thanks for all the info, my local dealership had told me that these software versions are for the newer models and not for the '04? is this correct information? is it a case where they are not "officially supported" for the '04 but they work on it? he also seemed be confused whether i wanted the new firmware or the streets, i told him I was more curious about the perspective view/etc and he said that was not possible on a 2004 X5 only the newer ones.. is this true?

if i were to do it on my own, would it alter my warranty in any way?
