I did some exploration and discovered this (maybe well known but not by me):</span></p>

With a lot of cross-model experimentation I discovered a single POI code (0x1E00) will display large text on all garmin models I was able to test with (Montana 6XX and 7XX, XT, XT2, Tread). I have no idea if this POI code will work with all garmins that support custom maps.</span></p></li>

I presume that an OSM map generated for an area works on all garmin devices? I will admit that I don't know what the OSM map limitations are across garmin models. Does the JOSN model allow the devices POI maps to be loaded on a per-map basis? If I were to switch to JOSN model for mkgmap input, could I get around all the device limitations I am running into with the mp file format? Can someone recommend a good tutorial on getting up to speed on generating JOSN for simple map input to mkgmap?</span></p></li>
