I have 700 Disc Image Files, one for each of the contour maps in Canada.
How I can I combine these files to produce a Disc Image File that I can load into my Nuvi 2689
It depends on the software that produced the maps.
Are these .IMG files from Garmin? If so, you could use GMapTool
In any case, combining all 700 is not possible due to map size limitations
That would depend on the size of all the files combined. They may be quite small.
There was a time when either Garmin's computer software or something in the GPS also had a limit of number of map segments that could be combined. It was an issue when dealing with Garmin's US topo maps where you needed to worry about total file size and total segments.
Does anyone know if this is still an issue?
The limit is not only file size. There is a limit on the number of "tiles" a Garmin map .img file can contain. Some tiles are very small in size and some represent quite large areas.
The map segment limit I don't think will be an issue here. The Garmin nüvis can handle some 3,000 map segments total between all the installed maps before running into issues. Current models may be able to handle more.
We've had people come to this forum in the past with a similar question only to find out the maps were Garmin maps downloaded from a source other than Garmin, which we cannot help them with. Perhaps I'm being too suspicious and untrusting here, but I don't feel comfortable providing additional assistance without knowing the source of the map segments.
The *.img files were topo files from Canada
Unless the government of Canada has copies of its topo maps in a Garmin-compatible format ready for download you didn't get them from Canada. All you did is describe what they are. So where did you get them from?
Canada geomathics, in my case NS Geomathics, has all kinds of maps available in all kinds of formats
I was able to add topo map overlays for my local area 150km radius as 20 tiles, to my tomtom for walking, hunting, it is not inconceivable they have garmin format as well, I have not looked.
Open street maps has maps you can capture as garmin jvc jcv(?) format
Sorry, this is way over my pay grade.
There are some savvy Tech people here, maybe one can help.
I haven't done it in a while, but combining maps isn't difficult with the proper tools. But if the maps are licensed that's a no go.
Go to https://www.gpsfiledepot.com/maps/country/ca. Many of the topo maps are free.
None of those maps cover the entirety of Canada and none of them have the requisite number of map segments mentioned in the opening post. There are only two I know of that do: Garmin Topo Canada, and Ibycus.
If it's a Garmin product then that is piracy, and not to be discussed here. If it's Ibycus Topo, there are YouTube videos by Ibycus' creator explaining how to combine the maps. The lack of response from the OP leads me to believe the product he had was by Garmin, and downloaded from a source other than Garmin.
I am wondering if Ibycus is still active as my e-mail to him was not delivered.
Garmin's Canada Topo Map is way too expensive as the topo elevation on a map is a preference not a requirement for me.
The *.img files were provided by the Federal Government and I was trying to produce a map with yours guys help. But it looks like OSM Map will due as it seems to have more topo features than Garmin's issued Standard Map.
