Easy:
1. Get NavTweak v2.6
2. Open the file on the OS disk you wish to edit - navboot for MkIV, usw_load for MkIII
3. Replace image with new image (right click on image to replace)
4. Save file back to OS disk
5. Load in to vehicle

There's nothing wrong with the GIF image, it looks the right size.

Ok, first problem.... I downloaded the Navtweak (there is a link in the above sticky). I unzipped it. When I go to run it I get the following error "failed because libgdk-win32-2.0-0.dll not found".

Can you tell me what I am doing wrong.

Thanks all, I know this topic has been beat to death, but it is very new to me and very confusing.

Correction: I refered to "Peter" as the creator of the custom splash I want to use, I see it was actually "Paul Martin"

Sorry about that.

You need the GTK run time environment

Read this:
http://www.xoutpost.com/navigation-sy...-navtweak.html

Ok, getting there, but still having a problem. Let me tell you what I have done so far.

1. Downloaded the V27.rar update
2. Un "rar-d" it with Tugzip
3. I now have (2) files: V27.mdf (huge file) and V27.mds (only 1kb)
4. Downloaded NavTweak 2.6
5. Downloaded GTK Development Environment (not sure if I even need)
6. Downloaded GTK Runtime Invironment

So now the NavTweak does open up (yeah) but when I choose File, Open, and select either the .mdf or the .mds I get "Unknown File Format".

Also, I found Paul's original file that has the i-drive logo. He has it saved as a "wave" file and said to change it to a zip. How do I do that? He said the file is really big thats why he sent it that way. Or am I ok with just using the gif image that I right-click saved from one of his posts.

Man my wife thinks I'm nuts and is gonna kill me if I mess up her Nav. But if I'm gonna do the upgrade I want the custom splash as well.

Thanks again for taking the time to help me.

You've done everything right so far.

The MDF file is a CD image file. You need to use eg MagicISO to open the MDF file and view the contents of the CD. Then you can extract the navboot file from the CD, change the GIF inside the navboot, and save back to the CD image

Then create a new CD using the CD image - this is the OS software CD

Then load the new software in the car by inserting the CD in the nav drive.

Do you have a Mk3 or Mk4 nav?

Ok, I'll try that and report back.

I have MK IV.

When I make the changes and I'm ready to burn my final CD, do I burn both mdf and mds files or just one of them.

Again thanks a TON. I would have given up without all of your help.

Good
No, you don't burn the file to the CD like you do a file to a hard drive.
The MDF _is_ the CD image. You have to use a program like MagicISO to burn a CD using the image file (that's the BIG file)

Get MagicISO to see what I mean

OH BOY, I THINK I DID IT!!!!!! Let me tell you what I have done and you tell me if it sounds correct.

1. I couldn't find MagicISO so I downloaded and used UltraISO.

2. I used UltraISO to open up the saved V27.mdf file that is on my hard drive.

3. Once the V27.mdf file was opened in UltraISO I found the V_2 folder. I opened the string V_2 RR 0101 BMWC01S app_sw. I then saw the file "navboot".

4. I right clicked on the navboot file and extracted it to my hard drive.

5. Once the navboot file was on my hard drive I closed UltraISO and I opened NavTweak. Using the "File" botton in NavTweak I found the navboot file on my hard drive and I opened it. Clicked the Images tab, then the rombitmaps tab. I scrolled down to item #14 and found the === BMW ===. I right clicked my mouse on the line and selected "replace". I selected the i-drive logo.gif that I saved from Paul Martins previous post and was now on my hard drive.

6. The new logo was now in place. I then went to the File button in NavTweak and slected "save" and re-saved over the navboot file on my hard drive with the revised one I just changed.

7. I closed everything and then went back into the navboot file just to double check my new logo was there, AND IT WAS! Un-friggen believable.

8. Now the revised navboot file was still on my hard drive. So I open UltraISO. I found the V27.mdf file on my hard drive. Again found the V_2 folder and went down until I found the navboot file. I then took the revised navboot file that was on my hard drive and copied/replaced the navboot file that was in the .mdf file.

Does that sound correct to you? If not let me know what I might have done wrong or forgotten. If it is correct, can you please just walk me through the burning of the final files onto a CD-R.

1. Can I use UltraISO to burn the new CD-R? Or do I need to use the Alcohol120% program.

2. What files do I burn to the disc, the .mdf, the .mds or both of them?

3. Lastly, how do I change my burner speed to the slowest setting (x4)?

Thank you, thank you, thank you for ALL of your help!!!!!!! I can't tell you how much this means to me. I'm not and idiot, it's just that I have never done anything quite like this before.

Let me know about burning the CD-R questions.
