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 (02/01/2019)
gmapprom.img (02/01/2019)
gmapbmap.img (03/14/2011)
gmaptz.img (03/15/2018)
gmapdem.img (02/01/2019)

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:

065C1IBK.SRX (02/01/2019)
065C1IBL.ASR (02/01/2019)
065C1IBM.ASR (02/01/2019)
065C1IBN.ASR (02/01/2019)
*Note that these file names are ONLY for 2020.10 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:

D3191280A.JCV (02/01/2019)
*Note that this file name is ONLY for the 2020.10 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:

D2656300A.SID (02/01/2019)
D3406270A.SID (02/01/2019)
*Note that these file names are ONLY for 2020.10 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
. │ 065C1IBK.SRX
. │ 065C1IBL.ASR
. │ 065C1IBM.ASR
. │ 065C1IBN.ASR
. │
. ├───JCV
. │ D3191280A.JCV
. │
. └───SID
. D2656300A.SID
. D3406270A.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.
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.

First time updating maps on Charger SXT 2014. The CTP is 14. Any idea what would cause, "Map update was not installed successfully. Please retry update procedure or contact your dealer for assistance." ?

CTP14 has additional security to make it more difficult to manually install maps. You can either downgrade your system to CTP13, or add gmapprom.gma, gmapprom.unl, gmap3d.gma, and gmap3d.unl to your upgrade USB stick, along with all of the other files.

CTP15 is even more secure, so that trick will not work anymore.

I recommend downgrading to CTP13 before installing a map update.

Bingo! It took about 30 seconds to validate, and then prompted, this update may take up to two hours and should not be interrupted - proceed - yes/no. Voila! Thank you Tanbam.

On, but slightly off topic... when I go to the Garmin website, they have some voices and vehicles for download. Anyone have any idea if we can get those to work in our cars? I tried putting them in the Garmin folder on a USB drive and I got an "error on reflashing" message. I would really like to have Darth Vader be the voice of my car.

You can download his voice for Garmin Nuvi products. Doesn't seem to work for the car though. I loaded the Garmin/Voice folder with a couple of the free voices to see if it would work, but... error :( Maybe some of our more experienced / smarter members will have some ideas.

I suspect that it's not possible since our voice does more than just the directions, but... maybe?

Unfortunately, we don't have the ability to easily add voices or vehicles like you can on a nüvi. I've spent some time trying to figure it out, including an attempt to open the radio up and soldering wires to the Garmin module test points in order to try to gain direct write access to the flash memory, but I wasn't successful.

There are still some things I want to try out, but I'll probably wait for the next map update before attempting them.

Merry Christmas and Happy NY.

So my dealer updated me to CTP14 and I am looking to update. I see your quote below. One question...Just so I understand completely...

Pull these files from my Nuvi and place these in the appropriate folders?

You could either downgrade back to CTP13, or add the following files from the nüvi:

Gmapprom.gma
Gmapprom.unl
Gmap3d.gma
Gmap3d.unl

This is only good for CTP14 firmware, which checks to see if those files are present befor allowing the update to begin. These files are related to the map unlocking process, but they'll be keyed to the doner nüvi. You'll still need to manually unlock your map.

For CTP15 firmware, those four files must be present AND be keyed to the actual radio, not the nüvi. There's no way currently available to do this, so you cannot update the maps with files from a nüvi if you're running that firmware.

All CTP13+ radios can run the same firmware, so if you've got CTP15 firmware, you can simply downgrade to one that allows updates. I run CTP15 firmware, but when the new maps come out, I downgrade to CTP13, install the maps, then go back to CTP15.

Thanks as always.
Luckily I am only at CTP14 so I will add the files and run the unlock program on them.
Hope you have a great holiday.

OK, Loaded all the files above as well as all previously required on a USB that I have used many times before.
Unlocked GMAPPROM.IMG with GiMGUNLOCK and also tried a non-unlocked file and I get Update not correct see your dealer message.

I would rather not roll back to CTP13 if not needed, any other suggestions?

Admittedly, I've never tried to update my maps with firmware higher than CTP13 because I don't want to add the extra files, so I'm just going off of other people's recounts.

It only takes a few minutes to revert to CTP13 firmware, and only a few minutes to go back to CTP14/15. Considering how long it takes to install the map updates, it only adds a little more time to the process.

I would probably attribute it to the firmware!

I know you don't want to, but you should downgrade it to CTP13.

After you get the map update done, then you can go back to CTP15 if you would like!

When the next map update comes out, you would just repeat the process.

Thanks guys. I'll do a search and find the CTP13 firmware.
So any benefit over CTP14 and CTP15? The Dealership only brought me up to CTP14.

I finally got it to work on CTP14 without having to down grade to 13. I believe my problem was I didn't have the folder structure right. I did have to unlock 1 or more of the files. Might want to triple check your folder structure.

Thanks, I did the roll back to CTP13, easy... Updated to 2015.30 went well, I think I will just leave it at CTP13 unless anyone knows a reason not too?
