I took a 2010 TL SH-AWD w/Navi for a test drive and I was checking it over for all it's features and couldn't find where they put the Navi disc for this years model. Did they go to a hard drive or flash drive system?

If it's still a disc, can make a backup copy using Nero or something?

 

harddrive based.

also, its illegal to make a copy. 2) People have attempted to copy the dvd, but have never succeeded. 3) the fourth gen DVD would not work with your 3rd gen.
