Hello, I saw that there are OS updates for MKIII navigation systems on this site. I contacted the dealer and he had no clue, he was thinking that I was referring to the map updates.

I have downloaded V28 from this site along with CD Key. My nav system states it is 3-1-30 which means it has a version 17 on it. Will the V28 work? or will all of this mess things up..... is there a link to where I can ensure that i have downloaded the proper version from my navigation system?
