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 CTP11 & CTP12 radios which are on the 2011 – 2012 Charger, and has a magnifying glass icon for the "Where To":




If you have a 2013 – 2014 Charger, the files needed are different and instructions can be found here:

HOW TO: Map Update on Uconnect CTP13+ (2013 - 2014)

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

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

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

Step 1: Getting update files from the Nuvi

Begin by plugging your Nuvi into the computer and running GARMIN Express. 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 two more folders named "ASR" and "JCV".

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 three files from the ".System" folder in the Nuvi into the "Garmin" folder in the USB stick:

gmapprom.img (03/17/2021)
gmaptz.img (03/08/2021)
gmapbmap.img (03/14/2011)

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:

06PGQW3K.SRX (03/17/2021)
06PGQW3L.ASR (03/17/2021)
06PGQW3M.ASR (03/17/2021)
06PGQW3N.ASR (03/17/2021)
*Note that these file names are ONLY for 2022.10 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:

D3191370A.JCV (03/17/2021)
Large JCV File D3060350A.JCV (851.028 MB)
*Note that this file name is ONLY for the 2022.10 map
**Note that there are three different versions of the JCV file, determined by size! The above listed is the MEDIUM sized one!


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

└───Garmin
. │ gmapprom.img
. │ gmaptz.img
. │ gmapbmap.img
. │
. ├───ASR
. │ 06OT61A8.SRX
. │ 06OT61A9.ASR
. │ 06OT61AA.ASR
. │ 06OT61AB.ASR
. │
. ├───JCV
. │ D3191340A.JCV

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 CTP11/12 system. The other files will just be taking up unnecessary space.

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

Step 2: Generating your unlock code

There are two programs that you will need to generate the unlock code for your map/car combination. You will need to generate a new code for each new map.

The first program is called GMapTool, and it is used to identify the FID number for each new map.

GMapTool can be downloaded from here:

GMapTool

To use this program, install it to your computer. After it is installed, open it and you will be presented with a window.

1) Drag-and-drop gmapprom.img from the USB stick into the blank area under "File Name"
2) Click the "Info" button.
3) Record the FID number.

After you have the FID number, you need to get the 10-digit Device (UNIT) ID number from your radio. You can either find it in the settings menus, or you can wait until the radio prompts you during the install process. It's easier to get it beforehand, though. It will be on a screen that looks similar to this:



Now that you have your Device ID number from your car and the FID number for the map, it's time to generate your 25-digit unlock code. To do this, you need Jetmouse for PC available here:

Jetmouse for PC

After you get the program, open it on your computer.

1) Enter your 10-digit Device (UNIT) ID code in the "Enter your Unit ID here:" box.
2) In the "Select Map Product:" section, scroll to the bottom and choose "<custom mapset>'
3) In the new window, enter the four-digit FID number in the "FID (or MapID):" box and click "OK".
4) Click the "Generate" button in the bottom left corner.
5) Copy the map unlock code (or take a picture of it!)

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

Step 3: Updating the maps in the car

The update package is ready to go into the car. I don't have access to a CTP11/CTP12 right now, so I'm going to try to go from memory...

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.

When 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, including entering in the 25-digit unlock code that you generated earlier.

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!

Hi Eagle7. Perfect, please keep me in the loop. I've been playing around with the Gmaptool, there are some functions where you can split, modify and rejoin the img file. I will keep trying to see if I can reduce the size of the 2022.25 and have our early CTP11 accept it.

Thank you djalbin. Successfully confirmed that 2021.30 maps work. Unable to update ASR/JCV due to lack of space, immediately throws code 0x31A2.
Thank you to both Eagle7 and djalbin! I also can confirm that the 2021.30 maps loaded on to a CTP11 successfully. Now the next step is to get later revisions working. There must be some reason why the CTP11 doesn't like modified maps. There must be some parameter that I am missing, or goes missing when I modify an original map that causes an incompatible map error. I will keep trying at it, but if anyone comes across any info with regards to this error please let me know. It appears the CTP12's don't have this issue, only the CTP11's. Currently I have been experimenting with Mapinstall and Gtoolmap using source files from my 2495LMT. If I try loading the full mapset of 2022.25, it validates but eventually fails due to lack of memory. But if I use Mapinstall to get the file size down, it won't validate and throws a map incompatible error. If I use GMaptool to split the img, remove some maps and rejoin the img, it appears to validate, but then comes with an error that the maps were not install correctly and to redo the process. I am pretty sure that modifying the newer files to get them smaller and have our CTP11's is possible, but I think I am just missing a small piece. Also another option which would be a bit more invasive, would be to look at the Garmin module in the CTP11 and see if there is a way to replace it with one that has a larger memory, or to actually replace the memory chipset on the garmin board. That would be a lot of work, but I believe that would work also. If anyone who reads this has any information please pass it on to me, I know this can be solved someway or another. It seems we are on our own as our vehicles are no longer supported by the manufactures for map updates.

I've replaced a 2016 garmin board into a 2012 radio without issues. Haven't tried 2011, just know that the radio boards are slightly different between 2011-12. Soldering should work, it's tedious work though. Please remember that radio/navi software updates are independent and VIN (year) specific. Always retain source VIN info when swapping to avoid bricking the device when flashing incorrect software.
Alright alright alright....I come with gifts!! After much screwing around with the 2023.10 map release I have created an IMG that will work on EARLY model 430N RHB units. I have a 2011 Jeep Patriot that I bought soon after it was launched and have one of the earlier units. Previously the newest map update I could install was 2021.30. 2022.25 would not work and trying to install the 2022.10 unmodified was a no-go. I figured it was too big at just over 4gb so I gave it a trim by cutting out Canada/Mexico...basically anything that isn't part of the 50 states.

Yes - I know people have released chopped down versions of map updates but from what I've seen they always screw it up and shit is improperly named, versions aren't set, product codes are wrong, etc etc. To top it off they then add insult to injury an insist on hosting their creation on the SLOWEST file hosts known to man. Annoying.

Ok down to what you need to know...

1) Installed the modified gmapprom.img on to my radio that is running firmware 33.02.01. I didn't bother trying to install it with the new JCV (YET) but I've included it anyway if you want to try yourself. I suggest starting without and going from there.

2) As I mentioned...trimmed the map fat. I did a lot of work in GmapTool to make sure settings and structure were as close to the 2021.30 map update as I could get it. EX: mapset name is properly set to "CN North America NT 2023.10 ALL" - not "Bahamas, South Carolina, Georgia" or whatever the hell some of these other modified image releases have come out with in the past.

3) The IMG file clocks in at 2.93 GB (3,150,905,344 bytes). Yep that is less than 2021.30 and under 4GB so if you want to go back in and add some of the stuff I removed...you have room to do so.

4) Format USB, Garmin folder, put in IMG inside folder. That's it. Don't rename it. If you think you need to rename to gmapsupp or whatever then this post isn't for you. This is for people with early NAVs that won't take gmapsupp updates.

5) You'll probably need Jetmouse at some point (I did once early in development) but rest assured this IMG is unlocked.

That is it. If this doesn't work for you then I don't know what to tell you. I did clear NonVol memory through the engineering menu a few times during the course of building this so if you hit a snag then try that shrug If I remember correctly I had just flashed my firmware from 33.01.23 and then cleared it before trying to update. Also...you might need to try flashing twice if you get a PND Update failed the first time....I should have taken notes LOL

Anyway enjoy. Post questions here and I'll try to check in. If I get around to testing the JCV update and it works I'll post here.

did you able to update map , i have the same
good evening my ctp12 rb6 garmin gps stuck at loop boot after successful validation & update to map 2022.10 ...what a luck, i want old GUPDATE.GCD to downgrade gps to older firmware version lower than 4.14 ,,, like 3.xx in order to boot and delete problematic files

can any one share older firmware GUPDATE.GCD for CTP12

Hi, would it be possible to ask you to create a separate image for Canada as well? I'm ready to thank reasonably :).
Hi. I'm new here. I have an RB5 running CTP2011. I bought a nuvi 2597LMT to update my maps. The only update that it offers is 2023.10. From reading the forum, that's too large for CTP2011. I see that 2021.30 has been successfully loaded to the 11 software. Can I get that 2021.30 version for my nuvi through garmin express somehow? Does someone have the file names and folder structure for the 2021.30 map? I'm not a computer person so any help I can get would be appreciated!
2011 Journey RB5 running CTP2011

Peace.
Garmin Express only offers the latest map files for downloading to the Nuvi device. 2023.10 is the latest (most recent) maps.
.
I wish I could get the files to update my 2014 300 GPS :(
Hello! I'm new here! I need some help. Could someone make it so i can update from pendrive? (so I mean ready-made software). Of course I would pay for it! I have a European Chrysler:Lancia Thema LX 2013, CTP2012, Software Version: 4.14
Thank you!
I just bought a 2012 charger. I purchased and updated a used 3590LM with the 49 state map. The only files in the ASR directory are en_US.srd, es_US.srd, and fr_CA.SRD. I've spent a lot of time searching for a resolution with no luck. Anybody have any advice? Thank you.
The 3590LM normally came with the City Navigator NT North America (US Canada and Mexico) maps. Other Garmin Nuvi models (e.g. 1450) came with the 49 lower U.S. states maps. The directory structure and files are different between the two map versions. You need the City Navigator NT North America (US Canada and Mexico) maps to get the files needed by the Uconnect Garmin Nav unit.

CTP12 Update:
The 2022.25 maps (dated Nov 2021) install successfully on a CTP12 unit. I'm not sure about the 2023.10 maps. Members have posted that the 2023.10 maps are too large for the CTP12 memory size and fail the install. I'm interested in hearing from any CTP12 members who have successfully installed 2023.10

CTP11 Update:
The 2021.30 maps (dated Dec 2020) install successfully on a CTP11 unit. I'm not sure about any newer versions. I'm interested in hearing from any CTP11 members who have successfully installed maps newer than 2021.30

*Note that these file names are ONLY for 2023.20 map

This release fixes the problem of the maps being too large for the Uconnect memory.
2023.10 maps were 5.2GB with the gmapprom file being 4GB.
2023.20 maps are 4.1GB with the gmapprom file being 3.3GB

The only peculiar behavior I observed was after loading the maps to the Nuvi. On the first power-up/reboot of the Nuvi it displayed a message saying the maps were over a year old. Subsequent power-up cycles did not repeat the message.

Thanks for all the writeups.

My Nuvi 3590 doesn't get the large JCV files (mine is D9676010A @ 45.4MB) and I'm just now setting for an update.

I've located the file from a Garmin forum as D1279470A.jcv is this the version you see? And what's the advantage using this file for a CPT12 unit?
D1279470A.jcv is the large JCV file for the 2023.20 maps. I don't receive the large JCV automatically with Garmin Express for my Nuvi 2595 ... I have to download it from a Garmin forum if I want it. When the size of the maps were getting larger and larger (some members reporting the maps were exceeding the size of the Uconnect memory) I stopped installing the large JCV.
Now that the map size has been reduced with the 2023.20 maps it's probably safe to install the large JCV. The large JCV will have more junction views than the standard JCV. Depending on where you live/drive the additional junction views may be beneficial. The other consideration is the install time. The USB to Uconnect interface is not the fastest. Transferring 800MB will take longer than 454MB.
(I think your D9676010A @ 45.4MB is actually 454MB)

2023.20 Garmin File list

As an update - I've been trying to update my CTP12 with the 2023.20 using my recently acquired 3590 from Ebay. I ran the GE to update the maps (didn't bother to see what was originally present). GE wanted an SD card to load - which I added a 16GB microSD. The update went thru. I'm not that familiar (yet) with the Garmin files, folders, tools, etc. I placed the 3590 in MTP Mass Storage Mode and connected to my Win10 PC to examine for the files needed. I got a Nuvi I: drive in Explorer.

Per my post above I got ALL files except the D9675010A.JCV (reason I posted for input). In my Nuvi (I:\.System\JCV folder there was a D9676010A.JCV file at 45.4MB). I knew from reading the posts here that this file size was unusual in size. I looked for a 2023.20 compatible JCV file elsewhere and found the D1279470A.JCV AT 819.6MB on another Garmin support website. djalbin pointed out that was the correct file name for a "full" size JCV.

I proceeded to install with all the files from djablbin File Listing for 2023.20 except the JCV was the full size noted above.

The CTP12 proceeded thru a full install process but at the end I got the "no detailed maps found" issue. I was suspecting that there is too many "old" files in memory so I used the File Manager mode to review what was present on the unit. I removed the old JCV files in the JCV folder - there were two gmapprom.jcv (865.8MB) and D2241040A.jcv (108.9MB). I removed all the ASR folder files (*.ASR). I then changed my USB files to just GARMIN\gmapprom.img and ran this to "clean" the CTP12 (per other postings). This ran ok.

So next I reran the USB with the original files and the "full" JCV but this time it failed at the end with the "no detailed maps found" issue. I looked in the CTP12 File Manger and can see the gmapprom.jcv is now the only file in the JCV folder. When I used the CTP12 TEST MODE I can see on the INVENTORY tab display line PROM1 - "CN North America NT 2023.20 ALL US". So it looks like some of the update got installed. The ASR folder had no new files so this didn't load properly and the JCV file only had the gmapprom.jcv and no D1279470A.jcv.

I went back to my 3590 on the PC to review for missing another JCV file. It was then that I noticed another drive letter was on my PC L: (which appears to be the microSD card on the 3590). In this drive I found the D9675010A.jcv (451.4MB) that was on djalbin's file list.

It appears my CTP12 is having trouble with the "full" JCV file. I'm going to try and complete the install again using the D9675010A.jcv (451.4MB) in my USB GARMIN\JCV folder and see if will complete the install.

Any other pointers from those more experienced with these loads? Any other files that I might safely remove from the CTP12 before starting to free the maximum amount of memory space?

btw - that D9676010A.JCV file at 45.4MB appears to be the Canada & Mexico PhotoReal junction file (thats why the size is so much smaller).

Well tonight I proceeded with all the 3590 files (as noted in djablbin's list) including the D9675010A.jcv (451.4MB) file and everything went smoothly to completion. My CTP12 did not like the Full file version of the JCV. I was interested to look at the CTP12/Garmin/JCV folder and there was the gmapprom.jcv 462.3MB [I checked before starting this install and the gmapprom.jcv was 0 bytes). The ASR files were all there as well.

So I guess Full size JCV's don't like my CTP12!
