Hi guys i m new here and i need help:
i have been following up the threads about the software upgrades and decided to try it... i have BMW e46 320d 2003
i had the following display on my nav screen - 4 1/20 which i'm assuming i have MKIV version 22.1
i had downloaded v31 burned with alcohol120 at slowest speed 8x, turned ignition key in position 1,poped the cd in,screen showed message-warning not to turn ignition key off for 6 minutes (until CD comes out) then screen flickered for a few seconds and then went blank, I sat there waited for 10 minutes, nothing... now the screen is blank,radio and CD changer works!

Can i reset navi to companys settings(previous FW)?
Can i get some help, please....
