WHAT!!?????
mp3 data nahi to or kya hai? if the cd player supports mp3 then u can burn a cd via the data cd burn option in nero or make mp3 cd option in the same program and it will be same. i dont know what farhan mean by what he said but i have burned all my mp3 cds as data cd and they work.
about ur problem. most of these van walas have cassette players so its a good idea if you have an mp3 player with cassette adopter. why dont u call him and ask about what kind of system he has.
