Hi Guys, mainly THANKS Tommi! - looks you're on a good way to solve this, but "bad luck" happen

OK, so please ketani. If there is any problem, we need from you better description of this. What are you exactly doing, step by step ...
to start from somewhere, try this ...
1. read this
http://docs.locusmap.eu/doku.php/manual ... te_measure , mainly feature of button 5!
2. start menu > functions > Add new route & measure
3. press button 5
4. on new dialog, press top settings button and also check that you have source for navigation MapQuest or CloudMade!! (important)
5. select some method for example fast car
6. then add on map few (at least two) points by moving map and pressing first button
7. in final, you should see purple base line between your points and blue curve computed from online service between your points
8. press button 7 and then OK to store this route to database
this is complex method how to precisely create route for navigation. Is this working for you? If so and you have such route on map, tap on it and from one of bottom menu select "Navigate"
if any step don't work for you, describe it. This is anyway just method how to create route that may speak. If this will work, next step will be to check if your voice works correctly ...
