Re: UConnect 8.4 International / Export

Just some knowledge... from what I have done a bit of research on.

The Jeep models and their maps (Australia based Export GC) I have found:
JGC MY14 Laredo - Maps default are 2012Q2 Dated 20121211
JGC MY14 Limited+ - Maps have update to 2012Q2 Dated 20140418
JGC MY15 Laredo - Maps default are 2013Q4 Dated 20140716
JGC MY15 Limited+ - Maps have update to 2013Q4 Dated 20150310
JGC MY16 Laredo - Maps I assume 2014Q4 Dated 20141116
JGC MY16 Limited+ - Maps have updated to 2014Q4 Dated 20141116

I can only assume this is because FCA need to pay for each and every Jeep they have that is activated with maps out of the factory.. which is stupid, if you are paying for the vehicle, I'm sure they could include the costs of the latest maps in the vehicle price!

As for 3D Maps, these are not present on a Laredo model (claim is that there is not enough disk space since they have a 8gb Flash memory instead of 16gb). Limited have the 3D maps etc because they have more disk space.

There is actually only a License limitation factor for the Map Files themselves, and NO they are NOT specially built map files for the Jeep, they are the standard HERE map files (to be technical they are the same ones iGO devices use)... and to prove this I have enabled/installed 2015 Q3 maps (with 3D buildings/landscapes, my uConnect had 4gb free space and 3d map files arent big at all for Australia only, rest of world are large!) in my 2014 MY14 Jeep GC Laredo.

The only problem is I had to circumvent the uConnect and upload my own map files that I obtained, along with a valid license file (purchased from iGO Navigation on my Android phone), and a few "hacks" to get navigation going... It's not for those who have no technical background.. and even I needed some assistance from more experienced members of this forum to get it to work.

Re: UConnect 8.4 International / Export

This is good stuff... at least comforting to know that all is not lost if Cheap Australia abandon us as I expect they will/have.

How much would you charge to update a unit sent to you? 😉

Cheers,
Steve

Re: UConnect 8.4 International / Export

I would still like to have the maps in my unconnect, and am going to the jeep dealer near me to see what Jeeps story is on the updates etc

Re: UConnect 8.4 International / Export

Leighm0 Is there any way that you can share how you add the updated maps to the unit?

I have iGo navigation with latest maps for Middle East (same RJ4 unit) that I could use to extract the maps from it to update the Uconnect.

Thanks

Hi,

You need a few things, and technical knowledge is a must:
1. A patched "NaviServer" executable done with IDA Pro to accept licenses from other iGO devices.
2. The latest Update ISO you currently have running on your car.
3. A Patched Update ISO File modified/setup to run a custom LUA script instead of the upgrades. (I used the 14.25.5 RA3 disk, because it is small). Another thread on this site explains how to patch it.
4. Copy of the iGO Navigation Map files and most importantly a working iGO Navigation License file (.LYC) for those maps. Only take a copy of the building, dem, map, phoneme, poi and speedcam folders. DON'T include any vr, skins, car, global_cfg or other folders in the "content" folder.

Method of attack:
1. Patch an update ISO to run only your custom LUA script and then reboot, this info can be found on this forum.. I get mine to mount the filesystem as read/write and then run custom.lua from the USB stick.
2. Using this custom.lua script you should firstly do a bit of copying of files from your uConnect. You need to grab a copy of /bin/NaviServer file to patch it, best to try copy this off while the uConnect is running in Normal Mode not Update Mode so you will need to patch "/fs/mmc0/app/bin/nav.sh" (or boot.sh if it is there still, newer firmware moved this file to /bin instead which is read-only) to run another LUA script from USB on Normal Boot to copy this file off the uConnect to your USB stick (or alternatively hack SSH to run and copy it out that way over Wifi/ethernet USB dongle using WinSCP).
3. Patch the copied off NaviServer to accept licenses from other devices using IDA Pro - I believe the function you look for has some plain text about "license is not valid for this device", you need to modify the check and accept any license for any device. Rename the patched version to NaviServer2 for example and copy it to your USB stick root directory.
4. Open up your current Update ISO that is the version used in your vehicle and copy off the "nav.sh" and "navRestart.sh" files from the "\usr\share\MMC_IFS_EXTENSION\bin" directory to your computer.
5. Modify these two files in Notepad to run your NaviServer2 instead of NaviServer... Just find where it says NaviServer and just change it to say NaviServer2 in each location. Copy these files to your USB stick root directory.
6. Copy your iGO Navigation Maps and Licenses and put them in their respective directories on your USB stick and put the LYC license files on the USB root directory. The iGO Navigation files should be in sub-directories like they are in your iGO MicroSD Card (under "content" folder).
7. Now create a new "custom.lua" LUA script to run during the modified update ISO to copy from your USB root directory the "nav.sh" "navRestart.sh" and "NaviServer2" files to "/fs/mmc0/app/bin" location on the uConnect. You will also need this script to copy your iGO Navigation "content" folder to "/fs/mmc0/nav/NNG/content" location. The License LYC files need to be copied from your USB root directory to "/fs/mmc0/nav/NNG/license/" location on the uConnect.
8. Now on your custom made USB stick you should have all the files:
- Your patched Update ISO (swdl.iso) file to run custom scripts during upgrade mode and reboot.
- Your patched nav.sh, navRestart.sh and NaviServer2 files.
- Your iGO Navigation "content" folder and your .LYC file(s).
- Your custom.lua script configured to copy files during upgrade to the right locations.
9. Double-check you have all files on the USB stick and your custom LUA script is setup to copy these files to their correct locations on the uConnect.
10. Run the update USB stick in your car.
11. Reboot and check it has now got your new maps running - best way to check is look for 3d building objects, fixed speedcams which were not shown in your old maps, POIs, and any roads which may be missing which could/should be in the latest maps you uploaded.

Nah it's surprisingly forgiving, I did F up a few things myself when I was doing some other hacks (SRT unlocks and stuff) and managed to cause the Touchscreen to not show any interface.... luckily I had already gained remote access, and a boot script would run custom code on startup - was able to revert changes.

I'm glad I still have the warranty if it goes down I'll just take it to the service and let them replace

Haha.. and good luck explaining to them that you were "hacking" your vehicle to try and update the maps manually using patches and circumvention.

They probably have no clue how to fix them in these types of situations..
