Sorry, I should have included this link for you to read more on the GVN53 (http://www dot gpscentral dor ca/products/garmin/gvn53.htm) . Just so everyone knows I have nothing to do with nor am I associated with Garmin. I simply use several of their GPS units and find they work well - which is all I ask of a GPS unit.

Id' like to help out with some of this code search. I consider myself somewhat savvy when it comes to figuring things out. I'm a Java programmer foremostly so I'm not intimately familiar with HEX searching and bin decompilers.

If anything, I do have a 4.62 silver Canadian DVD that I got with my 08 TL-S if anyone needs me to try anything out with it.

Does any one successful on disc 4.56?

Found this in another thread. Don't know if it means anything or not, but thought I'd post it for you developer/programmer types just in case.

I think Bysin was talking about the 3.x hacks.

Anyway, I'm exahausted and heading to bed, but if anyone wants to continue, I found the Nag Screen text in the file - hmimanager.dll. It starts around offset 000A8D00. There is a bunch of other text too, so I'm sure something is calling this file for the screen, just haven't figured out what yet.

Although much that is posted here is already known / published elsewhere, it's good to have it all in once place. Typically there is text listed there, but it's just a string. One needs to find where this data is read into or used to be displayed. That should get you close to where the logic is looking for a keypress.

It would be helpful to know what is called in the OS to get screen coordinates, or if it's making a call to a known "click ok" dialogue box in the OS. We would just change the call to a NOP instruction, or a return or JMP as appropriate.

In post #711 I asked if anyone had disconnected their DVD drive unit in the trunk to see what effect it had on the rest of the features. I had been led to believe that everything else would work . . . well it turns out that if you disconnect the DVD unit the entire Navi screen goes black and stays black until the drive is hooked up again. So much for that idea.
Here's a to the Acura Techline guy that passed on this little tidbit.

You found the strings table most likely; you need to find who is loading that string from that address. I assume this would be a load instruction in the assembly. Use IDA Pro Disassembler to pull apart things and see if you can figure it out from there. I believe the unit uses the SH4.

Anyone from Europe on these boards? Do they even sell similar Acura's in Europe? If you're out there, PM please.

Binx57

Honda does not sell - nor do they plan to sell the Acura brand in Europe.

If I have to press that OK button on more time, I'll go gladiator on it, unleash on it with a hammer, sob.

Any solution for the OK hack for the new version?!?! I can't take this OK nonsense no more, no it is not OK! freaken my own car harasses me every time I start it.

Binx57

Even if we get this idiot button bypassed the minute you update your CD - you will have to start all over again. If you want a permanent solution go here - it is a hardware solution - most expensive model is $50. To date it is the only solution.

TeknoKing

Binx thanks! but I don't think I'll be upgrading the dvd. In regards to buying a hardware solution, 50 bux just to press an OK button is not a fix, that's simply a macro.

Is there a specific file I have hex to falsify the OK button input?

My main question is this, if I take the Navi DVD, and I image it, and reburn it on a DVD-R, our TLs will still recognize it??? Thanks.

Binx57

To gain some perspective on the OK button, I would suggest you go back a couple of pages in this form - 2-3 will do. Then you will know about as much as the rest of us do on a Hex edit.

I have copied the DVD onto a dual layer DVD-R but it wouldn't run. It seems that, at least on my 4.55 there is some type of copy protection that isn't copied onto the new DVD.

I have not tried imaging the disk though. Give it a try and let us know what happens.

TeknoKing

Binx57 sounds, good, I will give it a try... I just need to purchase some dual layer dvds.

I think I can image it... Thanks for the info!

onyx1121

Ok, first off, a hex editor is not going to be very helpful in hacking the OK button. You need to start with a disassembler that works for the Navi. processor (SH4 I believe). All you will find with the hex editor is the strings table, and change that won't do anything. So stop wasting your time.

Second, the 4.55 DVD can be copied - I've done it. Just image it. May take a couple burns depending on your burner.

TeknoKing

Yes, it can be copied, I imaged it, and it worked fine.

onyx1121, do you know which disassembler for sure? damn, I haven't touched this stuff in years, I guess it's time to remember my college days of machine language, lol.

pg_rider

Someone should put up a "reward" for the first person to crack the "OK" nag -- gotta get these smart guys motivated! Kinda like the X Prize...

(willing to donate $10 to the cause...)

blipszyc

pg_rider - great idea - I'll throw in $10.

Lenny11

TeknoKing, Was there anything special you had to do to make the working copy of the DVD from the ISO image? Can a copy be made with any ISO image copier such as DVD Decrypter onto a dual layer DVD? I was under the impression that you needed a manufacturing DVD burner to recreate a working copy. I am interested in having a backup copy of my current disc to fall back on, as I'm sure a lot of people in this forum are too. Please let us know. Thanks.

TeknoKing

I just used MagicIso, DVD43 running in the background, I imaged it, and burnt it on the dual layer, I can't remember whether it was DVD+R or DVD-R... I believe I've used DVD+R.

I do have a plextor dvd burner, where it automatically sets the bits as the original dvd, so it depends on multiple things, but it should work.

rookie1011

I'll drop $10 as well

Binx57

Ida Pro works fine. There may be others, but I have not tried them.

wgambella

I offer $100.00 to the brave soul that can kill my OK nag button, and change my welcome screen on an 08 TL with 4.62 navi disc. I am in North GA if any brave soul can pull it off.

blipszyc

Changing the welcome screen is easy, and there is a device to "click" the button for you for only $50. Sooo, I'll stop by next time i'm in the area and make a quick $50!

onyx1121

Just get IDA Pro and make sure whatever version you get has support for the SH4.

As far as those talking about the "click" solution. Sure, it may work, but its what I would call a kludge; disabling it in software should not be too hard. It's just a matter of being familiar with things and being able to dedicate the time

P.R.E.A.M.

ok can someone help me
I am hung up at one point in doing the splash screen on my 4.62 white disc

when i get to this point i get this

any help would be great
BTW I'm using pics from this site and making sure they are in 256 bmp format

Unit-X

I am interested in trying out this hack. My question is, no matter how bad i screw up, I can always do the above instructions and it will go back to its original state regardless or what happens??

blipszyc

You need to make sure the BMP you want to convert to 16-bit is exactly 113,398. I've found that Irfanview does the trick. I think its a free program. (google is your friend)

P.R.E.A.M.

Thank you very much got it all done now and uploaded into the car
now only if the "OK" will disappear

Anthracite226

Hey i have the 3.330D orange disc and when i use the dumpnavi program i get a INVALID XIP FILE error

Everything is in the same folder i just cant extract the BIN file

Any thoughts??

dumamei

Can the welcome screen be changed on a 08 TL? 4.62 disc

If so, do i follow the instructions for the 4.55 or is there a set of instructions specifically for the 4.62 disc..
I havent seen any instructions specifically for the 4.60.. If there are instructions for the 4.62, can someone please specify the exact page and thread, so I do not have to search through 700,000 pages of content..


thanks for your input in advance..

blipszyc

Yes, the same instructions for 4.55 will work on 4.62. Just did it the other day. If you're having problem, be sure the file sizes are EXACTLY the same size.

P.R.E.A.M.

same here . I just did mine last night

Igor911

I wish someone would figure out that OK button already

blipszyc

Working on it - sit tight.

You guys are awesome!! I almost feel bad reaping the benefits of your research. Thanks!!!

I so agree. with out the great guys on here i would be so S.O.L.

If you are new to this thread, like me, it seems the original hacks have evolved and it's not quite clear what does what anymore.

The original, by bysin, appears to do 3 things:

- Change the background image.
- Removes the "nag screen" at startup.
- "Change some of the words that pop up".

Questions:

1. What words?
2. If bysin's hack removes the nag screen, why do we need AngryDad's "OK" hack?
3. What's the point of people uploading images if they are not formatted to the required system specs?

blipszyc

I know the first post isn't that confusing, but here's a recap:

Bysin's program allows you to extract and then reinject files into the 3.x BIN files. This allows you to change the background image, enable hidden apps like Trip Computer and A/C Controls, and remove the nag screen with AngryDad's OK hack. (or the others that remove the "AD" text) Bysin's program is not the hacks themselves, just the enabler. As far as the words, I think its the nag screen words. AngryDad's hack doesn't get rid of the text, just the need to tap the OK button. If you want to change the text, you can.

For 4.x BIN files, bysin's program will allow you to change the background only. For now.

In regard to backgrounds, there is a nice thread with bmps and directons on how to make your own that meet specs. Most of the pics uploaded meet the 3.x specs, but not the 4.x specs. You'll need to either save the pic as a 16-bit bmp, or get 8to16.exe to convert the 8-bit bmps.

Good Luck!
