I just managed to remove the warning message from the backup camera display. It isn't necessarily for the faint of heart and I certainly haven't run the unit very long to see if there are side effects.

That being said:

1. I got a copy of AV.EXE from my backup (in the APL folder).

2. Opened it in a HEX editor.

3. At around $290FC0 in the file you will see the warning texts as double-byte (Unicode) characters (every other byte is 0x00).

4. I entered a space to replace each character in the string, being careful to leave the 0x00s as-is.

5. Did they same for the multiple English strings (other languages are there, too).

6. Copied AV.EXE to an SD card with the Testmode stuff.

7. Booted into WinCE and replaced the AV.EXE in the APL folder.

8. Reboot - Test - OK.

Modifying executables can be very dangerous. Be extra careful with this one.

do you mind posting it

Attached. It's originally from an F90BT.

for anyone who wants to try it out here's a modded av.exe for a f90-bt, please make sure you back up your originals,

have you tried digging in the ezrider.exe?

can this be done for the navi messages as well?

can this be done for the navi messages as well?

Won't be nearly as easy... Here, he just blanked out the message. It's still there, just invisible. For the Navi message, you need to bypass the actual call that brings it up, otherwise you'd have to click on a blank screen, because it would still be waiting for the OK button to be pressed...

I just noticed that the warning is still there when the unit is booting. It is NOT there after that. I guess it runs another program during boot that also needs to be modified.

Thank you, thank you, thank you.

I used your zip mod, & it worked for me. I see no side effects - so far. All I can say is, Thanks a lot!

I have a 90BT installed in a Town & Country minivan, 2008, with cmh's mod as well.

Yes, the text at the top of the screen.

I tried it and the reverse image still comes on. Did I miss something? The image is not as dark as before.

Sorry, didn't quite catch that. Do you mean that you can still see the image from the camera or the "CAUTION: IMAGE MAY APPEAR REVERSED" text at the top of the screen?

You'll currently still get the text during boot up. It seems the text is also in another file which is active while the unit is starting up.

Thanks a lot! I just did this and it works perfectly. Much nicer than that stupid message.

There is more of this text in the video EXE file.

What line is this text found? (it's still in the av.exe file?) I searched for it, but couldn't find another spot where it was.

Excellent Work!!!!

Now we can install another video AUX without the need of changing the Av source in the AV Setup...

Thanks. It does go away after it is done booting. Great Job!

Would this modified file would work to remove the message on the F700BT? Has anyone tried it? Should be the same file right??

I have done this on my 700bt and it works perfectly. Just make sure to back up your original av.exe file!

Is there a way for me to do this on a 900bt? I tried copying the av file posted, but no luck.

I keep getting that the av.zip file is corrupt. I've tried on two boxes, opening the zip with winzip and winrar. Just me?

I think the recommended Zip program has been 7zip to avoid these types of problems.
