Copied from another thread.
I have been enjoying and experimenting with my android phone and acer tablet.
Three of my favourite vector mapping apps now support non NT Garmin Maps. There are probably others.
Navitel Navitgator - some conversion required.
Osmand+ - some conversion required.
Now the WINNER:
OruxMaps is available as a free or paid (cuppla dollars) app.
The latest version directly supports mapsets copied either directly or via Garmin MapSource or BaseCamp.
Free OSM mapsets also available:
Tested with ShonkyMaps, OzTopo and many others.
