When is back.bmp displayed on the Navi. Does it only appear when the car is first started, or is there a way to keep it there?

Thanks

again... is the project to reverse engineer using dumpnavi is thru? im sure many would love to see the nag screen completely skipped... any answer? thanks

You need to lower the number of colors to reduce the size. Read further back in this thread for the exact number. I think it was 173 colors.

Hello Everyone,

Would someone please email me the Navi.zip file as I can't find it?

Thanks in advance.

Thank you very much azure.

Chita79:

This was bysin's project. Unfortunately, he is MIA and has been gone for quite some time. We probably won't see any more progress. At this point, you can only swap the background image (cannot disable the NAG ok button).

It's fairly difficult to reverse engineer the NAVI software. Bysin had some experience from hacking the DreamCast (similar hardware: sh4 cpu) that probably helped him figure out as much as he did. Hopefully, someone will carry on where he left off, but there probably aren't too many people who have the skills and time to do it. Check other forums (the TSX forum has a similar post) to see if anyone has tried and keep us posted.

I'm a senior at Georgia Tech studying Computer Science. Unfortunately, I don't have much experience reverse engineering or hacking. I took a stab at the Navi S/W last weekend, but I didn't get too far. Using IDA Pro Advanced, I was able open and dissassemble navi.exe. But there is a lot of assembly code to decipher, and its PITA to make sense of. I'll keep looking at in my spare time, but I don't expect to make much progress. This is one of my busiest semesters, so I don't have much time to spend on it, and again its a PITA to decipher the assembly code.

Chita79

sounds good...(damn... i wish i woulda listened more carefully in my Assembly class back in university) :P

positron, please Send me a PM so I can reply and send you my Email address.

If you can email me those 2 Zip Files I can rehost them on my site since bysin's seems to be offline again and no word yet from Soopa.

As for the rest of you...

The current status appears to be this.
Bysin is no longer posting. Also his website is no longer working to download the files and instructions from.
So his effort on this project can be assumed to have come to an end.
I will try to get the files from anyone who has the latest copies and rehost them for all.

What this Mod DOES do:
- Replaces the logo that appears when your NAVI screen first comes up. The default is the world.
- During extraction, you can also Hex edit navi.exe to remove/change the TEXT on the Nag Screen, including the buttons.

What this Mod DOES NOT do:
- Change the Nag to a picture background
- Remove the requirement for pressing the stupid nag button to continue
- Change any other screens other than the ones mentioned above.

If you have any of the Files or HTML Pages from Bysin's website, please PM me and I will get them rehosted.

So would it be possible to Relocate the OK button to the center? I would like it to display execute program? In that old fashioned type writer font.

Chita79

casper42... is anyone going to pick up where bysin left off? what can be done so that the damn intro nag screen is skipped completely? is it gonna take an assembly guru to reverse engineer it?

crazymjb

I believe it has been done but the poster wouldnt give instructions as it was a copywright violation to post a program that overode that software.

Chita79

ahhh, so somebody did actually bypass the nag screen? just wondering if someone reversed engineered it.. thanks

Chita79

crazymjb: can you please PM me.... i tried PMing u but your inbox is full... i have a questions for ya thanks

All -

I have been a spectator for a while and finally decided to join. Great information on this site so I figured I could give something back.

I went by my dealer today and my sales guy gave me, free of charge, the new v3.50 TL DVD Nav software. I have hacked my nav system and it works great with the new software. I am still playing with the features but nothing really stands out. If anyone knows of any key features that they specific on the 3.50, let me know.

Enjoy

P.S. - I do share - {wink}

acuraTL44

You got the new version?
Somehow you're going to have to show us the difference between the 3.40 and 3.50.

BTW, congradulations on your first post and hope for many more to come

RichChrisB

Well, from what I can tell not a lot of people with Accord are really up on this but I seem to have a problem. I have a 2006 which seems to have the new hardware and I can get to the version screen but when I hold down menu it just goes to something that has 3 pages of lists of different filenames. Has anyone else seen this? And just to make sure I am doing this correctly, I do hold down the three buttons from the screen where I see the roads and a little arrow, correct? Thanks for the help and when I get a chance I will start looking closer at this new hardware.

Chita79

huh? what new hardware? please explain ...

RichChrisB

Well, the 2006 Accords have the newest hardware similar to the 06 TSX. The processor is faster, the background has the brushed look rather than the flat color look, etc . . .

In the root directory of my Navi DVD I have only 5 bin files. 06Touch, 06Touch2, 06Jog, 06Jog2, and VRDB. The Version number is also 1.04.

I'm guessing we'll have to wait for someone with a little more programming experience than myself to analyze the new system. I have a few versions of dumpnavi but none of them seem to cooperate with these new bins.

Just to make sure in DOS I am pointing at the directory which has my 5 bins and the dumpnavi program. I am typing "dumpnavi 06touch2.bin extract". That is correct isn't it? It will start extracting the files ending in 2 but then crashes. The others it states invalid ROM header.

So, the 06 system seems to be completely different and I guess I will try and find some stuff to help me dig into it a little deeper. If anyone would like to see my bin files I will have no problem mailing them. Thanks.

PyroPaul

Would this mean you'd be willing to throw it up on a bitorrent? Would that even work?

Capt_Crunch

How do I find out what version of the NAVI DVD I have? Everyone seems to be talking about version 3.40 and 3.50. I went into setup on my new 05 TL and all I can find is database version 20041119 and software version 1.0010. I have noticed that several streets thate are over 3 years old don't show up all the time.

Chita79

put your key in the ignition, turn it one notch, open your trunk, open the black dvd navigation unit, and hit the open button.... check the actual DVD disc for version info

tzakiel

Is there any step by step guide to editing the text that appears? I'd love to put in "Thank you for driving the Acura TL. This screen is totally unneccesary and even though that is a fact you must still hit the OK button below. Thank you for your time" or something

Maybe some inspirational quotes even... ? lol

tzakiel

What are the dimensions of the bitmap image the navi uses as the startup image? The exact pixel values for height and width I mean. I thought I might do some designs for you all and then post them for free usage for your cars. Any requests?

schrady

U say someone removed the need to press ok? I got rid of the nag screen with my own picture and changed the button to say "ok". but I still have to press it.

I have some sweet DTS albums that play AWESOME in our TL's if you wanna swap some stuff.

I wanna get the new version of our NAV (I have an 05) and get the latest hack!!

schrady

Thats the site address?

dman918

Did you do anything special to make the nag text a pic? I thought this only changed the initial acura load screen pic. The "OK" isn't a big deal, but the text itself is annoying...

MercuryTL

It's football season...

Laxplaya11385

whoa, how'd you do that?

johnny--2k

agreed.....how did you modify the text?

MercuryTL

I'm going to keep it a little general to be safe

Download a free hex editor like xvi32

http://www.chmaas.handshake.de/delph...vi32/xvi32.htm

Extract navi.exe from your bin using the bysin's command line tool

Open navi.exe with your hex editor

Search for a keyword that usually shows up there (*find the second set of words, you wont see a change if you modify the first set* (i.e. press find again))

Type over with your text (spaces and such to center) but you can only change the letters of what's already there (no inserting as this will change the file and don't run over the end of the string). It helps to plan/map it out beforehand. Go slowly.

Put navi.exe back into your bin and you're done.

If you hit any problems with compressed navi.exe being bigger when using bysin's tool to put it back in the bin put spaces over some of the canadian text, this will help it compress more.

P.S. try not to mess up, don't know what would happen if you did, i'm not responsible.

dman918

Is there any way to get a pic there instead of text? Or can the text be changed to a different size, anything?
Thanks!

Staggerwing

It needs to be 480x234, max of 256 colors, 8 bit.

Toronto-TL

Acutally, it's better if you make the color depth 173 colors, the image will load quicker, i've heard people complain about the delay in loading a 256 color image.

Staggerwing

Yeah, I actually had one image that only contained 136 colors, but it still had about a 5 second delay before the picture loaded. I just cut the size down to 477 x 233 and it loaded almost instantly and there wasn't any problem (black areas) where the image was reduced in size.

MercuryTL

This has been working for me with no delay. 475x232, 8bit, 255 colors. With 256 colors I get a delay. I'm sure you could play with the size a little more, but I found dropping from 256 to 255 makes the difference.

jmbnova

Is there anyway a normal guy can do this hack? Or is it possible to get some help with it? How would a common man do this?
