair to update the radio software or the radio calibration? Or both?<\/span><\/p>\n

 <\/p>\n

There may be some misunderstandings about the differences between software and calibrations, which are not the same thing and are not interchangeable terms. Calibrations instruct the radio what to do while the software tells the radio how to do things. <\/span><\/p>\n

For example, when a radio plays the welcome animation at start-up, a calibration instructs the radio which brand name and logo to display. It\u2019s the software that tells the radio how to display those graphics, including how fast or slow to play the animation, the image size, and how long the image is displayed. <\/span><\/p>\n

 <\/p>\n

Calibration Updates<\/b><\/span><\/p>\n

Calibrations for the radio are updated infrequently. In the Service Programming System (SPS), the radio calibrations are updated by selecting Radio \u2013 Programming. (Fig. 27) <\/span><\/p>\n

If the radio is being replaced, the new module will require calibration programming using SPS, followed by USB programming for the software. Be sure to always check the appropriate Service Information and Bulletins for details on related programming as well as the correct programming order for each specific repair. <\/span><\/p>\n

Software Updates<\/b><\/span><\/p>\n

Software updates occur much more frequently in order to address fixes and continuous improvement enhancements, such as issues with Bluetooth, device projection (Android Auto\/Apple CarPlay), Sirius XM, screen displays, and instrument cluster\/Driver Information Center (DIC)\/Head-Up Display (HUD) concerns. Each software update includes all enhancements from previous software version releases.<\/span><\/p>\n

The software releases are usually announced with a Service Bulletin once the programming is available. The software release also may be pushed to vehicles remotely through an Over-the-Air (OTA) update. (Fig. 28) If the remote vehicle update cannot be completed, the radio must be updated through SPS via USB. Keep in mind that not all software releases are distributed as OTA updates.<\/span><\/p>\n

 <\/p>\n

 <\/p>\n

In Techline Connect, the radio software is updated by selecting USB File Transfer. Use a USB 2.0 flash drive with a minimum capacity of 16 GB when updating the software.<\/span><\/p>\n

 <\/p>\n

Before Beginning an Update<\/b><\/span><\/p>\n

Before proceeding with a USB File Transfer to update the software, check for any Infotainment System OTA updates on the infotainment system. Go to Settings > System tab > Updates on the infotainment screen to verify if an update package has been remotely downloaded to the vehicle. <\/span><\/p>\n

If an update is shown on the Updates screen, the software update must be performed using the download that is present on the vehicle.<\/span><\/p>\n

If there is not an update available, the build number must be verified before a software update is performed using the USB File Transfer. (Fig. 29) <\/span><\/p>\n
