Long after I ordered one for $18, it suddenly dawned on me that if it

USB-connected flashdrive.

The car radio won't see a USB device, it'll see an aux level analogue
input,

That's what I finally realized.

hopefully the $18 device acts as an MP3 player with e.g. 1/8"
jack analogue output?

I dont' expect that. I think I'll have to use an actual MP3 player,
which isn't so bad now that I'm used to the idea. I had a rental car
which played mp3's on flashdrives

Got a link?
