Hi, I am pretty clueless to this stuff and would really appreciate any help I can get. BTW - thank God for this forum.
I live in Pennsylvania (US) and have a 2002 x5 if that matters at all. My nav system seems to be way outdated even compared to friends who have 2006 models. I've already spent $130 to buy one set of map updates 2 years ago and really don't want to again with the system I currently have.
When I go under Settings on the top right of the screen it reads:
SW 3-1/50.
Is there a certain version that I can only upgrade to with this system?

Can someone please help me upgrade. Do they do software updates at the dealership?
