[mkgmap-dev] Problems searching for California addresses

Sat Mar 3 05:51:45 GMT 2012

Hello Bill,

some of the problems are caused by the fact that you use the california.o5m
to create the 
bounds for california. This extract probably doesn't contain any usable
information about admin_level=2 boundaries like "USA".
You should either use a larger extract (e.g. north america)  to create the
bounds or download
the precompiled boundaries created by WanMil:

http://www.navmaps.eu/wanmil/

Please try that first.
