2002 X5 with mkIII 3-1/63 Help

[jonnyvogue]

Hey folks,
I just bought a 2002 X5 with this MKIII and the version of the software is 3-1/63. I am pretty sure you people have talked about this before but I am always at work when I am online and I really cant afford to read through 9000 pages of these forums. Can anyone please point me in the right direction as to where I may find an update for this dinasour MKIII with a little instruction? I read something last night that gave me V-32 upgrade but when I downloaded it, the file was an ISO which I put on a CD and the MKIII spit it out repeatedly!

Please help. My NAV says that mapping for the town I am currently in does not exist.
