hi everyone. 1st post here. i know you guys are masters of the bmw nav system!, so i hope you can help me.

i have a late 2002 530i sport 'champagne' edition. it has the mkIV nav system and version 30 software- 4/1-91. all upto date.

my question is that ive read lot of people say that the splash screen logo shows when they open the drivers door. well, mine doesn't!
the screen seems to try to do something but it remains blank
(a slightly different shade of grey but still blank).
it only shows the logo when i turn the key and then it sometimes just goes straight to the menu without showing the logo at all. it all seems very random and i cant work out when the splash screen is supposed to show.
i have perosnalised the logo but it was doing this before that aswell, so i dont think its anything to do with that.

anyone have this problem? or know how to fix it?
appreciate your time.

Cheers.
