Just responding to the post #23. ST1100Y and Mellow. Hopefully to add a little clarity. It wont let me quote the full message with the quoted sections so I've reproduced it .
Exchange 1. There seems to be a misunderstanding here:
The previous 595 I had worked great, if you missed a turn and passed a waypoint that was say 1 mile away but then came near a road which put you back on your route it would continue forward and ignore the waypoint you missed .
The principle enabling standard situations while on a tour, like stopping for food, fuel, visiting an attraction, having to follow a detour due to roadworks/a procession/a festival, etc...
All Zumos that use the trip planner app include the faciity to add two different types of route point:
Via points which alert on approach and arrival (orange flag)
Shaping points which do not alert. (blue or orange disc)
If you miss out either of the points the Zumo will attempt to navigate you so that you visit it. Always.
If you reach the plotted magenta line after missing a shaping point, the Zumo will continue to navigate ahead and will stop its attempts to visit it.
If you join the magenta route after missing a Via Point, the Zumo will continue to navigate you to the missed Via Point. Forever. There is no way out of this except by using the Skip Feature or restarting the route.
This was true for the 590 and 595. The XT behaves in exactly the same way.
(The 590 had a skip button, the 595 had an edit route button which allowed a choice of skipping the next via or next shaping point. The XT had both)
Exchange 2 is similar
The XT will keep trying to route you back to that missed waypoint so you have to click the skip waypoint to continue on your route.
hence impeding any normal regular usage mentioned above...
As above, the XT is no different from the 590,595,660 and 550 in this respect.
But there are 2 different types of point that are used to form a route. Any route point has to be set as either a via or a shaping and it is these behave differently when missed.
Exchange 3
As stated in this thread, that is for a route you created on basecamp and then imported into the XT. If you built the route on the XT manually, it works like the 595 does
This "stand alone" design is again impeding usage as designated motorcycle navigation assistant...
The XT behaves like the 595 does anyway. This RUT behaviour only happens on the XT if it is forced to recalculate the route eg after pressing Skip.
The issue isn't confined to Basecamp routes. Any file created on any mapping program that puts a gpx file on the Zumo will be treated as imported, and will display RUT behaviour in the same circumstances.
Fooling the XT into believing the route is Saved rather than imported, makes any route behave as if it was built on the XT itself. I have tried, but every 'saved' route has never displayed the RUT behaviour. Same route, identical route points, same test, same deviation. The imported route gets stuck in a RUT loop, the saved version does not.
The fix is easy as shown in the video. Just load any route, say Go, then in trip planner Save the active route. Use the Saved version.
