MKIII navigation problem
 

I have a 2002 E46 with mk3 16/9 navi , it was 3-1/30 but I updated it to 3-1/63 with nav OS 27. Then I decided to make custom splash screen with navtweak , I changed only the .gif files, burned the new image and thought I did it , but when I put the disk in the navi CD it went to endless circle, the screen went black with some flashes . I remove the stucked disk thanks to this post . I put the original navOS27 cd (without changes) but nothing happens. The screen now is black with this flashes.
Please tell me what to do. Did i killed my navi ?
thanks
p.s. sorry for my english.

:thumbup: I made it
I put the original CD again after some time and the navi runs again .
