Nav In-Motion Disable Completed, Patch Available!

[wkearney99]

And if anyone wants my burned AE patch disc let me know.  Otherwise it's just gathering dust.

You'd use this to upgrade a radio that does not yet have the AE disc loaded.  As in, put in this disc, upgrade the firmware, and then put in the normal AE disc.  This one just handles the patching.

If you've already loaded your AE disc then this will NOT work.  You'd have to patch the AE firmware twice, once for the motion disable and the other for the version number.

Possible for a PM with the official or modded AE disc?

Thanks in advance.

I have a suggestion for people wanting to revert to stock firmware. 

Change the firmware version to a higher number than the stock AE disc and make another hack for the code that will always load new firmware, regardless if it's a higher or lower version number than the current firmware.

This of course would mean that you must continue using your burnt disc, unless you somehow can somehow set it to only load the firmware if it's lower than the stock AE disc and the current version number.

Been looking to bypass the version check for a while. Having units running in the garage here and updating them constantly sucks without being able to go backwards.

Been looking to bypass the version check for a while. Having units running in the garage here and updating them constantly sucks without being able to go backwards.

Using the MAIN.APN from version AE, the following change should make it so that the unit will load any disc version that's different than what is currently loaded.  So anything higher or lower, but not the same.

Care should be taken with this, because if you stick in an AB, AC or AD disc it will attempt to load the old version of the software and may kill the unit.  From what I can tell the unit has to have compatible versions of the MAIN.APN and APL.APN files running, and using this hack will cause it to load an old MAIN but I don't think it will effect the APL.  So again, applying this edit and then sticking a non-AE version of the disc in may kill the unit.

But for the brave, we want to change this:

Code:

784ab1c: 0e 86   bnh   784ab2a <_DvMt_CheckForUpdateVersion+0x6a>

to this:

Code:

784ab1c: 0e 86   be   784ab2a <_DvMt_CheckForUpdateVersion+0x6a>

which requires changing the "86" to "84" at location 1A:DBFCh in the MAIN.APN file.

As always, need up update the checksums after that.  And I always like to disassemble the patched code and make sure it really did what I expected it to do.

Of course, one problem with this is if you're using single layer discs for doing the updating, once you insert your DL disc with the database it's going to re-load that version again.

I suppose you could use this once to revert back to 2.04 and then go back to micro increments using SL discs.

I would sure like to get a handle on this with the unknown future of updates yet to be released.
Any brave souls ready to step up??.. ')

I am so excited.. I have a dodge 2006 3500 Ram truck... I hate the in motion menu.. My truck was purchased in may 06.. I am guessing I have the AD disc.. I will have to look tonight..

I saw links for torrents.. but they didn't seem to be active any longer..  Should I be looking for another torrent? get my hands on a OEM AE disc  and patch it? or? 

I am really looking forward to trying this in my truck..

thanks

Ok guys. I had an old version of the disc. (AB) Anyway I made a backup of my AE disc with the patched files. When I first put it in it said error reading dvd-rom check disc. So I made sure there were no fingerprints or anything on it and reinserted it. This time it started to work and powered off and went into the software/firmware update screen. It loaded that all the way and then restarted. Went to the loading screen, but it never gets to the point where it lets you hit enter. It just keeps coming up with the unable to read dvd-rom error, but everything else seems to be working. I'm assuming my update went fine, but it is having issues reading the maps on my burnt disc. Can anyone help me out here? I used HP DVD+R DL Write speed was as slow as it would let me. Used burn4free software. Thanks and any help would be appreciated.

Have you completely verified the contents on the copy of AE that you made? It sounds like a couple of the botched discs we had where the unit would update, but for operation we'd have to put the stock AE back in. If you have a good copy of the original AE, put that in and it should work fine. There's nothing on the disc with the hack that you need at this point.

Thanks everything is working fine now using the AE.

No problem, good to hear.

Always like those happy endings..

Ok still having on and off problems. It worked for a couple of days, but as soon as I tried to route to a street intersection it said it couldn't read the dvd-rom and then would hang on the loading screen. Didn't make a difference how much I took it out and re-inserted. Parked the car for 3-4 hours and it then worked including a route to an address. I guess I need to try another disc. What disc does everyone recommend?

[pirate4x4lance]

hey titan, did you try to make a "program only" disc now? does it work with a single layer disc sans map data?

I am scared to until I get some assurance that it will work   I really just want to know which large files I can cut off to make it fit on a 4.7GB without posing a problem before I dive in.

Has anyone tried this yet? I would just like to use a single layer dvd (since I have a ton of them) to load the hack and then just use my factory AE disk for normal use.

[pirate4x4lance]

Allright guys, I just thought I'd let everyone know that I went for it on my 2 day old Ram.... 

I used a single layer Sony DVD on my Apple powerbook, and used the included burn utility. I put everything on the DVD but the massive map files. It worked perfectly first try. I will use my OEM DVD for the maps.

Macs rule!
