Mercedes 2010 S-Class

Hi and thanks in advance for the help, i am looking for a point in the right direction i have an S-Class 350 Merc and am trying to update the comand, sat nav and bluetooth as all are outdated and causing their own issues. I downloaded NTG4 2011-2012 and burned it onto a 4.7gb Maxell disc on speed 4 via imgburn and when i put it into the car disc drive it said unreadable disc
Two problems
1. the download didnt say it was compatible with the S-Class so i dont know whether it is
2. if not can someone direct me to the download

I would be greatly apprecitive
