I use UltraIso, it will let you extract the navboot file from the v29.mds file and save
back (the new image) to a v29.iso file (ready for cd burning)

Install UltraIso,
Then run UtraIso
File, Open "v29.mds"
Navigate to "V-2/RR/0101/BMWC01S/app_sw" in the now open image.
Drag and drop the navboot out of the image onto desktop (or sub-dir)
Open navtweak
File, Open "navboot"
Select the 2nd tab (images)

For sky select romicons #8 and right click replace, (with your choice)
For splash select rombitmaps #14 and right click replace, (with your choice)
For 3d icons rombitmaps select rombitmaps (you get the idea)

Then save the navboot (keep a copy of the original safe).

Then drag and drop into the open UltraIso session (back where you found it, "V-2/RR/0101/BMWC01S/app_sw").

The nav unit doesn't allow it to "update" with the same software as already installed.
So you have to fake the SoftwareVersion.
do the following: also extract the 2 .tbl files from the directoy:
<drive>:\V_2\RR\0101\BMWC01S
Open it in an HEX editor (like Freeware, PSPad http://www.pspad.com/en/)

In the first line you find: 30 39 31 30 This means: 0800 So: Software-Version 08.00
Just edit the last 30 to 31 and you nav unit will think it's a new Software Version and you can
update your V29 without prior downgrade to V28

The next time you update, you can edit it back to 0800 then 0801 again...

Save the UltraIso image as v29.iso, then burn a cd ad 1x speed.

Thats it.

Hope this helps

^ that does help me a lot, I've only been messing with it in my spare time (which hasnt been a lot lately). I've got her updated to 29 and perspective mode turned on, but have yet to actually tweak her...

I have a question though...

Since turning the "accept" screen off seems risky, can we change that screen? Replace it with a picture, or at least put something else in there that'll make people laugh or something? Just thinking out-loud...

I would love to try and sit here and read through nine pages on how to download these into your nav system but im at work and cant, can anyone be kind enough to tell me how i can do that. get images into your nav system, thanks much

Just read the first post on this page. I've yet to try the instructions, but they seem fairly clear. I plan to try this tonight or tomorrow...

Good Luck!

Thanks JOHN ! very helpful.

X5 World splash screen

Is there anyone who could burn a cd for me with version 27 (for MKIII) and my logo cause I find it to risky to do it myself...
I could make your splashscreen in return (i'm a graphic designer)

http://www.m75.be/bmw/smashworld.gifhttp://www.m75.be/bmw/smashworld2.gif

Would also be neat if a programmer could add a function for selecting multiple splashscreens in settings menu. not neccesary for me.

How do you guy save the splash screen image from Photoshop to the specs, ie. 96dpi, 8-bit GIF?

Thanks in advance.
