The topic of hacking the Honda Navigation system has been thoroughly explored on Acurazine.com
http://tsx.acurazine.com/forums/showthread.php?t=21434 and any future RTL NAVI hacking should start by thoroughly understanding that thread.
Things of interest:
You can customize the Boot splash screen to almost any picture you like and people now have libraries of fantastic pictures.
You can try using the Acura hacks to remove the lawyer screen and change the OK text to GO. It might not work but it is not a catastrophic failure as you can easily reload your original DVD code.
Pressing MENU, CANCEL, MAP for 5 seconds gets you diag screen and version menu will allow you to load custom code from a CD (no DVD is required) when the file names are correct. Loading is into flash.
BTW you NAVI has a PCMCI slot next to the DVD slot which appears to be for downloading diagnostics logs into flash cards or maybe where you have been and how fast you've driven to the traffic courts.
Further hacks are very difficult as this is windows CE code written in C++.
The diassembled code is posted but it is not for the faint of heart.
Enjoy

The dealer said that there are a few Nav systems that have a flaw that causes the unit to quit recieving input, and that it looks like mine might be one of those.
The net result is my NAV system had to be replaced and I'm without my new truck for a day or two (though mostly that is due to the dealer wanting to do a through check of the 4WD).
I'm done experimenting for now. When we have more information from a SH4 / Windows CE programer to look at the program flow of the RL vs the Ridge ROM images and perhaps reverse engineer the right "bit to twiddle" I might look again....after someone else has done it 
I'm still holding out hope that if we make enough noise Honda may enable the trip computer with a future release of the nav DVD.  |
