Hack the nav - enable trip computer and AC

[outtaline]

Gotta have all the details. The suspense is killing me. By all means, post the info!!!!!!! And as always, a big thank you!!!!

I'm very interested in the outcome. I recently purchased (2 weeks and loving it) a 07 RTL w/nav and stupid me didn't even think that a truck with everything the Ridgeline had on it wouldn't come with a simple thing like a trip computer. When I got it home and realized it I was furious. Contacted the dealer and got the news. Next step was search the internet for answers. That's how I found ROC. Love the forums and all the info. Thanks for everyones time looking into this. Please keep us posted!!

Would love to have the hack to upgrade this new truck. It would be nice if we did not need to hack it and get this from Honda. Like that will happen!!!!
Please update us to keep this post current.

Bysins' no-nag hack is for '04 vehicles only. The Ridgeline's binaries don't include an executable called navi.exe

I appologize for my late posting- in the past few weeks I have found out more about embedded Windows CE/Platform builder, and Alpine's proprietary navigation system than I ever wanted to know.. I've gone in many many directions and spent so much time on this and let me tell you, its been very frustrating.. First let me say this- I have not yet rid myself of the pesky NAG screen, but a hack will be forethcoming VERY soon- my confidence stems in a breakthrough I made only today-- but a picture speaks a thousand words, so look at this:




Why is this important you say? Because any prior attempt at hacking HMIManager.dll (for '06 & '07) to get rid of the nag screen resulted in the car rejecting it upon upload. Basically, I found out the flash program is doing a 8 or 16 bit Checksum on HMIManager and perhaps a few other modules-- The backwards "This" in the above picture retains the original 16-bit checksum of "B171" because a low level checksum cannot detect bytes that have been re-arranged. (Note, this is the checksum of the original 07touch2.bin romimage-- if you've changed your splash screen, the checksum will be different-- the flash program doesn't checksum the entire BIN file) Now, if you replace the word "This" with empty space or something, the checksum will definitely change. So ultimately, the key is to write a hack that keeps the correct sum OR get rid of that check entirely. I haven't attempted this yet because I was completely stuck on the car rejecting all my modified hacks.

Also note- HMIManager is a module that is located between 4 different sections of the BIN file, so extracting it and re-inserting it is not really an option. (I've talked to a few different programmers about this) But, just hex editing the main bin file (07touch2.bin for me) directly will suffice because the module is not compressed. Anyway, let me know your thoughts.. I'm excited about seeing this thing through to the end.

Oh yeah- just so you know, I actually have an 07 Acura TSX- but obviously, it's the same system as the ridgeline. I posted to this forum because there seems to be a lot of people on here that know what they're doing.

Thanks for the work on this. On the 06 Ridge, the nag text is in HMIUtility.dll in sjca2.bin. I haven't tried any substitution yet, or identified the call or OK button wait routine.

seems to be a few techies here. i've read this whole thread and i'm impressed.

wondering if you can possibly help with a similar situation on the 07 Acura RL base model. it isn't that Acura deleted trip computer functionality, that is there, it is that Acura decided only to activate the Navi system on the 07 RL's that have the Tech package which is a $4k option (unlike the 05 & 06 RL's that all come standard with Navi).

i normally wouldn't complain, except that in the RL all of the equipment necessary for the Navi is there: screen, buttons, GPS antenna, DVD-ROM drive in trunk, etc... You can even push a "Compass" button (on the Navi RL's it is the "Map" button) and in the base RL you can see GPS coordinates including Lat, Long, and Altitude.

So other than one button be labeled differently, and not having a Nav DVD disc in the player in the trunk (there is a Navteq GPS CD-ROM disc instead), I can't see any reason why Navi could not be enabled by some kind of "hack" on the 07 Base RL's.

Is anyone willing to help?
