i have a 97 740i..i had version 1-1/7.1 before and i tried to load version 28...after i installed it a black screen sayin your installation was succesfull software version 8.0...press ok to continue...so i did this and went back to settings and my version says 1-1/7.2....i thought version 8 would show up as something different and there is no change in my menus or the navigation..its exactly the same as before...so i tried to load version 27 but it wont let me...everytime i put that cd in the black screen that says version 8.0 is installed comes up and it wont let me do anything else...does anyone know whats going on with this??
