bmw MKIII cd stuck, black screen, wrong disc burned, eject failure = fix

[nex]

Hi all

I just want to share my fix with all you here since last night i've tried to upgrade my e39 navi with wrong burned cd...
After failed upgrade my navi screen was black, it flashed a lot but i coul listen cd,radio etc.. and every minute or two it shuts it self.
Also i couldn't eject cd from unit!

I removed navi, opened it, manualy removed cd, put back correct cd and it flashed it back to even higher version, i think 22 or something...

I belive this could be helpfull for somebody...
