i have a 2004 m3 and i just downloaded the 2009.1 high version for my mk4 system. the filename was 'bmw_navi_2009.1" file size was 4.07gb and was in .mdf .mds format.

i used imgburn at 1x speed on memorex dvd+r media. i am currently running v31 as well with the M splash screen and female british voice (do i need to upgrade to v32?).

now is there something i need to do to 'load' the dvd map into the car? i know there was a special procedure for loading firmware. all i get is 'incorrect dvd/map"
