I went through that very process last winter vacation. I used FreeRIP to convert about 150 CDs to variable bit rate MP3 files and then used Windows Media Player to fill in the album, artist and track information and to sync the files to the USB stick.
Works fine on my non-iDrive radio using the center console USB port. I would suggest doing a single album first and then confirming your particular radio will support your chosen format; many older ones won't support VBR MP3 files if that's what you choose to use.
