You'll have to perform a simple test. Does that CD play in other CD-Audio players?
If it does, then your car CD-Audio player may not like CD-R media. I know most (in fact all!) car units won't play CDRW that I've tried.
This is mentioned in the CDR FAQ at http://www.cdrfaq.org/faq04.html#S4-23
When I burn cds in Realone player they will not play in my car. What software will burn cds for me and create cds that will play in my car?
