2001 Navigation software
 

Can anyone help me with this? I have a 2001 911 with a factory installed navigation system. The software is stored on a CD which you have to slip into the disk drive system in the dash. When I inquired about getting an updated version of the software with updated maps and I was told that this is not possible, that new(er) models work with DVD's and that the original CD was the most recent option. Does anyone have any options?

Thanks

Pete
