Anyone Successfully Copied the Mercedes Navtech Navigation DVD's?

Hi

I am trying to make a backup copy of my mercedes ML Navigation dvd. I have a booktype capable lite-on. DVD Decrypter and Nero.

Thanks
David

In the past I have successfully made backups of the older Mercedes navigation CDs for use with the COMAND unit. I used Alcohol 120% on a co-worker’s PC. They used - at least the older CD ones did, anyway - SafeDisc 2/3 as the protection scheme. I don’t know what modern-day ML’s use on the navigation DVD’s, however. I hope you have some way of finding out what they use.
