It was discontinued last year, MY2023, afaik.
I had some thoughts about different ways of getting the best possible input source into the car audio system, somehow, after I realized the SXM, AM, FM, Bluetooth, USB primary source options input limitations.
So, after realizing the folly of my quest...
I chose to rip my CDs to my laptop, copy them to a few "newest tech available" USB drives, and stopped
at that point.
They sound fine to me, considering the output system they're being played through, and that they're being played in a car like the C8 Corvette, competing with an often very noisy engine behind my head, I realized that was probably about the best I could hope for.
As an exit segue, I'll just say good luck with it. I know you're determined to make it work.
