Will these instructions below work for my 2008 navigation system? I want to change my background picture... Or will these instructions only work for older navigation versions? Thanks

This program is used to list, extract, and modify files
contained in an XIP BIN file located on Acura/Honda
navigation DVD. This system has been tested on the
TSX. Use at your own risk.

Some of the things I have been able to modify are:
- Changed the background picture to my own
personal image.
- Removed the "nag screen" at the beginning
screen.
- Change some of the words that pop up.

Here are some step-by-step instructions on how to modify
files in your navigation system. It requires a DVD-ROM
drive and a CD or DVD burner.

1. At the main screen of the navigation system, hold down
the Map/Guide, Menu, and Cancel buttons for 5 seconds.

2. Hit the "Version" button on the touch screen.

3. Hold down the Menu button for 5 seconds.

4. Write down the filename next to the words "Loading
Filename" (ex. BNHN404A.BIN).

5. Open your trunk and find the DVD player attached to
the navigation system.

6. Push down the front plate and eject the Navigation
DVD-ROM.

7. Place the DVD in your computer and copy all 9 BIN
files onto your hard drive (should be around 104 MB),
this includes:

BN2HH12C.BIN
BN2HH110.BIN
BN2HH120.BIN
BN2HHMLD.BIN
BN2HN12B.BIN
BN2HN18B.BIN
BN2HN380.BIN
BNHH401A.BIN
BNHN404A.BIN

8. Use the dumpnavi tool to extract the files on the
BIN file that was on your car, ex:

dumpnavi BNHN404A.BIN extract

9. The files will extract to the directory associated
with the name of the file.

10. After modifying the files, use the dumpnavi tool
to update them to the BIN, ex:

dumpnavi BNHN404A.BIN update Back.bmp
dumpnavi BNHN404A.BIN update navi.exe navi-nonag.exe
dumpnavi BNHN404A.BIN update Diag.exe

11. Copy the modified BIN file, including all other BIN
files (9 in total) to a blank CD or DVD.

12. Insert the origional navigation DVD back into the
DVD-ROM in your car.

13. Start the car normally, and at the main navigation
screen hold Map/Guide, Menu, and Cancel for 5
seconds once again.

14. Hit the "Version" button on the touch screen once
again.

15. Take the origional navigation DVD out of the car,
and replace it with the CD/DVD you just created.

16. Hit the "Load Disc" button on the Version screen.

17. It should take about 20 seconds for your car to
load the new BIN and reboot. Once that happens,
take out your burned CD/DVD and put back the
origional navigation DVD.

18. If anything goes wrong, remove the ground to the
battery for 30 seconds with the origional DVD
in the car. The old OS will load back on the
system.
