hi i am driving a e60 from 11/2003 with navi business, can i use this navi software to upgrade my navi to work with the new maps from 2-2007

i burned the image with acohol but when i insert the cd to the dvd drive where the map-dvd was i just does nothing
it doesn't recognize the update cd

is there a way to find out what version of navi soft i have ?

is there a certain way to burn the cd or a certain way to put it in the dvd drive of the car ?

i burned the cd at maximum speed of 52x could that be the problem that the drive does not recognize it ?

hope someone can give me a hint

thx a lot

greetings ilovebytes
