Superduper67,

I always do this with CN North America NT img files (& using it's corresponding large JCV file direct from Garmin) on my nuvi 775.
At this point (& since you have 4GB on the 765), I suggest you try the below:

1. Download the .gmap version.
2. Unlock it's .tdb file with GarminUnlocker.exe.
3. Use Mapsource to select all tiles, then add "ALL" to the end of the "Map Set Name" (For this map, "CN North America NT 2014.10 ALL").
4. Mapsource>Transfer>Send To Device.
5. Rename the Mapsource "gmapsupp.img" file created in step 4 to "gmapprom.img".
6. Unlock the img by dragging the "gmapprom.img" to the "gimgunlock.exe" of gimgtools-0.03.
7. GMapTool>Write>Set version in header>(for this map, the 1st field "20", 2nd "14" & for the 3rd "Ms" field "0">Write all.

Since Neil's post #35 shows GMapTool's "CN North America NT 2014.10 ALL" map img Log info. of an "official" img from Garmin, I also used an additional step below:

8. ImgTool>File>Open>gmapprom.img, click the "Product Number" button & replace "000-00000-00" with "D233813AG000", press "OK", "Exit".
