Well, good news on this front. After many months of trial and error trying to get my songs on a flash drive to work with the media system in my truck I finally was successful. From what I learned you have to use iTunes (not windows media player) to make this work. I imported the CD’s I wanted to use (fifteen to be exact) into the iTunes library, then I copied the list and pasted them onto the flash drive. and it worked just fine. The system recognized the flash drive and the songs started playing and so far it’s still working okay. I’m not sure (I’m not a super tech guy) but it appears that when you do this iTunes changes the file extension to “Audio” (AAC audio) file that is compatible with vehicle systems.
Bottom line here is that no one from GM or my dealer mentioned that you have to use iTunes with this system. I discovered this because I have a very old iPad mini player I use with my sound system on my motorcycle and figured I’d try it on the truck system. To my surprise it worked. That led me to try what I mentioned above. All those so called Tech folks at GM and the dealer service folks should know this in order to provide good customer service. Maybe I’m being to critical, but if you sell a product you should know how it works. Just my two cents!!!!
If anyone is having the same problem with there media system on their GM vehicle, I would recommend you try this method. FYI, my truck is a 2024 GMC Sierra Denali. I hope this helps anyone else who is having the same issue.
