I have a 2021 2LT Blazer. I have used USB devices for my music, since I don't have a smart phone (apple/Android device). I am locked out from browsing the USB while driving. I can only browse the USB(s) when at a complete stop or in Park. GM has said the USB browsing has been disabled as a safety feature. Here is the kicker, I can browse the contacts on my cell phone connected via bluetooth, while driving. Browsing contacts is as great of a distraction as it would be to browse a usb for music to play.
Does anyone have a way around the issue of not being able to scroll through my many artists/albums on my USB drives? I don't even have USB ports in the center console or on-board navigation. I wish I could upgrade and add the navigation component without having to have Onstar.
