    I got interested and started searching. You can download PDFs of their state maps at: http://www.sct.gob.mx/planeacion/cartografia/mapa-por-estado.
    If you look to the right, you see that they also have newer digital maps you can download, but they look to be the same thing as the slightly older maps but smaller in size.

    They have an office in Mexicali. Unfortunatley, it's a 45 minute walk from the border so one can't just pop in to get one. I don't know what the border crossing is like in a vehicle so it might take about the same time to go in a car or I guess one could take a taxi. The address is: Ejército Nacional 780, Nueva, 21100 Mexicali, B.C., Mexico. The phone number is: +52 686 568 9236

    I think the best GPS maps for anywhere in the world, these days, including Mexico are the Open Street Maps, downloaded from:

    http://garmin.openstreetmap.nl/

    Leave the executable files with their original name, as it's then easier to convince Win 10 and your antivirus program to run them.

    Rename the .img files to describe what they are. If your GPS can only find gmapsupp.img files, then you can give them that name just before uploading to the GPS.

    OSM MAPS for Garmin and other satnav devices.

    Here is a direct link to the OpenStreetMap OSM website with free downloadable basemaps for Garmin devices using Mapsource or Basecamp. A little googling around may yield a similar page for other brand devices.

    http://garmin.openstreetmap.nl/

    Simply choose Generic Routable type, region (Mexico in this case), and download the executable map pack. The executable file will install the OSM basemap for Mexico into Basecamp or Mapsource, similarly to City Navigator or other map set. Once the basemap is loaded into Basecamp/Mapsource, you can upload the map into your Garmin unit, alongside the Mexico region of city navigator if you have space on the unit.

    I've installed the OSM maps in my Garmin 276c and they show up and work fine, including auto-routing. To best of my knowledge, the latest Official Garmin maps available for the old 276c are the City Navigator 2013 which I have. I've found on previous trips that the Garmin City Nav 2013 maps have a usable amount of major, minor, and even dirt, roads in Mexico, though not some of the newer roads or dirt roads. The OSM maps seem to have all of the latest roads as well as some of the smaller local dirt roads. It's a good additional reference and can be loaded into your gps unit alongside your existing City Nav or other maps as long as you've got space on your data card.

    On another note, the iOS and Android app Maps.me is free, uses the same free OSM map data, and works offline. It's a great companion to your GPS for large scale mapping and route planning.

    Hope this helps...

    Cheers!

    Here is a link to a site with pre-built maps for Mexico and South America...plus most of the rest of the world. Also use OpenStreetMaps.

    I have a Zumo 590 I bought in Europe so the base map Installed is Europe City Select . I bought N. America City Select and it’s maps of Mexico are pretty good. It’s not Life Time maps so Garmin won’t update it but that’s fine. My problem now is that I’ve bought GPSKevin’s Continental Trail chip for a ride this summer and I would like to install it to either my base memory of the Zumo or the City Select chip and I don’t know how to do this.

    Can anyone give me a clue as to how to do this?

    I've done it before with a program called GMap Tool. Google it and you'll find resources of how to combine the two images into one.
    It's very important that you copy the images from the chips you've bought and place them on your desktop and keep the original chips separate and safe from any changes. (In fact, I highly recommend you copy both chips and put the copies on a back-up thumb drive, DVD or external hard drive). Purchase yourself a blank chip (4GB), and place your final image on it. You'll be combining the N. America City Select and GPSKevin's Continental Trail images into one image. It has to go into a folder named garmin
    Hope this helps

    It would have helped except I forgot to mention I use a Mac. The Mac version of Gmap Tool is over my head. (My head isn't all that high.) I really don't need to combine the two files if I could just load GPSKevin's map as a route or series of routes. I just don't want to have to switch chips every time I get off the trail, for example, going into a town to a motel, etc. Is there any way to save the CDT file to BaseCamp, then just load it to the ZUMO.

    I just went back and looked at BaseCamp and, believe it or not, the Continental Divide map is on there. Problem is, I can select it, download it, then disconnect the GPS from the computer and look for it, and can't find it on the GPS. When I look at the N. American map on the GPS there is no sign of the trail. Frustrating.

    Ah, Basecamp and a Mac....
    I tried Basecamp for a while and it was way over my head (or I'm just too old of a dog to learn), so went back to Mapsource... I can do everything I need to do with it...
    I've always been a PC guy.. I have an iPhone and find it confusing at times, so no Apple computer for me... besides, all the programs I need to use run well on my PC and are within my head height!!

    I don't have a Zumo either so don't know what they're capable of in regards to multiple images on an SD card, but, you might try this.
    FIRST, back up the original images before messing with them. I hope you've done this already......
    One image (N.A. City Select) should be named either gmapprom or gmapsupp (NOTE: the name has to consist of 8 characters)
    The second image could be named gmapsup1
    Both images are placed within a folder named garmin on the SD card.
    Navigate to your map selection page on your Zumo and select (if they show up on the selection page) both maps... then see if they show up on the gps, or try selecting one or the other and see if either of those show up. If the latter works, then you can switch between maps as you need them.
    If the Continental Divide map is a transparent map, it should overlay the NA City Select. If it is a full map with mapping of the Continental Divide and surrounding area, then only one of the two maps can be displayed on your gps at a time.

    If that doesn't work, then try this:
    One image (N.A. City Select) could be named gmapsup1 (NOTE: the name has to consist of 8 characters)
    The second image could be named gmapsup2
    Both images are placed within a folder named garmin on the SD card.
    Navigate to your map selection page on your Zumo and select (if they show up on the selection page) both maps... then see if they show up on the gps, or try selecting one or the other and see if either of those show up. If the latter works, then you can switch between maps as you need them.

    If you were close to Yuma AZ I might be able to help you out (on a PC.......)

    If any inmates out there have a better way of explaining it, please, chime in.
