I've written a little tutorial on how to install and use mmapper and sqlite3 for newbies (like myself). This is still a first draft so I would welcome suggestions and corrections.

The tutorial is at:

http://www.datasink.com/n800/mmapper.html

It also covers how to take existing waypoints that you have from some other gps and install them into the POI database.

I still want to add something on using flite and on planning routes.
