Doesn't answer your question but here is an alternative a USB Flash Drive. I copied vinyl reocords and CDs to a USB Flash Drive with over a 500 songs library to plug in to the USB port.I agree I bought one that plugs in or tunes to a radio station nothing is working plus the car doesn't have an AX plug either. So frustrating I probably would have bought something eles. This is the 1 thing I hate about my 2019 blazer permire!!!! Awesome system that I really don't use that much!!!
