UPDATE: 2008 Honda Odyssey Navigation Screen Hack
I received this information from Brian who was successful in completing this mod on his 2008 Odyssey:
I was able to Hack my new '08 Odyssey Navi with help from your blog and other sources. I used the new DumpNavi "bysin.exe" http://guicide.com/cars/2006civic/nav/hacks/Bysin.zip instead of CEbin.
The '08 has a couple other bmp files you have to modify to match your picture. I had to modify move and match these four files:
Just thought I'd leave that bit of information for anyone else trying with an '08.
ORIGINAL POST FOLLOWS:
I originally posted my success with modifying the startup splash screen on our 2006 Honda Odyssey navigation system here but I never actually put down all the steps in one place. Until now :0)
My thanks go out to the people at OdyClub and AcruaZine whose threads I followed to get inspired to do this modification. Special thanks to sejong over at OdyClub, who pointed me to the correct file to start with and answered my questions when I ran into problems. I wouldn't have been able to complete this modification without his help.
Your mileage may vary: By posting this here, I am simply describing what I did with my own 2006 Honda Odyssey Touring. This information may not apply to different model trims or years. I can make no guarantees that this will work on other vehicles nor can I guarantee that doing this mod will not turn your navigation system into a brick. If you are unsure how to create a batch file using Notepad and how to use the Command Line prompt on your computer, you may not want to attempt this mod.
Software that I used:
- HVCT - To convert the image to the proper format.
- CEbin - To update the original bin files from the navigation disc. Another program mentioned on the forums dumpnavi didn't work for me. (There is an "Improved DumpNavi" that may work and may be easier to use to update the .bin file but I haven't tried it.)
- A program to burn files to a CD.
I copied the 9 bin files from the Honda Navigation DVD (v4.31C) to the hard drive on my computer. Only one actually needs to be modified, but I copied them all anyway.
I also copied these four additional files as well:
I used a paint program to create the picture I wanted to use for the opening splash screen with the following specifications:
- 24-bit BMP format with no more than 256 colors
- Dimensions: 480 x 234
I used the HCVT program to convert my 24-bit bitmap image to the proper format required by the navigation system. It converts a 480x234x24-bit bitmap to a 16-bit bitmap of the required 224,712 bytes. I then renamed this file as Opening1.bmp
I used CEbin to replace the old image in the bin file with my new image. To operate CEbin I created a replace.bat file using Notepad with the following text:
image 05Touch2.binStep 6
replacefile Opening1.bmp Opening1.bmp
Using the command prompt, I typed this command:
cebin replace.batThat updates the 05Touch2.bin with the new splash screen file called Opening1.bmp
There is now a new file called 05Touch2.new in the directory. I moved the original file (05Touch2.bin) and renamed this new file to 05Touch2.bin
I used a CD burning program to copy the updated .bin file plus all the other .bin files as well as the other 4 files (in Step 2) onto a blank CD-R.
Step 9: Out in the garage
I put the key in and started up the nav system. I didn't have the engine running because I was confident the battery would not die.
Step 10: Updating the navigation system
When the nag screen came on, I pressed the MAP/Guide + Cancel + Menu buttons at the same time and held it for about 5 seconds. After a little "beep," this screen appears:
I pressed "Version" and saw this screen:
Then I opened the door to the Nav drive (which is under the driver's seat), ejected the disc, and replaced it with my custom burned disc. LEAVING THE DOOR OPEN, the system attempted to read the new disc. I waited until I got this screen:
I press the MAP/Guide + Cancel + Menu buttons again to go back to the Diagnosis screen. I pressed Version again.
Next I pressed Download and saw this screen....
...and then this one after the system recognized the disc:
It took about a minute or two for the progress bar to finish. Once that's done, the system reset and I saw my custom splash screen. After a little while, I got the same error message I got before about the door being open. So I took out the burned CD and put back the original Nav disc.
And that's it!
