ISO 9660 and Joliet are for data discs. Not all car audio players of
that era can read them. Unless you're sure that "old 2002 car cd player"
supports MP3 discs, you're better off with CD-DA (audio CD).

Thank you as I just want to know what settings to use to burn about 30 MP3
songs so that they play in any old cd player.

Bad for me that "CD-DA" isn't one of the options.
It must be called something else.

I ruined a ISO9660 + Juliet coaster already as it did not play in the car
cd player. I only have 4 CD-R 700 MB blanks left so I'm trying not to make
them a complete set of coasters.

Here's what I am doing.
1) I put a blank cd (650MB) into the computer drive
2) I bring up ImgBurn which finds my computer's DVD +/- RW drive
3) At "What would you like to do?" I use "Write files/folders to disc"
4) I put the 30 MP3 files into the ImgBurn "Source" window
Now I have to make the choice.

In "Options" are only these choices (default listed first).
Data Type: MODE1/2048 or MODE2/FORM1/2532
File System: ISO9660+Joliet or ISO9660 or ISO9660+Joliet+UDF or ISO9660+UDF
or UDF

Which is the option for "CD-DA"?
