Hi all,
Here's the entire procedure for changing your spoken language, written language and logo's, including references to where you can get the correct files, and step-by-step procedures for each step.
1. Download the new image (eg. v27.1). More info in the "BMW Navigation System FAQ" thread:
http://www.xoutpost.com/articles/all-...ystem-faq.html
2. Download CRC24.exe from the HackTheIBUS group (first subscribe, etc.):
http://autos.groups.yahoo.com/group/...iles/Software/
3. Downloaded NavTweak from the following thread:
http://www.xoutpost.com/156049-post1.html
4. Extract NAVBOOT (\V_2\RR\0101\BMWC01S\app_sw\) from the image using UltraISO. More info in the "Editing Splash Screen" thread:
http://www.xoutpost.com/102790-post161.html
5. Extract the language module you'd like to use (for instance Lng_Hollands) from NAVBOOT using NavTweak
6. Open the language module with your favorite hex-editor (for instance UltraEdit –
http://www.ultraedit.com) and change the language name (for instance "Lng_Hollands") into the language you would like to replace in your navigation system making sure the length of the name is the same (for instance "Lng_Deutsch." with "." being "00" in HEX to keep the correct length)
7. Save the language file and calculate the CRC using CRC24.exe. Then replace the CRC24 HEX values at the end of the language file with the values from CRC24 – please note that CRC24 then says "OK" when you check the file again
8. Replace the old language module (Lng_Deutsch) in the NAVBOOT file with the NEW language module (Lng_Hollands) using NavTweak - this now worked (before changing CRC in step 7 it did NOT work, due to a CRC error)
9. Replace the original logo with a custom logo using NavTweak (GifExtractor works too, but you lose some of the traffic symbols with larger logo's). Save the new NAVBOOT file
10. Replace the new NAVBOOT file in the v27.1 image, and modify the languages (these are the spoken languages). See the following thread:
http://www.xoutpost.com/102581-post5.html
11. Save the image in your favorite format (I use ISO) and burn it with your favorite burning software (I use Nero) on the lowest speed, see the following thread:

Hope this helps all of you as a good guideline to modify the image! Possibly this post can be made sticky as it summarizes a lot of links needed to make all modifications currently possible (right?!).
Regards,
Nika.
