Low Cost GPS Receiver and Moving Map PC Software Reviewsby Joe Mehaffey and Jack YeazelRevised: 20 June, 2000 (Corrected for SA elimination and other details) Quoted prices are US$ COMMENTARY Some map programs have serious limitations: Street Atlas 7 has been greatly improved over SA6, but still cannot download routes from the Garmins with LINES drawn between routepoints. SA4/5/6/7 can show real time GPS tracks, but erase the track plot when the map re-centers. The ETAK System, and Precision Mapping 3 use a heading marker with only eight unique directions. Vista can display continuous real time tracks, but can't downloaded tracks, routes, or waypoints. PM3 insist on drawing lines between unrelated tracks downloaded from the Garmins. Garmin's MapSource CD ROM map systems can be used for uploading various maps INTO the G-III PLUS and StreetPilot, but have no capability for tracking progress on a laptop's screen. The Garmin G-III cannot simulate moving to a keyed-in position, although all other Garmins have this feature, making the unit not usable for evaluating map software function and accuracy. The Street Pilot cannot do point-to-point routing without outside help and is limited to 100 waypoints. For the record We have personally evaluated, to the best of our ability, all of the hardware and software mentioned, except as noted, and have no connection, financial or otherwise, to any of the manufacturers of the above hardware or software. If you have any comments, additions/corrections, or to request a review of your PC mapping software or hardware, please let us know via Email below or by fax: (770) 886-1767, (404) 255-5804.
