Q: BURN A CD IN ISO9660 LEVEL 1 OR 2 FORMAT, JULIET OR ROMEO

HELLO, I HAVE AN IMAC AND AM TRYING TO BURN FILES TO UPDATE GRACENOTE IN MY VEHICLE.  THE SYSTEM IS NOT READING MY CD THAT WAS BURNED AND TROUBLESHOOTING STATES:  "THE SYSTEM MAY NOT BE ABLE TO READ YOUR CD OR USB.  THE CD YOU BURN MUST BE IN ONE OF THE FOLLOWING FORMATS IN MODE1:  ISO9660 level 1/level2, Joliet, or Romeo."  Anyone have any idea how I can burn a cd on my mac to any one of these formats?  Thanks!
