I have a 2004 M3 and I'm wanting to upgrade my navigation. I'm really confused about all the jargon being used, and would really appreciate it if someone would take the time and help me out. I downloaded the v31 update and installed it in my car fine, but now I need the actual updated navigation dvd. I just saw that the v32 update is out, so should I download that? Please do not tell me to search, because I have been for days, and have burned multiple dvds that have not worked. I'd really appreciate the help. Thanks.
