Hi, I have a 2019 1500, LT, AllStar w the non-Bose 8" touchscreen.
I keep all my music for my home stereo on a thumb drive in lossless files (.aif or .flac). These aren't working on the truck. I called Chevy and a lady who I don't know if she understood the question put me on hold for 10 minutes then said the file types supported are .mp3 and .aac.
On one Chevy forum was a copy of an owners manual that said that flac, ogg, mp3, aac, 3gp files are supported.
I'd like to keep a lossless file format (flac), can any of you confirm which audio file formats work on the USB thumb drive?
