Most likely, you don't want your devices to know anything about the
API. You just use the API (or some other way) to get the data in XML
form, and you'll probably want to convert this to some format more
suited to your devices -- perhaps something like http://wiki.openstreetmap.org/wiki/OSM_Binary_Format
. I also suggest to check out how some of the existing routing
applications store their data.
