Some owners have reported an issue with their GM infotainment system wherein their favorite selections will be grayed out and inaccessible. Now, a new software update has been released that addresses the issue for Buick, Cadillac, and GMC customers.
As for the issue itself, affected customers will find their favorites grayed out on the infotainment screen, and will receive an error message that says the selection is currently unavailable when attempting to select it. The favorite can be re-saved, which will make the functionality work again briefly. However, the favorite but may again become grayed out and un-selectable later.
Users may have experienced this issue following the GM infotainment 22.8 radio software update. This update may have been performed either from the dealer, or via an over-the-air update.
Earlier this year, GM advised dealers and customers that it was aware of the issue and was working towards a workable solution. That solution is now available though the latest GM infotainment radio software update S22.9. The software update is offered via technical service bulletin (TSB) 19-NA-249.
Note that while the GM infotainment S22.9 software update will prevent favorites from greying out as before, the fix will require the user to identify the currently grayed-out favorites, manually tune to the desired station or stations, and press and hold Favorite to re-save the selection. This process must be followed after the completion of the S22.9 software update.
Affected customers include those with vehicles equipped with infotainment systems that fall under the RPO codes IOS, IOT, or IOU. This could potentially impact the following vehicles:
- 2018-2020 Buick Regal
- 2018-2019 Cadillac ATS
- 2018-2019 Cadillac CTS
- 2018-2019 Cadillac XTS
- 2018 GMC Terrain
