==================================================================================== There are different ways of loading Garmin map image files to the GPSr: (1) using IGM2GPS/Sendmap (easiest), or (2) using Garmin MapSource (provides for viewing the map on the computer). For either of the above, hook up the GPSr to the computer using a USB cable. If you are more adventurous you can instead: (3) load the map image file directly to the memory chip in your GPSr, or (4) load the map image file to the memory chip after removing the chip from your GPSr. ------------------------------------------------------------------------------ NOTES: Unfortunately Garmin GPSr, such as the GPSMap 60CSx, do not provide a way of switching between different map set image files. They can only have *one* map image file loaded at a time. This map image file is *always* called 'gmapsupp.img', no matter what map(s) it contains. That file, by the way, is in the 'Garmin' directory on the memory chip. This means that when you load a new map image file to the GPSr, you will *overwrite* whatever gmapsupp.img map image file is currently there. That is not much of a problem if you can reload that map image file later using MapSource. Although, Garmin GPSr, such as the GPSMap 60CSx, have only a slow USB 1.1 port, so that loading large map image files can take a long time. The more adventurous can avoid this by renaming the current 'gmapsupp.img' file in the 'garmin' directory on the memory chip (perhaps to something like gmapsupp.bak or gmapsupp_name_of_mapset.img). Then switching back is just a matter of renaming files, which is faster than reloading a large gmapsupp.img file over USB 1.1 One way to avoid the need for map set file switching is to have different memory chips for different maps. Another is to combine multiple map files into a single map image file using IMG2GPS. See below. ============================================================================= (1) Using IMG2GPS/Sendmap: --------------------------- Summary: This is the easiest way, and does not involve any changes to your Windows registry. You will not, however, be able to look at the map using Garmin MapSource on your computer. Method: Download the files " 1158544.img" and "87654321.typ" from the online directory "../Maps/Ossipee Mountains" to some convenient place on your computer, such as e.g. "c:\Maps\Ossipee Mountains" (You need only download these two files, ignore the rest.) Use IMG2GPS to upload the "img" file and "typ" file to your GPSr (the combined file uploaded by IMG2GPS will be "gmapsupp.img" in the directory "Garmin" on your GPSr memory chip). Make sure to include the "typ" file so the proper "type" customizations will be in effect. Programs needed: You can download IMG2GPS (free) from http://www.img2gps.co.cc/ Note that IMG2GPS is a windows "GUI" front end for cGPSmapper's Sendmap. You can download Sendmap (free) from http://cgpsmapper.com/ Optional: You can combine the new map with an existing map set, such as some of Garmin's 24k topo maps for the National Parks of the Eastern United States (which does not cover the Ossipee Mountains). To do so, use IMG2GPS and select the downloaded "img" and "typ" files as well as the files for the other maps (perhaps a gmapsupp.img image file copied back from the GPSr after "installing" the other maps using MapSource). Again, make sure to include the proper "typ" file, or the "type" customizations won't be in effect! ===================================================================== (2) Using MapSource: -------------------- Summary: This method first "installs" the maps for use with Garmin's MapSource, so you can view them directly on your computer. MapSource can then upload the map image file to your GPSr. Warning: To "install" maps for use with Garmin MapSource, appropriate registry entries have to be created. Making incorrect additions or modifications to the Windows registry can lead to problems. The accompanying "reg" files create the registry entries automatically when run. They have been tested and should be safe. But it never hurts to back up the registry before making any significant changes. Method: To make the map useable in Garmin MapSource, a "Map Set" has to be created. (a) Make a directory called "c:\Maps\Ossipee Mountains" (with the space in the name). (You have to use this specific directory name, unless you want to edit the file names that are hard-wired into the "reg" registry file). (b) Unzip the "Ossipee Mountains.zip" file from the online directory "Maps/Ossipee Mountains" into the chosen directory on your hard drive (Or, copy all of the files individually). (c) Double click the file "Ossipee Mountains.reg" to "install" the "Map Set" (i.e. create registry entries needed by Garmin MapSource). NOTE: there are two versions of the file, one for 32 bit versions of Windows and one for 64 bit versions of Windows. (d) Launch Garmin MapSource. You should now be able to select the "Ossipee Mountains" map. To do this, select the map set from the combo box in the top left corner, or use "View > Switch to Product". (e) To load the map on the GPSr, select the "Map Selection" tool (five sided polygon icon), and click on the map somewhere. This will highlight the map (in pink). Finally, click on the "Send to Device" icon (or use "Transfer > Send to Device...") Uninstalling: To "uninstall" the "Map Set" double click "uninstall.reg" (this will remove the registry entries you added earlier). NOTE: there are two versions of the file, one for 32 bit versions of Windows and one for 64 bit versions of Windows. You can then delete the actual map files. =====================================================================
