Hmmmmm..... now that has me wondering on another issue. I thought all the cars came with 2 USB ports. My 2017 Abarth trim version did, and about a year ago something happened such that only one of them can be recognized at the same time. I used to be able to plug a USB drive in each of them, and in selectable audio sources, it would show as both USB1 and USB2 available. Now, if I plug a device into each of them, the first one will show up as available, and the second appears ghosted (greyed) out. It makes no difference which port is loaded with a device first, they both work... just not concurrently. And that, has me completely baffled and I'm yet to figure out why it happened.I think this is the salient point - 1 vs 2 USB ports.
It would seem a bit silly to remove the USB just because you've switched over to a non-USB source.
