I had something similar happen, but only the Radio audio did not work similar to the posters earlier in this thread. I had not seen the info about switching to "Safe Mode", but through process of elimination did find "Safe Mode" and enabled it and the Radio audio returned so I knew I did not have a Radio hardware problem. Then switched out of "Safe Mode" and everything has been fine since.
The other thing to keep in the back of your head is the how to "Reset/Reboot" the Infotainment system. Vehicle has to be running and in Park, press and hold the End Call Button on the steering wheel for 10 seconds or until the Infotainment display goes blank, this will force a "Reset/Reboot" of the system.
Sorely disappointed in the processor power in the 2024 and earlier Infotainment system performance. Seems to have enough "Hard Drive" capacity, but between the processor and RAM it comes up short and is WAY too slow. Takes 45 seconds for Waze to load and open on my system with Waze installed on the Infotainment system. I have been through the system and cleared the Cache for each individual App and this did not seem to do much. Even when I do not launch Waze, Maps seems to often take an eternity to launch.
Some people blame the Android OS, but its not Android, I have been running Android devices for 10 years on various platforms and never had anything as slow as this Infotainment system. The real issue is the Infotainment system in the 2024 vehicle is the end of the road for the hardware platform that probably started development back around 2017 or 2018 in order to get the hardware and software ready to launch by 2021. This is true of almost any integrate platform in a vehicle, so often the hardware or at least the processor is almost obsolete before the first system is delivered. Would be great if someone could find a drop in processor that could be updated even if it was soldered to the main board to increase the speed and response on these systems.
While we may see an Android OS update or 2 over the next few years, I doubt this will sort all the bugs. I also do not see a lot of Application updates or bug fixes from GM coming our way either, they have moved on to the newer generation systems and are fighting with them. The worst case situation is if GM outsourced the support for the 2021-2024 systems and did not have long term support contracts in place and/or the development team fragments over time, then we all stuck with buggy systems. Most of this new tech stuff has about 3 year support lifespan these days!
The 2025's are SO much faster and have more features like YouTube and other App available and the system is snappy but I hate the big screen in the 2025's this is specifically why I purchased a 2024. But I doubt we will ever see anything like the 2025 system performance in our systems due to hardware limitations.
