Hi, I was just wondering if anyone knows the difference between the version 2.03 Navigation DVD that came with my 2001 CL vs. the 2.05? Is it much of an upgrade? Someone is looking to sell the 2.05 but I don't know if it's worth it. I find it hard to pay $185 for the new ones v2.11b and all I need is a little upgrade. Any help would be appreciated!

Thanks in advance!
