My 2024 2500 Sierra goggle maps has frozen on me a couple of times. It loses connection to the GPS and just quits updating my location. I eventually figured out that when that happens, you must go into settings and clear the cache memory on goggle maps. I believe it has a memory leak. The other complaint about google maps is that it frequently does not send directions to my HUD. Stopping and restarting the truck seems to help that sometimes.
I downloaded waze app to the truck. Waze on the truck takes forever to load. I have basically gone back to using my phone gps for long trips.
I am a geek. I work in large and complex software systems maintenance and governance. The software on the truck has multiple bugs relative to integration to the user interfaces and each other. I am not convinced that the processor or hardware supporting the software is sized correctly because it seems to wait for processor time.
