No such thing! Very valid questions.
1) You can put any maps (*.fbl files) in your ..content/map folder that you intend to use..now or in the future. If you are physically in the area of the map..with a lock on satellites..the maps will automatically be used and displayed. No need to 'switch'.
The only thing you can't do (for example) is to route from the UK to another country if the country maps
in between are not present.
2) You should be OK. All maps should work...this depends on exactly what you downloaded from where, of course.
To check this, install the maps, go in settings to Help>About>More>Content, etc..... if the maps are enabled (or not) it will show as such.
