Well, it's finally happened!

As I speculated in the map update watch thread, the full CN NA map has now exceeded 4 GB and Garmin has delivered 2023.20 as two map files. Note that this has been done with the CN EU map for several years now.

On my nuvi 3597, it shows up on the Settings/MyMaps as 2 maps, with US being separate from Canada & Mexico. The US map was put in internal storage as gmapprom, the second map file was put on the SD card in the \Map folder and is named D9644010A.It will be interesting to see how this is handled on my two old nuvi devices (755T and 855) which have smaller internal memory and more severe map file naming restrictions. I am guessing the 755 will handle it but I don't hold much hope for the 855, as Garmin Express doesn't even recognize use of the SD card on that series. I will follow up later with the results.

Edit: It appears that there is only one JCV file on the 3597 even though the map is split into two .img files. Apparently the junction views can be served to both map segments from one file.

Second Edit: I also don't know what impact this will have on cloning. Maybe sussamb knows the answer to that. I guess I will find out when I try to update my old nuvi 855 using cloning.

Map update CN 2023.20

Happened to notice GE reporting that a map update was available earlier today for my DriveSmart 55, before I saw the posts here... downloading is in progress!

Thanks

Thanks for letting us all know. I do commend Garmin for their thought, now that two files are needed for the map itself, that all of the USA is in one file while all of Canada and Mexico are in the second file.

GE recognizing use of SD card on older series Garmins

alandb, I had the same problem with my Nuvi 760... in the past GE would find the SD card and install maps there when there was not enough internal room. With the last update 2023.10, it no longer would. I verified it was not a card or device problem, because it would show up in Windows Explorer. It was apparently a GE problem. Then, I got a new laptop running Windows 11, installed the latest GE, and guess what - GE found the SD card and let me install the map update to it! I tried it again on the old computer and it still did not work. Hope this helps others with older Garmins who thought they would no longer be able to get the latest map updates.

Nuvi 755T, 2023.20, first attempt.

I have finished with my first attempt at updating my old nuvi 755T to the 2023.20 CN NA map. I just used native Garmin Express (no cloning). It recognized the SD card just fine, completed sucessfully, and I thought I was getting the full CN NA, but when I booted the device up, all I had was "CN NA ALL US", in other words minus Canada and Mexico. I thought GE said I was getting full NA, but maybe I missed the naming distinction between "full NA" and "All US". The "All US" map file was installed on the SD card as gmapsup1. The JCV files were installed in internal memory. There was plenty of room on the 8 GB SD card to hold both sections of the map files and the file naming rules on the 7x5 series should allow both a gmapsupp and a gmapsup1 file, but apparently Garmin Express wasn't willing to install it that way.

I did get both versions of the large JCV file. That is still a mystery to me as I don't think both of these files are required. I have not found any convincing explanation about why Garmin is downloading the extra JCV file on these old devices.

When I get time, I will retry the map update using cloning with a large thumb drive. That way, Garmin Express will not need to split the files across internal and external storage. I don't think it will make a difference, but I have to give it a try just out of curiosity.

As I said before, I have much less hope of getting full NA on my old nuvi 855, and cloning will be the only hope for that old device. For those of you still trying to do map updates on old StreetPilot and nuvi 3xx/6xx devices with 2GB file size limits ... well good luck!

I don't use my old nuvi 755T and 855 devices any more. My only motivation for trying to do the map updates is to satisfy my own curiosity and to help others who might still be actively using these old units. The fact that Garmin has kept them usable and viable for this long is remarkable!

Follow Up Edit: OK, I couldn't resist the temptation, so I tried the update on my 755T with cloning using a 128 GB thumb drive. This time I carefully checked the map details on GE. It definitely said City Navigator North America with no indication that I was getting a reduced region. I let it go to completion and got the same files I did without cloning. The only difference is that the map file was named gmapprom instead of gmapsup1 (because GE isn't smart enough to recognize cloning, it "thinks" it is installing to internal memory). I am guessing Garmin Express will not install both map segments to devices that don't support unrestricted map naming to the \Map folder. Too bad, because a device like the nuvi 7xx could easily support two maps named gmapsupp and gmapsup1. It may be possible to use MapInstall to install the additional regions (Canada and Mexico) although I am pretty sure that method would not support junction view in those regions. I am not motivated enough to try the MapInstall technique. Maybe if someone else tries, they can post the results. Oh well ... like I said before, it is remarkable that these old devices still work at all!

No change when cloning modern devices, even my 1490 works fine, you just get 2 map files to copy across. Not sure how it would work on devices older than the 1490 as I don't have any.

As I expect both of you assumed would be the case, the nuvi 750 with SD card was offered the full update by Garmin Express, but like alandb's nuvi, only installed the All US map. The nearly 4GB map file was installed to the SD card.

The nuvi 855 received, as it had in the recent several updates, just the Lower 49 State US map. Since I only update the 855 to see what it does and to keep it map-update-eligible, I stopped using the clone method to force a full North America update and also stopped replacing the installed jcv file with the Large jcv file.

This does bring up an interesting issue though, for users of the old devices like the 750, who live in Canada or Mexico. It doesn't appear that they can request the new Canada/Mexico single map and will only be offered the All USA single map. crying

Only US map for Nuvi 265

My Nuv1 2597 had no problems on the update and showed the two 2023.20 map sets. The Nuvi 265 that has had a SD card installed for sometimes and has always had a full map set but only received the single US map this time.

Couple of Comments

Using a Nuvi 2598. Like others two maps are now listed.

Update Maps
CN North America NT 2023.20 ALL Canada & Mexico
CN North America NT 2023.20 ALL US

Unlike the past one or two map updates, there doesn't appear to be anything stored on the external microSD card that I had to start using a few map updates back when the map update indicated the internal storage was full. In the past there was a few hundred MB stored on the external storage, none apparently with this map update.

CraigW, that thought about requesting Canada & Mexico instead of All US occurred to me also. But I was unable to get Garmin Express give me a choice on regions on my 755T or 855. I thought if I could install just Canada & Mexico, I might be able to use cloning to get All US as a second file and manually copy it over to the SD. But no such luck as GE wouldn't offer that region. If someone is a resident of either of those countries and wanting to update the map on an old device, it might be worth a call to Garmin support to see if they have a solution.

CraigW, I am curious about one thing when you update the 855 to Lower 49 using GE without cloning. Do you get corresponding new .ASR and .SRX voice recognition files in the \ASR folder with the map update? The one time I tried that, I did not get new versions of these files, so I went back to using the cloning method which gave me the full NA and corresponding updated .ASR and .SRX files.

I haven't completed the 2023.20 map update (with cloning) on my 855, so I have yet to find out what problems might turn up. I hope to work on that later today.

I think what that tells me is that the nuvi 1xxx series devices allow map files in the \Map folder and have flexible map file naming rules. The older devices like the 2xx, 7xx and 8xx nuvi series, require maps to be in the \Garmin folder (both internal and SD) and have very strict map naming rules (gmapprom, gmapsupp, gmapsup1). That is probably why GE refuses to download both segments of the full NA map on these old devices.

Nuvi 855T, 2023.20 via cloning.

I have completed the 2023.20 map update on my old nuvi 855 using the cloning method. As in the past several updates, I had to start with an old version of GarminDevice.xml from a backup. If I tried to use the current version, Garmin Express would only offer the lower 49, not the full CN NA. It does make me wonder if there is any difference between the "Lower 49" map and the "All US" map? I suppose "All US" includes Alaska?

The cloning process completed without incident. Just like with my nuvi 755T, I only got the All US map and not the Canada & Mexico map. I was able to copy the map over to the SD card (renamed from gmapprom to gmapsupp). I copied the updated voice recognition files in the \ASR folder to internal memory. I also copied the large JCV file from my 755T to internal memory. The 855 booted up OK and showed the All US map in the Settings/MapInfo screen. I ran a route in simulation mode so I could check the junction views, and it was displaying the hi-res views from the large JCV file just fine.

So my conclusion is that the 855 is still capable of being updated via cloning and just like the nuvi 2xx and 7xx series you will only be able to get the All US map and not the Canada and Mexico map.

alandb, using GE to install Lower 49 states to my nuvi 855 does not show new files in the ASR folder. There is a single asr file and single srx file in the folder and each has a file date from 2017.

I updated my 250W and i now have a useless GPS for Canada.Is there a way to delete it and install the previous map 2023.10?

One way

One way is to use Garmin MapInstall.

You can install 2 separate maps (or more) and only install the portions that you need/want.

You will probably have to install the current map "to your computer", using GE, in order for this to work.

If you did not "uninstall" the last map from your computer, you can use MapInstall to replace the current map. There is (or used to be) a page at Garmin Support to install previous versions.

Well I tried Mapinstall and indicated an update which I did not do and 2023.10 was still in the PC. I picked the areas that I travel In Ontario,and New york State,and downloaded them and now I have a useful GPS again.Now I am nervous to update my 3597.

The Home of BLUMARU HOUNDS

3597 not a problem

The 3597 not a problem. GE installed the new map flawlessly to my 3597 as well as my DriveSmart 76.

It's the older Garmins that have a problem. They are limited to a 2 Gb map size and have to have multiple maps installed (usually requires a SD card) and GE can't process them, apparently because Garmin considers them obsolete and won't update GE for them. In later models memory was increased to 4 Gb. And in the latest models it is now 8 Gb, I think as. Gamin isn't too clear in their specs.

Since the map is now over 4 Gb, GE will install 2 maps to the GPS with a 4 GB map size. That is what it did to my 357. As far as I can tell, there is only 1 map on the DriveSmart 76. I do not have a SD card in the DS 76.

no ill effects

I detected a difference from the previous map. Completely unimportant, yet a difference.

I used to drive near the administrative office of our local school district without any messaging. Now it seems to have been reclassified as a school with kiddos and attendant messaging.

In this case there are no ill effects. Someone from OOT (out of town) will be warned to watch out for kids that aren't there. No harm done. There is no change in the real speed limit or the map's speed limit. No harm done. Who cares. Sorry I troubled you with message without information. (Anyone who isn’t bored enough should read Claude Shannon ( https://en.wikipedia.org/wiki/Claude_Shannon as an intro to information theory).

2 maps, one file?

I have a Drivesmart 61. on the "my maps" you can see what appears to be two maps, all of the US & all of Mexico and Canada, two listings as you can see in this photo:

https://i.postimg.cc/sgz5rLBt/292759240-708918713511161-5615...

However, when search my 'hidden' directory I found only one "gmapprom.img" file?

So is it two maps or one?

Don't forget the cleanup

Map updates using GE leave behind older version of maps, each about 6 GB in size at the following Windows location. Probably something similar on a MAc machine.

Cant find old maps ! Where are they ?

Greetings from Sweden ! Windows 10, and Garmin Drivesmart 66. I only download and install maps directly to my 66. After installation I cant find the map on: %programdata%garmincoreservicedownloadsmap

Earlirer the map always was at this place and I could easily delete it. But not any longer, I have searched the internet for answer to this but so far havent found anyone that can tell me where the map is ?????

The Garmin map at: %programdata% is only about 8 Mb so it isnt there ?

Can someone please tell me in easy steps where to find maps so I can delete them ?

Normally the maps and other Garmin Express downloads are save into the following location on Windows so they can be installed:
C:\ProgramData\GARMIN\CoreService\Downloads

If it is not there, then open the Garmin Express program, select your Garmin unit that had it's maps updated. Select Map Details, then Map Options. Look at the Install to Computer section of the Map Options page where it should list the Install Location where the maps were installed to. Check there to see if the downloaded map installer files are located in that directory.

Another option is to use a hard drive or folder analyzer program to search the hard drive for which locations are using storage space. The map install runs upwards of 8GB so it may be easy to find such a large folder using such space/storage analyzer programs.

Very interesting

I connected my DriveLuxe 51 to my PC and searched the entire device, first for any file starting gmap, then searching for any file containing .img.

The search for files starting with gmap yielded no likely files.

For .img files, I found six, and excluding the basemap, time zone, and gmapprom.img USA mapfile, that leaves three files. Assuming Canada/Mexico is a large file, the most likely candidates are D9644010A.img in the Map folder which is 0.98GB. There's also in the .system's Map folder, D4919260A.img at 98.6MB, as well as the D6460190A.img file at 33.9MB. These three files could be the Canada/Mexico map, the Parkopedia "map" and the Foursquare "map."

Maybe someone could try renaming each of these "D" files, one at a time, then booting the GPS to see if the Canada/Mexico map, Parko, and Foursq "maps" disappear in the device's myMaps screen. I'm not going to try this since I don't know what the effect would be on my DL 51 and don't want to take the risk.

"bennor3814" mentioned using a utility and I recommend Treesize free (see https://www.jam-software.com/treesize_free?ca=1). After installing and opening the utility, click on the directory to search (top left) and change to drive C. A tree is then built, largest at the top. Expand the largest items using ">" and you should find the Garmin related items. Very fast utility.

Thanks for the heads up, but

The install went as smooth as it ever does.

I don't know what's improved.. however this one is a "lot" worse on the "road ahead feature". Skips major intersections and shows minor crossroads next, often several intersections ahead of where you actually are.

The last map was bad enough, this one is noticeably worse.

Thank you, I have looked in the Programdata/Garmin map, but its only 8 mb big and shows hidden files as well. But no 8 Gb file. i guess its something connected with the brand new Drivesmart 66 that dont saves a map on the PC when I install it to the unit. Oh ! Well it was a nice try I appriciate your answer.

Waiting for 2023.25 before

Waiting for 2023.25 before updating mine... Or maybe 2023.30...

Yep

Yeah, I got 5 units of varying ages here to update, but I think I'm going to wait at least a month.

I got "burned" on the last release of Extress when it messed up my watch.
And, I'm not going anywhere that my current maps can't find.

Maybe I'll wait for the next map release that's bound to come before the end of the year.

I am pretty sure the D9644010A.img in the \Map folder is the Canada & Mexico map as that file shows up on the nuvi 3597 for this update. The other two "D" maps are not on the 3597 which does not have the Parkopedia and Foursquare features.

Maybe I'll wait for the next map release that's bound to come before the end of the year.

I think Im going to download this, but not actually install it. Garminexpress gives no choice in map version selection.

Thank You for the info Will

I have a Drivesmart 61. on the "my maps" you can see what appears to be two maps, all of the US & all of Mexico and Canada, two listings as you can see in this photo:

https://i.postimg.cc/sgz5rLBt/292759240-708918713511161-5615...

However, when search my 'hidden' directory I found only one "gmapprom.img" file?

So is it two maps or one?

I connected my DriveLuxe 51 to my PC and searched the entire device, first for any file starting gmap, then searching for any file containing .img.

The search for files starting with gmap yielded no likely files.

For .img files, I found six, and excluding the basemap, time zone, and gmapprom.img USA mapfile, that leaves three files. Assuming Canada/Mexico is a large file, the most likely candidates are D9644010A.img in the Map folder which is 0.98GB. There's also in the .system's Map folder, D4919260A.img at 98.6MB, as well as the D6460190A.img file at 33.9MB. These three files could be the Canada/Mexico map, the Parkopedia "map" and the Foursquare "map."

Maybe someone could try renaming each of these "D" files, one at a time, then booting the GPS to see if the Canada/Mexico map, Parko, and Foursq "maps" disappear in the device's myMaps screen. I'm not going to try this since I don't know what the effect would be on my DL 51 and don't want to take the risk.

I am pretty sure the D9644010A.img in the Map folder is the Canada & Mexico map as that file shows up on the nuvi 3597 for this update. The other two "D" maps are not on the 3597 which does not have the Parkopedia and Foursquare features.

Wonder why they split it like this in unit's that have the space.

2597 & DS 76

My 3597 with 8 Gb micro SD card has:

CN North America NT 2023.20 ALL Canada & Mexico
CN North America NT 2023.20 ALL US
Cnna - North America - North America DEM
CN North America NT 2023.20 Basic 3D

DS 76 with NO SD card:

CN North America NT 2023.20 POIs
CN North America NT 2023.20 Foursquare
CN North America NT 2023.20 ALL Canada & Mexico
CN North America NT 2023.20 ALL US
CN North America NT 2023.20 Parkopedia
National Parks V2
North America DEM
CN North America Basic 3D

Please note: There are a lot of roads in other countries that are now included. For instance, some major roads are now showing up from Guatemala down to French Guyana on both units. The map even shows a road in Cuba! Zoom out and pan down to Central America and Northern South America. Then zoom in and pan along the coast. Don't know if this is available on older Garmins, like my former 660 if you use MapInstall and install ALL the available sections. If you use MapInstall, don't forget Hawaii.

Nothing ...

@soberbyker

... to do with space. Its a restriction of the FAT32 system which cannot handle files over 4Gb

fast update

Took only 25 minutes to download and install the new 2023.20 map update to my computer and drive smart 55. Noticed it added the driveways in the parking lot areas near my home.

I downloaded the latest maps

I downloaded the latest maps to my old 255W with no problems. Just last week I installed an 16GB micro sd card to my Garmin. Don't know it this was the reason for the ease of intalling with no problems or not.

Well

I don't think there's any compelling reason to do that.
My biggest reason for not doing is because GE will install BaseCamp again, and I don't wnat, or need, that.

It's been a long time since I haven't had Basecamp but I think Basecamp installs only if you ask the map update to install to the GPS & computer, or to computer alone. If you accept the default "install to GPS," I don't think Basecamp is installed on your computer.
