I have a 2003 M5 with what I understand to be a MKIV (shows DVD on reader in trunk). However, prior to attempting to update, it showed my firmware to be "SW 3-1/63".

I downloaded FW V32 here: http://www.xoutpost.com/electronics/navigation-system/50902-v32-has-been-released-now-available.html

I then burned a CDR at 1x using CloneCD. Put it in the nav, gave me the usual screen with red text "CD-ROM in drive, installing sw." Then screen went black and flickered every few seconds. Gave it a good 10 minutes and never changed. All functions still work. I can listen to music now and buttons work but screen will not show, still just flickers. In addition I could not eject the disc. I tried the harness pull trick and the 3 minute hold. Had to take apart and move the gear myself. Screen still blank. I tried burning again with imgburn on stock settings which now looks like I should have changed the mode or something. But that did not do anything but did eject at least.

Can someone please help with a fix?

Thanks in advance,
Jeff
