Good morning ccfj1
Wow what a response. Thanks for all the good things you do on this forum.
When I started out, I had V26.
Since I did not fully understand all the pre-requisites I just downloaded
“M logo Splash, modded Sky OEM colour set 1 and Night/Blue scheme colour set 2 M_day_night_OEM_Blue”from the beginning of this thread.
This did not work (of course, I know now) so I tried to burn the image again with “ImgBurn” as recommended. This still did not work and I somehow ended up with a blank screen on the unit.
Before I started panicking too much, I went back to the beginning of this threat and downloaded:
“1: OEM Splash, OEM Day mode, Modded Sky, Custom Night mode (col_set 2 wide and split, but OEM colours) and Day/Night menu text. v31 Night OEM 1010”
Then I burned it with “ImgBurn” and put it into the drive and it did and update. It was very fast and I had my screen back.
Now, since all was good again, I checked the version number and it read: 4-1/01. I looked this up on this table: http://www.xoutpost.com/articles/all-bmw/navigation/9458-bmw-navigation-system-faq.html and figured that it is maybe just a version higher than V31.
I thought this is ok, since I got the image from this thread and tried again to update with “M logo Splash, modded Sky OEM colour set 1 and Night/Blue scheme colour set 2 M_day_night_OEM_Blue” which failed again.
I am sure I am doing something wrong, but I am new and I have a hard time reading thru all the thousands of posts to catch up.

Thanks
