I've tried now with r942 on a etrex and seen the following:

Crossing S/N borders seems to be no problem, routing gives more or less 
reasonable routes.

Crossing E/W borders doesn't work ok, as described by others too. In my 
case it alway finds a route, but the route is really not optimal. The 
inter tile crossing always takes place at a highway or a secondary one, 
even if start and destination are only a few kilometers appart and far 
from a highway.

My impression is, that routing on E/W borders doesn't work at all, but 
takes place at the basemap instead.

I've verified with two different start/destination pairs. Crossing 
borders in E/W takes only place, if roads in the basemap are available.
