Updating Navigation Software - Help Needed

Hello All,
I am new to the forum and my car is a few months new to me. I would like to update the Navigation system software. I have downloaded v28 but I had a question before I put it in the car. Is there an upgrade path or is every version inclusive of the previous release? Do I need v27.1 first?
I don't know what version I am running but I don't have perspective view on my nav. Where can I locate the version number? The only information I have is that it is running 4-1/50 and the DVD disk is 2005-2.

I know I have to update the maps after I update the software but I am trying to make sure I am not going to screw up my car and then I have to make a trip to the dealer.

BTW, it is a 2004 X5 4.4 production date 10/03.

Your help is greatly appreciated!!
