Hi,

Sorry in advance if this subject has been mentioned but I am a newbie and in need of some advice. I purchased a 2004 X3 3.0i Sport 3 weeks ago and want to upgrade my sat nav to latest software and maps.

My Operating System - SW 4-1/30
My software is - 2004-2 (V23)

are these the latest upgrades?
Operating system - V30
Software - 2008-1

Please help with these questions:
Can someone please explain the difference of the OS and Software?
Is it possible for me to upgrade and do I need 2 discs to upgrade OS and Maps?
Is it just a case of getting these latest discs and loading into DVD/CD player?
What will be the benefits of upgrading?

I have also been reading about other upgrades i.e. speed camers, petrol statons etc etc anyone else know anything about these extras?

Thanks in advance for all your help
Dan
