A route in the context of consumer GPS is a serie of via/way points. When you have loaded a route on your GPS it is up to the GPS to select roads from one via point to next. The way your GPS takes you from point to point depends on settings and map used in your GPS. The same route loaded on two different GPS units can therefore be different. Both GPS units will take you through the same via points defined in the route however. To avoid differences from GPS to GPS you use many via points. Routes are best stored in a generic format called GPX (GPS exchange) because it is readable by most GPS models. A single GPX file can contain several routes ,tracks and POIs but this simple online tool only works with one route per GPX file.
Double click on the map where you want your route to start. A green marker will appear on that point. Double click again on the map where you want your route to end. A red marker will appear on that point. Now you have a simple route already. You can name your route by clicking on the banner in the upper right corner. To add via points you double click where you want them to be. You can adjust the positions of the markers by drag-and-drop. If a via point would be given wrong order number you click on the marker and then adjust the order number by clicking on the arrows in the pop-up window. You can delete a point by clicking on it and then click on the trash can in the pop-up window. You can name a point by clicking on it and then type in a name in the form and click on the save button or press enter.
Dual Carriage Ways
If you place a via point on the wrong side of a dual carriageway the GPS will ask you to make an un-wanted U-turn, go back and then an other U-turn.
Marker on the wrong side.
If you place a via point close before an intersection where you intend to turn you may miss that turn. This is because the GPS, depending on model, will not announce the turn until you have passed the via point in front of the turn. Therefore it is better to place the via point after the intersection.
The turn is not announed because it is hidden behind the via point.
The turn is clear.
Close to Bigger Roads
If you wish to drive on a road that runs in the same direction as a close by bigger road you should place extra via points to prevent the GPS from jumping out to the bigger road.
Informational Via Points
Via points can also be used to notify about upcoming places like rest areas etc.
You reverse a route by clicking the reverse button. After doing so you need to check the placement of your via points. Some via points can be on the wrong side of dual carriageways and close before intersections.
The easiest way to load a route on a GPS is to copy the GPX file direct to the GPS like you do with a USB memory. Connect the GPS to your computer with a USB cable.
Place the GPX file in the internal memory in the garmin/gpx folder. Older models will ask you if you want to import it when you turn the GPS on. Newer models will import without asking.
Place the GPX file in the gpx2itn folder.
