"I have used Streets & Trips 2009 in Mexico a lot. I've used it in the
following states: Tamaulipas, Veracruz, Coahuila, Chihuahua, Sonora,
Sinaloa, and Durango. Generally I'd say it has very good coverage from major
roads down to small pueblos.

Perhaps the biggest limitation is when you try to map along the autopistas,
especially the newer ones. For instance, you can't map a trip from Tampico
to Veracruz using the autopista from south of Tuxpan, then bypassing Poxa
Rica/Papantla (180D, I think). Of course, this is a common problem for all
Mexico maps; the latest Guia Roji atlas doesn't show some autopistas that
have been done for years (Ojinaga to Aldama, for instance)."
