Garmin's ColorMap StreetPilot III Garmin Garmin's ColorMap StreetPilot III is Garmin's first receiver with automatic address to address routing. It also has voice command output. StreetPilot III coupled with Garmin's CityNavigator mapping program delivers one of the most detailed street maps available on the market. Users can load detailed maps for one or more of 120 US cities. These are not included with StreetPilot II. These detailed maps are also supplemented with a feature called "base maps" that are included in the system. These two types of maps let a user plot routes from one city to another without loading all of the maps in between. The price for StreetPilot III is $850, on of the lowest priced Automatic Car Navigators available. Colormap StreetPilot III is designed to combine a GPS receiver, a laptop, and map software into one system. For additional memory, you can add 8, 16, 32, 64, and 128 megabyte memory cartridges. Most city maps are between 500k and 2mb of memory. The auctomaitc address to address routing requires the CityNavigator map offering in order to work effectively. The routes that the StreetPilot III chooses are usually the best routes, but again it is difficult for the machine to take into consideration other factors that might affect travel. Address to Address route generation is really fast. It can take anywhere from 30 seconds for a local route to 2 minutes for a national route. Since this unit is larger and designed for automobile or street use, the battery life is somewhat low. It lasts around two hours before it needs to be recharged. All and all, for a price of $850, StreetPilot III is an excellent value and provides cutting edge features at a reasonable price.
