'07 v6 Premium not playing MP3s from flash drive
I tried to post this earlier, but I don't see it. Apologies for the duplicate. Anyway, I have a Shaker 500. I followed the procedure in the owner's manual for playing MP3s on a flash drive through the USB port in the console. The display says LINE IN, but nothing happens. I've monkeyed with the volume in case it's on but playing at a low volume. No luck. Any thoughts? I have another audio question but will post that if nobody has a solution for this one.
Thanks in advance.
