*****UPDATE*******
The latest firmware for the MKII/MKIII Navigation system is V22.1. versions above that are for the MKiV.
The cd was easy to burn; here is where I obtained info: BMW Navigation information | The Web Page of Kristopher Linquist
It gives you a full step by step. Just scroll down to MKIII and you'll find it there.
So heres the story:
Heres my old ugly software that I wanted to throw up whenever I saw

So as mentioned above I used someone elses update cd (which was for an MKIV) and messed up my whole system.
After making the cd, I put the cd in my drive. It stayed blank for about 30 seconds until I see "Press OK to start update" I was in shock.. Then I saw this

Then this:

Of course I hit another bump in the road

No fear. I found a link to a copy of a "key cd" (some MKIII's need this to complete when doing a rather big update) .. ----> Heres the link http://www.e38.org/nav/BMW_NaviSoft_KeyCD_Clone_cd.rar[/URL] ...
Once it was complete the system rebooted and I see a BMW logo on the screen and all of a sudden I see this

WOW! What an upgrade. For years Ive been wanting to do this. Now I have split screen and updated graphics Thanks to those who helped me out
