My source of information was system interconnect diagram from TL service manual. According to it, Navi has a mono audio output, which is connected to the audio headunit. Quite possible that audio chip inside the navi can output stereo, but to get the second channel in the audio system will require hardware modifications too complicated for vast majority of people. On the other side, some people will be happy with mono sound. I myself could live with it when listening to audiobooks.
I just hope you will be able to brake the software. I know that this is far from trivial, so I just keep my fingers crossed.

do a check of the system by holding down the 3 buttons , go to version and hit menu.

Note the file its loading , its probably currently the honda file that you used . Not the bnhh401a file

your car thinks its a honda
so on your MOD disc if you did a one to one swap of the honda and acura file. by USING THE MOD DISC not the original disc, loading it it will load the honda file, which is really the acura.
now it thinks an acura and will look for the proper bnhh401a file

then you can but the original dvd back.

you didnt read my prior post carefully

it's very strange

it says it loading bnhh401a, but the other file it's loading is not on the cd it's says program filename is 03MY-UA-US

here are some pics of what i have

got it working again, very simple to switch back and forth(i suck at reading)

I`ve taken BN2HH12C.BIN (2004 Acura TL) and renamed it BN2HN18B.BIN (2004 Acura TSX), then vice-versa, renamed BN2HN18B.BIN (2004 Acura TSX) to BN2HH12C.BIN (2004 Acura TL)... then used the DUMPNAVI program to change the backround.bmp of the NEW, BN2HH12C.BIN (actually the TSX.BIN)...

Everything took great, just like I was only changing the startup backround image, still ACURA, only now I have the TRIP COMPUTER... I was hoping that since I changed over to the TSX.BIN, the DUMPNAVI would allow me to modify the nag screen, but no such luck... I guess i`ll take what I can get...

I've been following this thread like it was a 1950s potboiler. :thumbsup: Its got all the thrills and drama of a best seller.

At some point will one of you l33t h@x0rs outline the process for us poor old n00bs? What you're doing is truly remarkable and I'd love to do it too but haven't a clue where or how to start.

I'm sure there are other lurkers who share my hope and would be greatly appreciative of the guidance.

TIA

:clap:

I think you got it now. If you simply invert the two files your file for the one you are subsitituting for. You can use the MOD disk to go back and forth between the two mods.

each time it looks to the opposing file for instructions

bnhh401a.bin <---> bnhn404a.bin

reloading each time switches it back and forth, ( WITH YOUR MODDED DISK INSIDE ONLY)

yup i got it, took me a little time

how did u guys get the Trip Computer?

...

I'm begging you, please do a write up. I would love to do this. Please do a write up!!!!

i 2nd that! please please please

3rd that. I guess I just want to have any and everything I can within this navi screen.

Someone please do a how to

Just been reading this thread.... the anxiety is killing me. No one here can post a how to?

Thanks!
 

Thanks a lot for the step-by-step guide.

If I needed to restore back to "factory settings" would I just reload the TL file or does the battery need to be disconnected so the system will cold boot?

Do you lose any features by using the TSX's BIN instead of the TL's BIN? I see you gain the trip computer and climate control status display, but is anything lost? You would think that there are some things in the TL's BIN that aren't in the TSX's right?

Are there any drawbacks to this? Does everything else work as it should and whatnot?

Per my understanding of this, we cannot have a customized backgroud screen as well as the climate control and trip computer screen in this whole package. Its one or the other - right ?

You should be able to do it all. Theoretically you are just using the TSX's BIN file. You can customize that file the same as the TSX owners do. Am I right?

When http://=https://acurazine.com/forums...d.php?t=112576 happened to me, I lost the Subwoofer and Center audio adjustments that you see when you press the on-screen [SOUND] button and some of the voice functions didn't work either, I don't recall which ones. Additionally, the clock on the display above the Nav screen wouldn't adjust itself for daylight savings time either despite the clock you see when you enter Nav diagnostics showing the correct time. In other words, I had theeee Honda Accord Nav system in my TL. The dealer wound up reloading the original TL system.

If this adds the trip computer WITHOUT messing anything else up whatsoever, I'll definitely do it!
Please advise ASAP tizo !!!

Thanks for the write up, Can you tell us what is lost by doing this?

Yeah, I wouldn't want to lose anything. Someone with this installed please let us know what this takes away, if anything.

Somebody's going to figure out how we can mix and match features from the different BINs. It's only a matter of time (hopefully). I, personally, would not want to lose either sound adjustments. I'm very picky about sound quality, and am constantly adjusting the Subwoofer adjustment on different CDs, radio stations, etc. Not so much the center channel, though. Never adjusted it much before, but now that I put in my aftermarket amp/subs it's a must.

just a little fyi.

When you change the bin file and end up with the trip computer. You lose some of the voice commands. Im not exactly sure but some are diffrent. As far as loosing your ability to choose the sub woofer and center speeker you cant do this from the nav screen. You still can change it by pushing the right silver wheel. and using the upper display to do your adjustments.

Im curious did the TL navi have the 1/2 grey dotted bar at the bottom and give you the road names all the time. I have the bar now and dont remember it being there before.

I wasnt to impressed with the trip computer Im probably going to switch back to the tl disc.

Yes, that transparent grayish bar on the bottom of the screen that shows the street names has always been there.

thanks. I just reverted back to the acura version and noticed it. Also there are some A/C commands that are diffrent. as well as dvd disc commands.

Question About The Trip Computer...
 

how does the trip computer calculate instantaneous MPG???

My question is does the Trip Computer think that the car IM driving is a TSX? (I have the trip cpu in the TL now). Like when i floor it does it think im flooring an inline 4 or 6 cylinder engine.

I'm sure the trip computer doesn't compute MPG based upon how you drive the car. I would assume it calculates the gallons of gas used per driven mile. The only problem could be if the tank in the TL is a different size than that of the TSX, in which case it may think it's using more or less than it really is.

the only thing i find on mine is that the climate control display doesn't work right, except for the temp numbers everytime i push a boutton the naiv screen says climate control off eventhough it's atually on

Don't give up guys!!! Hopefuly someone comes with a solution for all!!! I'll keep my fingures crossed.

hit the auto button and see what it says then. Mine said off untill i hit the auto button.

I dont know how accurate the instanatious meter is. The other info is right on with the MID. The instantanious when I was cruising on the highway said i was getting 35-45mpg. but the actual number on the MID was about 32 but its something neat to distract you and make you crash.

haha those were my thoughts exactly when i was driving and looking at the Instant MPG... i would step on it and watch the MPG drop and if you just coast the MPG goes up to 50. still pretty neat tho... althought i dont think its very accurate because it stayed like 30mpg+ the entire drive and it still only said like 20 mpg on the mid. :(

The climate control looks like it's blocking your compass. Does it go away like the audio display does after awhile? OR does it stay up?

it goes away just like the audio does
