Hey everyone, been lurking around for a while but finally got to an error that i can’t quite figure out.

some background; doing this on a 2014 Dodge Journey SXT w Uconnect 8.4N - CTP13 v4.08.

I followed the original post’s instructions - to the letter - and i can’t get past the damn validation error. i have two other usb sticks lying around, however can’t use em with the car because it returns a “USB Read Error” and the player tab says “please remove from system”. I’ve tried going the route of using the diagnostic file manager to delete the file (nav -> settings -> system -> about, then holding just above the “more” button for ~8 seconds) but i get an error saying it can’t delete the file. going to test mode -> inventory, it says both Gsuppmap and Gsuppmap1 are deleted, however going back to the file manager gmapprom.img is still there, taking up about 1.92GB. i’ve never heard or seen this before.

Any advice? i’ll pick up another USB stick soon, however i just would like to know if there’s some other things i can do to the car’s computer before i cave.

Any advice helps!

Thank you in advance 🙂

Question;

The map package is getting large and the 3590 navigator files I use still take the full update. If I stick the image on a smaller key I get a message saying there isn't enough room, but Garmin Express doesn't offer to use a smaller subset of the map, which, strangely it does on several other navigators that have limited memory, use the same gmap files and such, but don't have the same various support (ASR and SID) files.

The question itself is whether I can use the smaller gmapprom.bin file and the gmap3d.bin from a 3790 (which has no ASR files and the SID, and other files are different) along with the various support (JCV/ASR/SID) files from a 3590, so that I would have a smaller map package which would provide more than enough coverage than I really need?

If anyone knows I certainly would like to hear, since it takes way too long to update the navigator to try random files only to see them fail.

Thanks in advance.

This has been updated with the 2015.30 file names!

NOTE: I wanted to thank user "tanbam" for these instructions, and for his permission to use them to start this thread!

This map updating process is for the CTP13 and newer radios on the following vehicles:


Chrysler 300 2013-2014
Dodge Charger 2013-2014
Dodge Dart 2013-2016
Dodge Journey 2013-2017

You should see an arrow for "Where To" when going to your navigation screen:



If you have a 2011 – 2012 Charger, the files needed are different and instructions are located here:

HOW TO: Map Update on Uconnect CTP11 & CTP12 (2011 - 2012)

----------------------------------------------------------------------

Getting Started - What you will need:

(1) Compatible Garmin Nuvi which has 3D maps and junction views.
(2) Compatible USB flash drive at least 8GB in size
(3) CTP13 firmware if your unit doesn't have it!
(4) Garmin Express to update the maps on your Garmin Nuvi

----------------------------------------------------------------------

Step 1: Getting update files from the Nuvi


Begin by plugging your Nuvi into the computer and running GARMIN Express or Garmin Map Updater. The program will let you update your Nuvi software and will install the latest map update. This will take some time, so just let it do its thing.

After the Nuvi has been updated and has the latest maps, you must enable the Mass Storage feature so that you can browse the files using your computer's file explorer. After this is done, your Nuvi will show up in your computer like a normal USB flash drive. This only needs to be done once.

To enable Mass Storage in the Nuvi:
1) Disconnect the Nuvi from the computer.
2) From the main, "Where To?" screen, tap the "Volume" button.
3) Tap and hold the upper-right corner for about 10 seconds to enter the Diagnostics Page.
4) Scroll down and tap "MTP Settings".
5) Select "Mass Storage" and tap the "Save" button.
5) Tap the back arrow button twice to go back to the main screen.

After Mass Storage is enabled, plug the Nuvi back into the computer. To copy the update files to a USB stick:

1) Ensure that the computer is set to "Show hidden files, folders, and drives", and that "Hide extensions for known file types" & "Hide protected operating system files" are both unchecked. This will allow you to easily find the Nuvi files and avoid confusion.

2) Plug a blank USB stick into your computer and create a folder named "Garmin". All of the update files will go into this folder, regardless of where they came from in the Nuvi. Inside the Garmin folder, create three more folders named "ASR", "JCV", and "SID".

3) Open the Nuvi 'drive' and browse to the ".System" folder which should be visible at the top of the list. If you don't see it, go back and double-check that step 1) was completed properly.

4) Copy ONLY the following five files from the ".System" folder in the Nuvi into the "Garmin" folder in the USB stick (UPDATED FILES IN GREEN):

gmap3d.img (07/01/2021)
gmapprom.img (07/01/2021)
gmapbmap.img (03/14/2011)
gmaptz.img (05/03/2021)
gmapdem.img (07/01/2021)

5) Browse to the ".System\ASR" folder in the Nuvi and copy ONLY the following four files into the "Garmin\ASR" folder on the USB stick:

06U3MARK.SRX (07/01/2021)
06U3MARL.ASR (07/01/2021)
06U3MARM.ASR (07/01/2021)
06U3MARN.ASR (07/01/2021)
*Note that these file names are ONLY for 2022.20 map.

6) Browse to the ".System\JCV" folder in the Nuvi and copy ONLY the following file into the "Garmin\JCV" folder on the USB stick:

D31913780A.JCV (07/01/2021)
Large JCV File D3060350A.JCV
*Note that this file name is ONLY for the 2022.20 map
**Note that there are three different versions of the JCV file, determined by size! The above listed is the MEDIUM sized one!
.

7) Browse to the ".System\SID" folder in the Nuvi and copy ONLY the following two files into the "Garmin\SID" folder on the USB stick:

D2656400A.SID (07/01/2021)
D3406360A.SID (07/01/2021)
*Note that these file names are ONLY for 2022.20 map.

When you are finished, the folder/file structure on the USB stick should look like this:

└───Garmin
. │ gmap3d.img
. │ gmapprom.img
. │ gmaptz.img
. │ gmapbmap.img
. │ gmapdem.img
. │
. ├───ASR
. │ 06U3MARK.SRX
. │ 06U3MARL.ASR
. │ 06U3MARM.ASR
. │ 06U3MARN.ASR
. │
. ├───JCV
. │ D3191380A.JCV
. │
. └───SID
. D2656400A.SID
. D3406360A.SID

Some folks may notice that this does not include the full set of update files that come with a Nuvi update, however, these are the only files that are required for the CTP13 and newer system. The other files will just be taking up unnecessary space.

----------------------------------------------------------------------

Step 2: Unlocking the gmapprom.img and gmap3d.img files

Now that the update package is on the USB stick, there is still one more step before it can be uploaded to the car. This may be unnecessary, but it's better to be safe than sorry.

The CTP13+ systems do not require you to generate an unlock code, but two files, gmapprom.img & gmap3d.img should be manually unlocked before they go into the car.

The best program that I've used to unlock the maps can be found here:

Garmin Image Tools

Download this file to your computer and unzip into a folder on your desktop.

To unlock the two files, simply drag-and-drop them one at a time onto the "gimgunlock.exe" file using your file explorer. It will only take a couple of seconds to unlock both files. A command window will flash by, so fast you may miss it if you blink.

----------------------------------------------------------------------

Step 3: Updating the CTP13 and newer map in the car

Now the update package is ready to go into the car.

It could very well be that the update is ready to go as it is, but I didn't use this exact method while I was getting my system going. I was trying to use the full nuvi update package, which I believe may have been too large. This smaller file set may install fine with no problems.

I'll post the method that I used after this post, but hopefully it won't be needed since it requires you to go through the update process multiple times.

1) Toggle the Start button to the ACC or RUN positions. The car engine needs not be running, but be aware that the car will turn itself off in the ACC or RUN positions after a period of time. It is critical that you don't allow the car to turn off after the update process begins. Either babysit it by periodically cycling the Start button to reset the timer (make sure the doors are closed when doing this) or just go for a drive while the map is being updated. The update can take more than an hour, so plan accordingly.

2) Go to the navigation screen and plug the update USB stick into the USB jack in the center console. The radio will recognize that an update disk has been inserted, and will begin validating the files on the USB stick. This may take some time.

If the validation process has an error, especially if a "0x31A0" pops up, then this all-at-once method will not work. Please go to the next post for further instructions.

If the validation process passes, a window will pop up and will ask you if you want to update to the newer map. Proceed through the onscreen prompts.

3) After this, the radio will reboot and begin copying the new files into the system. This will take a long time, so just let it finish.

Occasionally, the radio may lock up at the reboot stage. If it doesn't reboot after a minute or so, you must pull the radio fuse in the trunk. I have no idea why this happens, but nothing bad happens to the radio and you can simply repeat from step 1 again after plugging the fuse back in.

4) After the install process has reached 100%, the radio will again reboot. It may either tell you that the map update was successful or not, but if it got all the way to the end, the update was successful regardless of what it says.

5) Go into your settings and verify that the maps were updated to the latest version.

6) Enjoy!

----------------------------------------------------------------------

Step 4: Fallback method for installing full update


This is the way that I updated my maps. It's more painful than the way I posted earlier, so I hope the previous method is good enough. I've spent so much time going through map updates that I just don't have the motivation to go back and do it again! Hopefully someone will chime in soon with a success story.

The problem is that the maps are getting too big. If there's not enough free space in the radio to fit the updated files, the validation process will fail.

There is a way to 'clean' out the radio of the older map files so that enough space is recovered for a full update.

Unfortunately, there's no way for us to plug a computer into the radio and make any changes, so we have to use the UConnect method.

When you install the new map, the old files are deleted during the process. If you do not have new files to replace them in the update USB stick, nothing gets copied in their place so the internal flash drive space is released.

I used a three-step process, but maybe steps 2 and 3 can be combined into one single step.

Step 1:

1) On the USB stick, create another folder in the root named "Disabled".
2) Move all of the Garmin subfolders (ASR, JCV, & SID) into the "Disabled" folder.
3) Plug the USB stick into the car and perform the update. It will be faster, since fewer files are installed.

When this is done, you will have only updated the three files in the Garmin folder, gmapprom.img, gmap3d.img, and gmaptz.img. This will give you updated detailed maps, 3D landmarks, and time zones.

Step 2:

1) On the USB stick, move gmap3d.img & gmaptz.img from the Garmin folder into the Disabled folder. Leave gmapprom.img in the Garmin folder, otherwise you will get a "NO FILES FOUND" error
2) Move the JCV folder from the Disabled folder into the Garmin folder.
3) Plug the USB stick into the car and perform the update again.

When this is done, the Junction View is now installed, and the 3D landmarks and time zones are still there.

Step 3:

1) On the USB stick, move the ASR & SID folders from the Disabled folder into the Garmin folder. Leave gmapprom.img and the JCV folder in the Garmin folder.
2) Plug the USB stick into the car and perform the update once again.

After this is completed, the system is fully updated to the new maps and all features work except for the phone number lookup.

As I mentioned, steps 2 & 3 may possibly be done in one step after cleaning out the old files in step 1.
Can you tell me if a Nuvi 760 or 765 is a compatiable?

Happy New Year. For some reason, only my nav portion of uConnect keeps rebooting. Basically, the Garmin is rebooting every couple of miles and if I'm navigating, it will continue where it left off. In addition, I've noticed that the search for preloaded locations (gas stations, grocery, etc) has become extremely slow. I'm assuming they are related in some way. I am just going to reload all of the 2022.20 map information, to see if that sorts it out. However, I have noticed that Garmin Express is offering my Nuvi 3590 a map upgrade to 2022.25. Has anyone tried this latest version of the map? I'm using CTP13 4.08 in my 2017 Journey successfully updating maps for the last 3 years that I've owned the car.

Does anyone by any chance have the map3d.img and gmapbmap.img files for the 2023.10 update? I have all the other files needed just missing those two, hoping someone here could help thanks

update

Used the gmap3d from the 2022.20 update, worked fine. Used fallback method for update, though the system automatically took the files out of the disabled folder and updated it all in one go?

Hi All,
Can someone send me the CTP13 firmware. I asked for google drive access but did not get it yet.
I swapped my original non-gps unit with an e-bay RB5 one with it, now took the car with me to europe from middle east and need EU maps to try.

Thanks got it.
In my case I was looking for an old map, 2013, 2014, its the only way to get an EU map to a US device ( in my case its from Maserati Ghibli ). I successfully downgraded to CTP13, now trying to join a 2013 map with the 2022 EU map.

OK so here is how they resolve the navi loading failure and CTP upgrade/downgrade error:

As said above, key is to delete the big size Gmapsupp.img.

Before doing this, you have to make sure your USB is Ok to the system (it is not as picky as upgrading maps), preferrably USB 3.0 FAT32. Size might be not important here as GCD file is not big as map. Also, since I got all CTP files from Chinese forum, the navi language might be Chinese in short term but the interface and button locations are the same and keep in mind the purpose is to delete Gmapsupp.img to free some space, then in theory you could flash any other English navi CTP file.


Prep:

USB 1: download gupdate.ctp13.hack from here: MEGA and write it to USB1\Garmin folder
USB 2: download CTP 13 3.15 main program here: MEGA and write it to USB2\Garmin folder

1. Enter Dealer Mode -- GarminRecovery Update -- inssert USB 1, start garmin recovery update.

2. Once update is completed, system will reboot. It might take some minutes to reboot and load, be patient. If it takes really long like 30 mins or so, shut off power completely (wait for USB hub rim LED light off, screen off, everything!), then turn car to ACC or RUN again and allows some times to load. Patient is the key!!

3. Navi should appear now. get into hidden menu: Navi -- Settings -- About -- pressing area just above "+ MORE" for around 7 sec View attachment 275189

4. Go to File Manager -- 0:(disk) -- garmin -- gmapsupp.img, check file size of gmapsupp.img which should be around 3-3.5G

5. Click top left menu bar -- actions -- delete -- want to delete file ? -- yes

6. Wait for delete to complete, then quit file manager, go to Test Mode

7. Click next until you are at "Inventory" page. Check if Suppmap, Suppmap1 are shown as erased. Now if they are erased, it means Gmapsupp.img is gone.

8. Click prev all the way, quit the hidden menu, remove USB 1

9. Go to Dealer Mode again -- GarminRecovery Update -- inssert USB 2 this time, start garmin recovery update. This is to do a full installation of CTP13 3.15.

10. Important! Once recovery completes, wait for 3-10 mins allowing system to reboot and load !

11. Important! if system stops at navi loading screen for too long, stop engine or/and fully shut off power (wait for USB hub rim LED light off, screen off, everything!) and re-try the loading.


Once you have full installation of CTP 13 3.15, theoretically you can start map update except that the navi interface might be Chinese. Now I believe you can update to CTP 13 4.08 from this forum or other CTP English version you have under Dealer Mode so that it goes back to English.

From my understanding, it might be OK to just flash your own version of CTP navi from step 9, but to be conservative I would follow full steps.

Hope it helps!!

somebody could help me to bind the europe map to the na version 2022?

i downgraded to ctp13 but the only way i get the update message is when i use a unmodified na 2022.

When i try to bind the europe map to north america 2022 i get a file bigger than 4gb which i cant put on the usb stick
because of the filesystem.
