Greetings limewired1.

Don't know how experienced you are at CDs. Most burners give the option of burning as music or data disk. Older players can't handle MP3s, so music burned as a data disk would play on computer but not older CD players. Same thing with CD-R vs CD-RW. Some (especially older) players are a bit picky.

Tks. Probably the problem. I was burning the CD's using Windows so probably data only - Players in cars are new (09) so that should not be the problem. I'll try burning w/ Nero and see if that fixes things. Much obliged
