I made a route with Base Camp: 154 miles with origin, 7 shaping points and the destination. I connected my 595 to my compter, waited on Express, yada yada. Using Base Camp I drag & dropped my new route to my SD card. I disconnected the 595 and turned it on. I imported the route & a preview showed exactly the route I made. When I chose Where To/Trip Planner/My Route Name
, I was given 2 choices- the origin or the final destination. Since I was sitting in the parking lot of the origin, I picked the final destination.
Amazingly the 595 followed my route perfectly, even the recalculations when I A) voluntarily didn't turn and B) involuntarily missed a turn. Never a missed beat. Go figure.
I know that it is a while ago, but though i would post the answer to this little conundrum.
1. Using BaseCamp to devise a route is the best way to plan your route in my opinion. You have a start, an end, and 7 shaping points.
Comment. Shaping points are useful, but they never appear in the list of possible choices of next destination when you hit GO. If you have the data display showing, you cannot display 'time to' or 'distance to' a shaping point. Shaping points never alert you as you approach or arrive. If you miss a shaping point but pick up the plotted magenta route after the point, the Zumo will continue navigation to the next shaping point without nagging you to go back to the missed point. All of which may be exactly what you want.
2. You imported the route to the Zumo and it showed exactly the route that you had plotted.
Comment. Brilliant - this is what Basecamp does better than any other routing software - if you have the same version of maps on your PC and the Zumo. It does this by sending hundreds of invisible intermediate points (I call them ghost points) to the Zumo. The Zumo plays 'join the dots' to recreate the original route precisely as it was in Basecamp. There is a slight issue with these - if the Zumo has to recalculate the route eg if you deviate slightly - then the ghost points are lost up to the next shaping or via point - leaving the Zumo to work out its own route for the current section. But that is what satnavs do, if you deviate.
3. You started the route and were presented with two choices, as to where to go next. You selected your end point as the next destination.
Comment. This is the most common error with Trip Planner. The choices only show via points and start and end points, not any of your shaping points. If you select the end point, what the Zumo does is ignores any routing up to the chosen point and makes its own mind up about how to get there. It is entirely possible that it will follow a completely different route from the route it received from BC.
4. It took you along exactly the route you had plotted.
Comment. That really was Sheer good luck ! There can't have been any alternatives, because selecting the end point tells the Zumo to get you there however it likes - using the transportation mode and preferences that it has set up for the cradle that it is in. Correction. I missed the fact that you had deviated. What is happening is that in effect the satnav is not following a route at all. It is just getting you to the point you selected - the end point, recalculating at each variation from what it has worked out.
What you should have done is selected the start point as your next destination after pressing GO. However, this presents a practical problem because you may be just a few tens of metres along your route, beyond your plotted start point. The satnav will have you going back to it ! In this case, pressing Skip will make the satnav work out its own route to your next Shaping point, and then follow your planned route from there.
A much better solution is to always make the route on your map start some way up the road from where you will actually start. Eg, if you are in a town overnight, have your start point on the first road that you will travel after leaving the town - eg beyond the ring road, perhaps. Select that as your start point having pressed GO. Zumo will take you to it the best way that it can, and if necessary it will work out a new route if you are diverted in the town. But it will get you to your start point and then continue on your planned route, one shaping point ( or via point) at a time. Much better.
