Out of curiosity have you tried using a different, fat32 formatted card with the Garmin>Maps folder setup
I'm curious if this Hawaii the "Windows" version if you copy the .img to the Garmin/Maps folder, copy directly if you can and it is small. I "created" my maps to be as universal as possible.
As far as USGS maps, Orux (Android only) will display geopdf's that you can get from the usfs and usgs national map, and maybe a few other places.
I'm fairly new, the past 4-5 years, to map making. There are a fair amount of downloads, so reported problems have usually been solved. I'm curious to how this turns out
