In a previous century I was making raster GPS maps by processing scanned topo maps etc. with the help of OziExplorer.
Depending on a format of Garmin raster GPS maps, it should be possible to use a similar approach for any area without readily available electronic maps.

Yes and you know how hard and time consuming it is. I mean image processing and removing noise of a vectorized map is a great job. Colorado, Oregon and Dakota make it easy just to use a calibrated raster map and there is multiplicity limitation to use vector maps (I think at most 4 vMaps) but I didn't hear any limitation about number of KMZ using.
