Thanks to Mistoffelees for taking the time to respond. The car is 1991 vintage - pretty much before the Internet bubble. It has the original Blaupunkt CD but no manual. I'm going to check the CD company website for info. If it doesn't read .MP3 files, are there are other downloadable formats for music files or is it all MP3?
The first (which will only be compatible with cd players capable of reading mp3's) is to burn a data cd. This means effectively the cd is like a chunk of harddrive with the mp3 compatable player reading and decoding your mp3 data files as your pc does. You can fit about 80-90 songs on a cd this way.
The second way is to create a audio cd. This will convert the mp3's into *.cda files which are those found on everyday shop bought cds. This means the cd player is only decoding the tracks as it would a normal cd. You can fit 15-20 songs this way.
I suspect due to the age of your cd player and the lack of any mp3 compatible logo on its fascia that the 2nd option is your only choice. This can be easily achieved by burning the cd with a program such as Nero or even Windows Media Player.
Also due to the potential old age of the cd player that you use, i'd suggest using only CDR not CDRW discs. This is as many older players have difficulty reading CDRW discs due to the way they're written and the low reflectivity of the disc surface.
Use a good brand such as TDK CDR's and you should be laughing. (higher quality discs = more reflective = easier for older players to read)
