I have formatted the usb drive as a FAT32, and when I ripped the songs they were ripped as a MP3, however they are not being recognized by my USB port in my car as being there at all. I'm ripping music off a commercially produced CD to my computer. They are ripping without an issue. I copy them to a USB flash drive, and then putting the flash drive in the car. The car recognizes all my other music that I have, but not the ripped music, in fact it doesn't even appear. I'm using Windows Media Player Version 12 on Windows 7 computer. I put in my USB drive in my computer and then synced it on Windows Media Player with the music that I wanted and it still didn't work. I put it in an old pc running XP, and they ripped and went on the USB and the car recognized it just fine. But for some reason it is not on the Windows 7 version. I've checked the properties on the file, and the settings of the rip procedure on both the Windows 7 and XP machines, and I can't see a difference. I even changed some properties in the ripped file, turning off archive, and still nothing. Any help that can be provided is appreciated.
