Garmin GPSIII Plus

The GPS III Plus has a 4 level LCD screen, which measures 2.2 x 1.5". Yes, it is small, but it is plenty to tell you everything you need to know in most cases.

The unit can handle 20 routes with up to 30 waypoints per route. This is usually more than enough, unless you plan on going around the world without ever archiving your GPS.

We mentioned earlier that the GPSIII Plus comes with maps already built in. Here's the scoop on the basemaps. The Americas Highway basemap includes, the United States, Alaska, Canada, Mexico, and Central and South America. The standard map coverage includes:

  • Oceans, rivers, and lakes (greater than 30sq. miles)
  • Principal cities and many smaller cities and towns
  • Major interstates and principal highways
  • Political boundaries (state and International borders).
  • Small lakes, major streams, and rivers
  • Principal urban areas (including AL and HI)
  • National and State level roads
  • Many local roads in or near urban areas
  • More detailed coastline
  • Airports
  • Database of exits for the Federal Interstate Highway System, including businesses withing about 1/4 mile of the exits, including restaurants, gas, hotels, RV parking, dumps, campgrounds, truckstops, medical facilities, shopping and outlet malls, ATMs and many more attractions.

That's quite a bit of stuff! If that's not enough for you, you can also upload additional information from a MapSource CD, including trip plans, topographical information, and more detailed maps.

When you turn on the unit for the first time, you will need to initialize the unit. This is a simple job and you can do it either automatically or you can use the direction button on the unit to guide the cursor to your approximate location.

The GPSIII Plus has six main pages or screens that are used during navigation. Pressing the PAGE or QUIT buttons will cycle through them. Here is a VERY brief overview that just barely touches on what these pages do. We have left out some functions to keep it simple.

  • Satellite Status: This shows you graphically, which satellites have been acquired by the unit and what their strength is. There is also a battery level indicator.
  • Position: This shows you where you are, numerically. A graphic compass display is at the top and shows you your direction of travel (track). Below, are six selectible data fields where you can display info such as speed, trip timer, sunrise, sunset, avg. speed, etc.. At the bottom, current position is listed in coordinates, current time and date.
  • Map: Always our favorite. Personally, I can't get enough of watching myself move around on a map. Garmin's GPSIII Plus is incredibly accurate. Any time I have zoomed in very close, I have always found myself to be right on top of a road. Rarely do I find the GPS showing me off the road (unless I really am). Maps can be easily zoomed in and out using the appropriately named IN and OUT buttons. You can also move around anywhere you like using the position buttons with your thumb. Moving the cursor around, you can see the coordinates change at the bottom of the screen. You can also see the distance to that point. By pressing the GOTO button, you set the map point as a waypoint and the GPS will guide you there. It will also draw a straight line to that point. You can set the Garmin to split the map display. A smaller section can then display up to four user-defined pieces of information, similar to on the Position screen. You can even set one to be an arrow which you can look at to find your way. You have your choice of scrolling modes on the map. One way is North Up and the other is Track Up.
  • Compass: This is just what it says. It's an electronic version of a hand-held compass. Like the other screens, this one can also display up to four user-defined pieces of information.
  • Highway: The highway screen is split three ways. The top shows a compass similar to the Position page. The right side displays the now-familiar, four user-defined sections. The main part shows a simulated highway. Imagine looking down a long road. Each waypoint along the way is displayed much like a road sign as you pass by. If you deviate from your path, the road will go off-screen and you will know to follow the arrow to get back on track.
  • Active Route: Shows the selected route if there is one, and includes Waypoints and Course.
