How to hack the 2006 Honda Civic Navigation System
Splash Screen
1) Copy files from the DVD to your computer

You'll need a CMD window to repeat what I've done.
To open a CMD window, Go to the Start Menu and select Run...


Type cmd
Click OK
You'll see a window like:

We need to make a directory to do our work in.
Type the following:
    md \nav
    cd \nav

This will create a directory named "nav" on your hard disk.  It will then change the current directory to "nav".
Note: be sure to use backslashes not forward-slashes.


The files we need to copy from your DVD are:
-rw--a-    5182015  23 Aug 2005 04:11:55  06AVN.bin
-rw--a-   21832335   5 Feb 2006 08:44:39  06AVN2.bin
-rw--a-       1296  30 May 2005 22:15:04  A0000_00.MNG
-rw--a-        381  26 Apr 2005 03:46:21  DCA0.REG
-rw--a-        272  23 Aug 2005 04:28:55  PRG_INFO.MNG
-rw--a-      76288   4 Feb 2005 00:06:14  UPDATE_APL.exe

Put your nav DVD into your computer's DVD drive.  I'm guessing that that will be the D: drive, but it might not.  It is up to you to know what letter is assigned to your DVD drive

now, type the following into the CMD window and then press Return.
    dir d:06*.bin,d:a0*.*,d:dca0.reg,d:prg*.*,d:update*.*

Please note that all the round letters in that command are the digit Zero, not the letter Oh.
If you don't see 27,092,587 bytes then something is wrong.

Execute the following five commands:

To prove that everything has worked so far, type the following command:

If you do not see 6 files which add up to 27,092,587 bytes then something has gone wrong.

Now you have the files which must be present on a new disc.
2) Modify the files on your computer

Download and open bysin.zip

Select Bysin.exe and CECompressv4.dll by holding down the CTRL key and clicking once on each file.
Click the Extract button.

Type C:\navhacker into the space on the left,
then click the Extract button.
Now close WinZip (or whatever program opened Bysin.zip for you).

Return to the CMD window.
Type:
    cd \navhacker
    dir
    copy \nav\06AVN2.bin


Use bysin.exe to extract Opening1.bmp from 06avn2.bin:
    (it will take about 30 seconds)
    bysin 06AVN2.bin extract Opening.bmp

Verify that everything has gone as expected:
    dir /s


Drag and drop \navhacker\06AVN2\Opening1.bmp onto Internet Explorer:

Put a copy of the bitmap you wish to use into the c:\navhacker directory

I use kilt.bmp.
It is 480 by 234 pixels and 256 colors.
It was created in Paint Shop Pro.

Download and open 8to16.zip

click on 8to16.exe
then click the Extract button

Type C:\navhacker into the space on the left, (it may already be there)
then click the Extract button.
Now close WinZip (or whatever program opened 8to16.zip for you).

verify that things are still going as planned:
    dir /s


Use 8to16.exe to make a compatible bitmap from an image of your choosing:
    8to16 kilt.bmp Opening1.bmp

verify again:


Drag and drop NEW Opening1.bmp to Internet Explorer to prove it worked.


Use bysin.exe to replace Opening1.bmp in 06avn2.bin:
    bysin 06AVN2.bin update Opening1.bmp Opening1.bmp

06AVN2.bin should now have the current date and time.

Copy 06AVN2.bin to C:\nav

3) Burn and install a disc
