I'm away om jollies at the moment and have a route planned for each day using shaping points.
A few days now the Nav V has taken me a different route.
For instance route set out of Bolzano over Gavia pass to Bormio, Nav V took us from Bolzano to Merano then over Stelvio form the north into Bormio. Stelvio was supposed to be today!....Any ideas?
I think I may have worked it out; here goes:
You wanted to go: Bolzano over Gavia pass to Bormio and plotted a route at home that went that way, putting in shaping points to route you over the Gavia pass.
You loaded the route into device and on the day of your journey you ran it
Your device altered your route to go: Bolzano to Merano then over Stelvio from the north into Bormio. This missed out the Gavia pass which is south of the Stelvio. This is the most direct route between Bolzano and Bormio.
Do I have that right? If so, I think it's probably down to operator error mixed with the way the Navigator V's much more advanced navigation and route calculation features work.
I think your device will have displayed the route you plotted correctly, right up to the point you pushed GO. When you pushed GO, it's the moment things probably went wrong.
I think you were not at your pre-planned start point when you started out. So, when the next screen gave you the choice of two - or maybe more - destinations (your start point at Bolzano and your end point of Bormio and any additional intermediate waypoints you might have added) you chose Bormio. As you were not at your start point, the device did
exactly what you asked it to do.... It took you
from where you happened to be to Bormio via the fastest route it could find.
This overwrites the planned route you had created. Had you selected your Bolzano start point as as your destination, your device would have recalculated your route only very slightly and according to the preferences you have set up in your device *; in short, it would have taken you
from where you happened to be to your Bolzano start point and then picked up your route, over the Gavia pass and on into Bormio.
If I have all this correct, just take a bit of care as to how you operate your device; it really is much more advanced than you might think and streets ahead of earlier models like the 660. Then all should be well. Similarly, get used to looking at your direction of travel on the compass. If you are heading north for a long time when you are sure that your broad direction of travel should be west, then you should know that something is not right. In other words, do not follow your GPS device blindly... Particularly if it is taking you down roads you really did not want to follow. Your pre-planned route via the Gavia pass was on a totally different compass setting than the Stelvio route.... Heed the warning signs. If you want to be heading south, the sun should be near enough in front of you for much of the day. If it's behind you, there is a good chance you are going north. Stop and check and take a map!
* The preferences setting is really important. It's something many people forget about, setting it once and then never looking at it again. If I had a pound for every routing problem I have fixed by reminding bods that if they have set their preference to be always avoiding motorways and to always take windy roads, then there is a very good chance it will not take the M1 between London and Northamton, no matter how much they curse and swear, I'd now be long retired.
PS It is not entirely true that the Nav V will always route you through waypoints. In choosing Bormio from the choices of destinations you were probably confronted with, you (and not the device) instructed the Nav V to ignore your pre-planned route - and all its carefully prepared shaping or waypoints - instead, asking it to take you straight to Bormio according to your pre-set preferences. Had you been on your route properly, then (and only then) would the device have insisted that you go through the waypoints. Get used to how the Nav V works, looking at the route it offers up, learning how to use the skip function and a load of other features. It really is very good but it's far ahead of earlier devices, so it takes a bit of learning... That learning sometimes starts with how your create routes on your computer at home in the first place.
Hopefully, this has answered your question and the rest of your holiday will go swimmingly well.

worth reading for a simple explanation on Via pts and shaping points etc.
