    Jerry, this is the way to go for some of your big projects! I don't load tracks anymore, I use GPX2img pretty much all the time now.

    You could put ALL of SMTS (or GWT, or Mex2Can, or even ALL of your track files together) on a single map overlay. Then load it onto the uSD card in your GPS along with R&R. Then copy that IMG file to other uSD cards or post that map file on the internet for anyone to copy themselves. Call it "Coundown's map to the World"!

    My guess is such a SUPER map would load just fine into just about any Garmin, including Nuvi and Zumo.

    I didn't think about that at first, but this might actually work to load tracks onto a Zumo which normally turns tracks into routes.

    Not exactly.

    On rides, customer needs to turn on and off tracks as they ride.

    On my big files like Death Valley on GPSXchange.com people need to cut and paste tracks t plan their trip then load into GPS (they could use it).

    I think the big application is for OHV riding areas like Jawbone or Rand Mts with designated routes and many closed existilng routes. Some forest in the midwest has it available after travel management. Riders could just download the IMG file with no maps and have a good ride.

    For my use, I think just moving up to 78 with 200 tracks of 2,000 points does what I want.

    Good point on (useless to me) GPSs that don't take tracks like Zumo.

    I've tried both programs but prefer IMGfromGPX - but you have to be on the internet when you use it.

    You can name the map overlay when you build it, and you have to give each map overlay a unique map number.

    The tracks (or routes, IMGfromGPX will also convert routes) will be the color you had selected in Mapsource unless you over ride it at compile time. So you could color code your main route in one color, and alternate routes in other colors depending on the difficulty.

    Just to test things out I built a really big overlay - TAT, TCAT, TET, CDR, PCQ - which came in at 1.4mb!

    I've loaded overlays on NUVI's and they worked fine.... which is a good deal since you can't do much else with them.

    My favourite use for gpx2img is creating an image of the baja 1000 route, which is well over several thousand track points. My poor CSx only likes 500 or less, so trail detail is severely compromised.

    I purchased the gpx2img program, went through all the steps to add the map to my Garmin 76CSX. When I pushed transfer to load it into the GPS a window popped up and said that I was about to delete Garmin data that was preloaded in the gps. I am assuming that it meant the micro sd card data City Navigator 2012? The prompt said they recommended not to continue.
    Any ideas?

    I figured if Big Dog could do it anyone could? LOL
    Guess not

    I have an old Nuvi and didnt care if it did delete the data on it so I tried it. Data loaded fine and shows up good. All my tracks are there.
    Wonder if I need to remove the City Navigator micro sd and try to load it then?
    I didnt get the prompt that said I was going to delete data with it. It all went smooth.
    Only got the prompt with my 76CSX.

    The only map on your 76csx is loaded on the micro sd card. That will be City Navigator. If you purchased CN on a SD card only, you cannot load the gpx2img map with it. Mapsource will want to delete the original map and replace with the new gpx2img map.
    If you have City Navigator loaded on your computer and have a license for your CN linked to your 76csx, then you can load the gpx2img file to your gps... BUT, you'll have to re-send CN along with any other maps you want, gpx2img, topo maps etc. They will transfer to your SD card and replace anything that's on it. That's why everyone recommends to copy what's on the original SD card to your desktop, disc or whatever FIRST. Or, use a new SD card. The new image will contain all the maps you transfered, including gpx2img. You don't have to have your gps plugged into your computer, you can transfer directly to you SD card plugged into your computer card slot. It transfers a lot faster.
    Just so you know, on the SD card, you will only have one image (gmapsupp.img) that contain all the maps or map that you transferred by mapsourse.

    Your Nuvi has an internal memory, which has the original map written to, so I think when you transferred gpx2img to it, it wrote to the SD card, otherwise you would've had the warning that you were about to delete the map. The map in the interanl memory is called gmapprom.img and the map on the sd card is called gmapsupp.img

    Some use Basecamp, but I prefer mapsource to transfer maps and tracks.

    There's a bit of a tutorial on http://www.gpx2img.com/ website.

    Hope this makes some sense.... Maybe Mark (BigDog) can chime in to explain it a bit better.
    Cheers

    Thanks , This was what I was NOT doing. All I needed was to highlight the gpximg map with the map tool along with any other county maps. (roads and rec)

    Still using this little program (gpx2img) it works great with my 376's with their 15 track limit. I can easily load up 40 or more tracks using the img file, and then load an additional 15 standard trks.

    Big Dog just told me about this (GPX2IMG) the other day and I like it.
    I do have a problem thou. I have a nuvi 500 and loaded a pic image on it, very easy. Map shows up but when I zoom in it disappears. I have only been able to get it to show down to 1.2miles with least detail and 8miles with more detail.

    I have tried different settings with no difference.

    Got any ideas? Thanks

    It should just be a "transparent" map overlay that is available at any zoom level.

    I honestly don't have any ideas as I've only tried this on my 478/376/276 and it works fine. I can turn it on/off in the map information screen, but if its on, its always visible at any zoom level.

    This is a post I made on the Nuvi thread - this works on any Garmin GPSmap with a memory slot.
    It's relevant to this discussion.
    I have built overlays of over 100 tracks and 10s of thousands of track points, still only 1-2mb. I also have an overlay of over 12,000 waypoints - all the publicly owned campgrounds in the US. Easier to build overlays of waypoints separately.

    On one of my Nuvi's, the base CN was in internal memory and I had an SD card with R&R, Topo and some overlays. Updated the CN, Garmin said there wasn't enough internal memory did I want to load it on the SD? When I said yes, it temporalily saved my custom gpsmapimg file to the computer, loaded the new larger CN to the SD card, then loaded my custom gpsmapimg file back to internal memory! So I've still got both! Way too cool!



    Another way around it

    <hr style="color:#575757; background-color:#575757" size="1"> If you want to ride a pre-planned route that you build ahead of time on your computer there is another method that you can use that will work on any Nuvi that has a memory card slot.

    1. Build the route in Basecamp or Mapsource, save it.

    2. Copy it over to a piece of software called IMGfromGPX which is found here -
    http://www.javawa.nl/imgfromgpx_en.html
    Your file can be either a GPX file or a standard Garmin GDB file.

    3. Give it a unique name and Map ID number (look up list of Map ID numbers currently used)
    A good list is found here - http://www.javawa.nl/mapids.html
    You can use a number somebody else is using, just can't have both maps loaded at the same time.

    4. Create the Overlay map. The TYP file will tell how your track lines will look, NT means No Text.

    5. Install the overlay map into Basecamp or MapSource (go to the directory where you created it, go to the .reg directory for Mapsource and run install)
    (in basecamp, go to the directory where you created it, go to the .gmap (I think) directory to associate it (Sorry, I don't use Basecamp!)

    6. Go into Basecamp or Mapsource, select the overlay map to be displayed, select the overlay map to be downloaded to the unit, (if you want to download more overlay maps, select them now), download it to an SD or microSD card.

    7. Put the memory card into the Nuvi, go to utilities/configuration/maps/information (based upon a Spanish language unit - I'm in Costa Rica on vacation and don't have any units with me!) and turn on/off the overlay map. It will show your route as a colored line on top of the existing map in the unit. The color of the line is one of the 8 base colors available when you create the route. Some colors show better when zoomed out further - I think off hand yellow, red, green.

    You can have MANY overlay maps loaded at the same time as long as they each have unique names/numbers and the map set to be loaded onto the memory card is created at the same time.

    Also note that IMGfromGPX talks about converting tracks - it originally needed tracks to convert - but it has been updated to convert routes to tracks automatically before it builds the overlay map.

    You can also tell it to label the tracks/routes in the overlay map with the track/route name - this is what it's talking about when says text/no text.

    You can build an overlay map with a mix of tracks/routes, even waypoints.

    Waypoints gets harder - each set of waypoints with a different symbol has to be in a separate file before being loaded into IMGfromGPX. You get waypoint symbol, name, and telephone number if it's in the right waypoint field for telephone. Waypoints are searchable.

    An overlay map doesn't take ANY routes/tracks/waypoints if your unit supports it - it's a map, remember?
