    If it's a PARTIAL NA image file that's less in size than the available space on your SP then you can send it using [Only registered and activated users can see links. ] via command line: [Only registered and activated users can see links. ]. If loading to rgn49 use "gmapprom.img" naming. If rgn10 it's "gmapsupp.img".

    If it's a FULL NA/Lower48 then it'll be too big to fit as I think you're correct saying that your 2720 is limited to ~1.7 GiB (that's Gibibytes i.e. binary, not Gigabytes i.e. decimal), so it should have ~1,825,360,000 Bytes probably. You can check the size of a region and dump its content using the method described in this [Only registered and activated users can see links. ].

    It's also possible to send an appropriately sized IMG as an RGN file using Updater.exe, as explained [Only registered and activated users can see links. ].

    Or you can use old programs like [Only registered and activated users can see links. ].

    So, there are several ways to load an IMG file to your SP provided space allows but none of them are as easy as using the PC Install files/GMAP folder. That's because you can simply select map tiles up to the appropriate size and transfer using MapSource or MapInstall, but you can't load an already-compiled IMG file that way.

    Note that whether using PC install or IMG transfer that the files must either be fully unlocked or you must embed a 25-character UNL code.

    Can offer any further advice on using this method? I was thinking Sendmap - and I tried working with it but was not able to create the install file to load the map into Mapsource. Or am I way off here....?
