    Hello guys,

    I was searching for "how to upload new maps garmin 2720" and to my surprise this thread popped up! What a relief to know that maybe I'll be able to use my Garmin 2720 on my upcoming trip to Mexico!

    Before jumping on the steps described in this thread, I wanted to clarify some questions and make sure I following the correct steps. My 2720 unit currently has the City Navigator 2008 map. I also have access to my original "City Navigator North America Update DVD 2008" with serial number. My computer was replaced and it does not have any Garmin software installed on it.

    So here are my questions, any feedback would be very welcome, as I have not played with this unit in years and have only a vague idea of the language described in this thread:


    1. In order to upload a more recent USA/Mexico map, would I need to use my City Navigator DVD or download fresh software from the web? I am not sure how to start and how to find the required software, hence the question.

    2. Where/how to find newer North America maps compatible with the 2720? It seems like it can take City Navigator 2011. Any other map sources that is recommended?

    3. Would I be able to fit the regions necessary to cover the route below?

    Your easiest option is to use MapInstall which is free software from Garmin, download link:

    Your SP2720 can use modern NT City Navigator mapping. Your DVD version from 2008 is dangerously outdated and it would be foolhardy to use it for such a long trip. Ditto for 2011 map. Your best course would be to obtain the latest 2019.30 version for US/MX as a PC Install version (also commonly referred to as "MapSource Version") and install that on your computer. This forum doesn't supply unlocked Garmin map files however you may be able to find them somewhere else. Best advice is for you to just buy the mapping from Garmin. As you need both US and MX it'd be cheaper to buy all of NA than US & MX separately. Be sure to get the PC install data not an already compiled *.img file.

    3. Would I be able to fit the regions necessary to cover the route below?
    ........
    Yes. Once you have the mapping installed, use MapInstall to select the necessary tiles for your route. As you can see below, I've selected 43 tiles covering NYC to Solidandad region. I did that very quickly so there may even be adjoining tiles selected which aren't necessary. Regardless, it's 43 tiles (selectable map sections) which total only around 700MB and your SP should have far more than that available in region 49 where the primary detail map is stored. You could therefore add more to your final map keeping in mind that rgn49 has probably well over 1GB total space. MI will report the available space as well as the total size needed for the selected area anyway:

    Great feedback Butters, really clear and easy to follow. Thank you.

    In regards to City Navigator 2019, I went to the Garmin store and they only seem to have one offer, either in direct download or SD card format. No mention of "PC install data".

    Also, they state in red: Note: This map is not compatible with StreetPilot® devices.

    What would you do i this scenario? I have read in this thread that some got their 2720 to work with 2011 NT..

    Thanks in advance!

    After further investigating and more reading about this, I came across this site which claims to have free and up to date Maps available for Garmin GPS units. They also have Mexico maps:

    Anyone with experience using this "Open Street Map" with 2720? Would the process be the same or similar to the steps listed under this thread?

    If at compatible and relatively decent map quality, I would be inclined to try it out.

    Thanks in advance!

    That link to the Garmin map store is for purchasing 'out of area maps', like if you have a US localized device but want to additionally purchase EU mapping. To update your OEM map you'd normally use GarminExpress, when you purchase the map you get the option to add it directly to your device and/or load it you your PC so you can select tiles like in the image shown in Post #92. Unfortinately GarminExpress connects with devices only in Mass Storage Mode and your SP cannot do that so you need to use MapUpdater which is old and may not even work properly now:

    Garmin regards all streetpilots as obsolete/end-of-life so you'll get no help from them. The warning on the map store is 'generic' for SPs, however only some SPs cannot use NT mapping, SP26x0 for instance. Certainly SP2720 can use them. I have a US 2720 with Lifetime Maps subscription, I can still update it easily from the PC Data on my computer.

    OSM mapping is quite good and I use it in a SP2620 which isn't NT capable. Certainly SP2720 can use OSM data without problems. I'd not say that OSM is superior to Garmin's NT City Navigators however but it does depend on the area you're operating in and in some cases OSM is at least equal for everyday use.

    Butters, again great feedback. Thank you.

    I am inclined to use OSM to update USA Eastern states in my route and add full Mexico (the img file seems to be only 250 mb, from the OSM website).

    Would you be able to just list the steps necessary, including which software, needed for me to update OSM Eastern States + Mexico on my 2720? I am open to delete any current maps installed on it, if required. I just need some clear steps so I can create the courage to tackle this.

    Thanks in advance,

    It's relatively straight-forward. You can just select only the tiles you want from the site in advance as you said, or take the entire data for NA if you wish because you're going to be downloading data to your PC initially and then using MapInstaller to transfer what you want to the device anyway. So after selecting what you want on the OSM website, request it and when the download page is made available to you select the Windows installer file, named "osm_generic_windows.exe" or similar followed by "Map installer for BaseCamp / MapSource on the Windows platform". Once downloaded, run the EXE as administrator and if Windows smartscreen blocks it, click "more info" then "run anyway". It'll default to install in C:/Garmin/Maps so accept that path which is known to be recognized by MapInstaller. Connect your 2720 by a REAR USB2 port (don't use a USB3 port). Open MapInstaller and select the map in the drop-down at the lower part of MI's GUI (it'll be something like "OSM generic routable(NA)" or similar naming. Then after selecting the tiles you want to send to the SP, click 'Continue', as shown in the pic in Post #92. I'll take a while because SP only has USB1 transfer speed. You could likely also use MapSource to send the tiles to your device without problems however it's no longer supported and causes problems with modern Garmin NT mapping data. OSM is "non-NT" format so it should be ok to use MS too which many ppl find easier to use because it's GUI is bigger than MI's.

    @Butters,

    Okay, this is not as straight-forward as it sounds. This is what I have done so far:

    - installed Mapsource 6.16.3
    - Installed MapInstall
    - Downloaded unlocked City Navigator NT 2017.10 [gmapsupp.img] - I was able to come across this img file while reading more about the procedure.


    I don't know how to install the NT 2017 on the laptop so I can proceed with the next steps in this guide. All the posts in this thread seem to assume NT is already installed on the computer and then they explain how to override the maps inside the 2720.

    I feel bad to say, but I don't know how to open/load this gmapsupp.img into either MapSource or MapInstall. I tried different menus under MapSource and nothing resembling "Load Map" or "Open Map". And MapInstall doesn't show any menu until I connect the 2720 unit, which I left at home...

    After reading this entire thread again, it seems like there is a need for an external program to be able to read the gmapsupp.img map under MapSouce, namely Navnet.exe?

    The link in this thread is broken. If indeed I need this file to install the NT 2017 on my computer, could someone link me to a safe version?

    Thanks in advance!

    Ok, you've decided to go with the Garmin NT CN over the OSM but you've not taken in what i wrote in Post #92: "Be sure to get the PC install data not an already compiled *.img file". You've got an IMG file when you need a .GMAP folder which essentially is a PC Install or MapSource version. It's not possible to install an image file to the PC without firstly reverse-engineering it which loses search function and makes it virtually useless for practical purposes if it's then sent as a reduced area map to your device via MapInstall or MapSource.

    So either go with the OSM as earlier discussed, or search for an unlocked .gmap / PC Install / MapSource Version of Garmin City Navigator US & MX or North America. Then once installed you can send to your SP the specific tiles you need for your route.

    There's a couple of methods to transfer an already compiled IMG file directly to an older device like your SP2720, one of which is discussed exhaustively in this thread, but there's no way the complete .img file you have will fit on your device because it's available space is limited and far less than what's required even by modern map data for US Lower 48 alone.

    Re-read every thing written in my answers to your posts before and ask again for clarification if you don't understand fully. I'm happy to help you with this which is totally do-able, but i cannot supply you with the actual map data due to forum rules and Garmin's EULAs.
