XT2: Section 5 - What Goes Wrong

5.01 - Routes from GPX Files

The Test Route

The image shows a route that consists of 8 route points. It is heading south to north on the A6 and the route points have all been given easily to recognise names :

01 Start, 02 Hollins Lane, 03 A6 - - - up to 08 End M6. The name is not important, but the presence of the leading number is significant - as it will make it easy to spot if the XT2 has changed the name of the route point.

The route points are shown as large blue circles, and they are placed in such a way that the XT2 should not route me onto the nearby motorway - the M6. So the planned route bstarts at the bottom of the map with point 01 to point 07 near to the top. Point 08 is actually on the M6 because I want to by-pass Carlisle. Between points 04 and 06 the M6 and the A6 run very close to each other and cross over each other a few times.

There are times when importing GPX files results in behaviour that I would do not want. For example - it sometimes moves route points and places the route on different roads. This exercise is to give a demonstration of that behaviour and try to pin point when it happens.

You may have noticed that I have mentioned only ‘route points’. That is quite deliberate, because at the moment, the type of route point doesn’t matter. But I will be using the terms Via Point, Shaping Point, and Waypoint in the way that Garmin use them. If you have learned Zumo stuff from Facebook or other routing programs, then your understanding of these terms will probably not be the same as Garmin’s.

eg A Via Point is not the same thing as a Waypoint. A Waypoint is not simply a point on a route. Not for Garmin, not for the GPX file standard. If those two statements alarm you, then you may want to take a look at this page to get a better understanding, because this won't make much sense unless we are speaking the same language !
