Thanks for your observations.

I'll be checking with them if they can perhaps publish both raw OSM
data and a version with OSM data alone that the device can read. (I'm
not sure how that encryption works.  For example if each layer was a
separate file and the files were encrypted individually then it
shouldn't be hard to do)

However... the second piece you quote kind of makes it difficult to
make use of section 4.7b that you quote first.  Except in the cases
where anyone can produce that Restricted Database from the original
database and I imagine normally that's not the case. (?)
