Hack the nav - enable trip computer and AC

Sorry man, I just realized I e-mailed you the wrong files. I sent files from 4.13 and not from 4.20.

Mechanic behind keyboad.............never a good situation.

Do you want me to send the proper files.....??

Big file, even after zip.

No worries about the files.

I had to go to the dealer for another problem (VTM-4 wouldn't engage) and of course I had to deal with the non working Nav system.

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.

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

Unfortunately, as far as I can tell, the info on the tsx.acurazine.com you mention is not accurate for the ridgeline navi system. It does NOT work with the Ridgeline. The files on the disks are not the same as the ones listed in the procedure, and the "version" screen does not list any of the info needed to hack the system using this methd.

Yes MENU CANCEL MAP gives you a setup screen with file names, and I can get to the "version" screen easily, but none of these files are listed.

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

Until someone figures out which .bin file we are looking to modify, it will not do any good. Contrary to many peoples belief, the files on the ridgeline are different than the other systems listed on tsx.acruazine.com and the dumpnavi program does not work until I know what .bin file the ridgeline uses.

Do you know this info? Can you give me some procedures? I would like to try.

The TSX does not use the same navigation system as the Ridgeline. The Ridgeline shares the navigation unit with the Odyssey and the Acura RL. The Acura TSX and TL use a system that's one generation older.

I strongly recommend that you do not follow the link given. That information is incomplete and after receiving donations the author of the hacks disappeared.

The data does not apply to the Ridgeline and is of questionable origin. Beware.

[csimo]

And they said it couldn't be done... but it is.

Here are the trip computer and A/C control screens on the Ridgeline nav unit. Haven't got the A/C screen to actually work.

Will try and get better pics.

One more...

Before anyone asks... I am not at liberty to say how this was done. Still a work in progress and I have only been given permission to demonstrate that it is possible.

I really do wish I could give details, but I can't. Sorry!

[Mountain Ridge]

Thank you, and who said it could not be done?

If you will be able to share this with fellow ROC mambers at some point in time, please let us know if you need any financial assistance for such.

CSIMO is the man.

Can anyone see the title on the XM was that a coincidence (UP YOURS) LOL, But one the other hand CSIMO YOU DA MAN cheers for all of the hard work, as far as the donations thing goes well you all seen what happened last time, but if your going to charge then tell us (me) up front i would gladly pitch in so dough, for a working trip and once again your hard work is appreciated
