Hi Peter,

I've been a few days searching and testing something that I haven't fixed yet. In my app, i create an itinerary file, load it into tomtom through the LoadItinerary method. This loads the itinerary fine, and if i go to the menu (in tomtom navigator) to the itinerary section, I find all the addresses I put in my file. But when I call the NavigateToNextStopover method, it just does nothing. I want to start the navigation to the first stop of the itinerary. What I'm I doing wrong?

And by the way, if i have for example 5 or 10 adresses in the itinerary, is there a way to have tomtom reorganize them to drive the optimal route?

Thanks in advance,

Santi

How was the itinerary file created? You have read about the different types of point in a waypoint file - the item must have flags = 2 to be marked as a stopover point rather than a pass-through destination.

Unfortunately it is not possible to programmatically optimise the order of the route.

The file is created in my app. I didn't find any info on .itn files structure, so i created some of them through tomtom navigator and investigated the structure. The last field of every line is this flag you mention. I saw that the values go like this: 0 = Pass-through Waypoint; 1 = Visited Waypoint; 2 = Destination.

I've tried with all addresses as waypoints but the last one (Destination) and all of them as desination. The navigatetonextstopover does nothing in both cases.

 This is an example of the last 3 lines of one of my files:

219362|4138354|menorca 7, BARCELONA|0|
219292|4141493|huelva 18, BARCELONA|0|
221019|4140463|fluvia 15, BARCELONA|2|

 Is this all right? For what i've seen in the files generated from navigator i think so.

And by the way, what's the difference between a pass-through waypoint and a destination address? Navigator will notify "arrived to destination" only if it's marked as Destination or something like that?

Thanks

Items marked with the stopover flag are points at which the route can be stopped at whereas a regular waypoint (0) will be passed through with continuous navigation to the next point. Therefore if your itinerary contains multiple distinct stopovers you would use:-

219362|4138354|menorca 7, BARCELONA|2|
219292|4141493|huelva 18, BARCELONA|2|
221019|4140463|fluvia 15, BARCELONA|2|

Ok, that's what I thought. But the NavigateToNextStopover method still does nothing, and i'm not sure if this is the right method to call or it's another one. Thanks for the info.
