I am looking into purchasing a mobile GPS unit, and would love to hear other HTF members' experiences, good and bad, with different brands and models. I will be using the unit for long road trips, since my wife and I have decided to take more driving vs. flying vacations. This summer we plan to take a road trip to South Dakota (Badlands, Mount Rushmore, etc.), Montana (Glacier National Park), Alberta (Banff, Calgary) and return via the Canadian provinces. I am looking for something that provides automatic routing, voice command directions, and detailed information regarding points of interest in different areas (gas stations, hotels, restaurants, hospitals, police, etc.). I only need support for the U.S. and Canada for the near future, but the ability to add mapping for Europe at some point would be a benefit (but not an absolute requirement). So far, the Garmin StreetPilot III seems to best fit my needs. A co-worker highly recommends Garmin's products for features and manufacturer support. He is on his 2nd Garmin GPS, but his model and software are tailored for nautical and rural trail use (he owns a boat and snowmobile, and spends a lot of time on the Great Lakes and on backwoods snowmobile trails). A new StreetPilot III Deluxe version is available on June 3rd that includes just about every option I need for $780.
