Hmmmm well I got the Ibycus map working on the Montana. I reformated the SD card while it was in the GPS and put the folder Garmin on it. I then copyied the CA-Central map in the folder and it did not work. I deleted the CA-Central map and copied the gmapsupp (Ibycus) in the folder. The map just show up on the main screen? It is not in the map menu or anything like I can't enable or disable cause it is not in the map menu. I'm good with that as that is all I wanted for now. Thanks for all the help. Just in time for hunting season hopefully put the GPS to good use. Thanks again everyone.
If it is any help I have an Garmin 60CSx with the Ibycus Canada Topo on it that I loaded years ago. If I can get that map on the new Montana I would be happy with that. I did sort of try this by copying the gmapsupp file that is a disk image file to a folder on the computer I'm using. Not sure how to get that file onto the Montana or if it would just work like that.
Yes it is a brand new GPS it does have some waypoints and a few tracks on it but not other maps other than what came on it. I'm not sure I follow what you were talking about with the MAC version of the map? I'm using a windows 10 computer and I do have basecamp I think the lastest version and also mapinstall.
Hmmm I did not find the setting for internal or external maps. I did make the folder change on the SD card. I also have renamed the map to Ontariomap but still nothing of that name comes up. I'm looking in the map tab it brings up a blank screen now because I have all the other maps disabled. I hit the 3 bars that brings up the map menu then hit map information select map. When it hit that brings up the maps Worldwide DEM, CA Brampton, BirdsEye and few more. Like I said I have disabled all of those maps. Am I maybe looking in the wrong spot? Should I default the GPS and start over? I must be doing something wrong its a brand new GPS. Thanks for all the help so far.
Ok so I did not format the 32Gb I installed. Thought I read somewhere I didn't have to. I have formatted now as FAT32 with a windows computer and have installed in the GPS. I named the SD card Derek. After plugging in the GPS to computer the GPS comes up as Montana F: and the internal storage comes up as Derek G: There is no folders under G. There is still a Garmin folder under F. The CA-Central file is under the internal G in the Garmin folder.
The other .img files in the internal storage are gmapbmap 47,624Kb and gmaptz 572Kb The CA-Central file is 1,333,568Kb that is in the internal storage. The file on the computer is the same size.
Ok the Montana 680 I have is not showing in the map I moved to the Garmin folder of the GPS. I downloaded the map and unzipped it and saved to my computer. It is now an .img file. I moved it from the computer to the Garmin folder in the GPS. There are other .img files where I put this one. I go to the maps screen and there is nothing in there that says CA-Central. The instructions on the map down load screen says I should just be able to move the windows version of the .img file to my GPS. I must be missing something. Thanks
