briansue : Sorry to hear that MS is not continuing with Streets and Maps. It has proven very good through Yucatan. It does not go into Belize. Keelhauler showed us how to customize which proved helpful (forgot how at the momennt). The Garmin works well into Belize and Guatemala (the highways are not exact in Belize). Generally have liked to go over the red Mexican atlas and S&M the night before traveling and making sure the GPS doesn't take us to "roads not traveled and there are good reasons why they are not!" As the old saying goes, "there are places unknown since those that went there have not returned!"
Will go through web sites you provided. Thanks
