Time To Destination Algorithm
I have also seen MFN substantially underestimate the times it takes to travel. E.g. the following route in Colorado, USA http://osrm.at/80r, MFN estimates 33 minutes, where as the same route in OSRM (also using OSM data) gives an estimate of 52 minu…

External SD card not found
I might be able to confirm the issue with the advanced/settings/debug on stock galaxy S4. After installing 1.2.19 navigator still complained about only finding one SD card. Immediately after setting debug to high, it still didn't find the sd ca…

External SD card not found
This is effecting me too on a Samsung galaxy S4 after upgrading to Stock 4.4 KitKat. So I am looking forward to a fix and would be happy to try out a beta version. The version posted earlier in the thread by franc did not fix the issue in case it wa…

House numbers without addr:street and on relations?
snap to nearest road is definitely not always exact, but I would imagine that mappers mostly leave out addr:street if it is obvious to which street the house number belongs, i.e. if snap to nearest street should work correctly. So I would imagine th…

Unfortunately given the complexity of the boundary relations and the number of ways involved they are rather fragile and can break relatively easily. Could you add the relation numbers for the boundaries that aren't working? Also do you have a …

Thanks for the data report. I have gone through a whole bunch of them now and fixed some of them. In a good fraction of the cases, junction=roundabout was simply wrong. E.g. it was a long straight way that under no definition could be considered a r…

OK, sounds good. Perhaps one way to proceed would be that, (once done) you publish the full list of ways that were flagged as problematic by your converter. Which format probably doesn't matter for now, as long as it is reasonably easily human …

Whereas the first batch of issues reported in Florida where clear errors in the data and easy to fix, the second batch of issues in Germany don't seem to be as clear cut. In fact I am not sure if they are wrong at all, or if this is something t…

I have fixed the ways you mentioned for now, but that presumably is only a tiny fraction of ways effected. Interesting is that apart from the last way, non of the others were even close to being a roundabout. So I do wonder a little of how the junct…

Unfortunately there will always be some errors in the OSM data, that is simple the nature of crowd sourced data, so all applications will need to be robust to various strange taggings and mistakes. Everything (tagging) that can go wrong, probably is…

OSM and Navigator
An alternative navigation software based on OSM has created http://www.mapdust.com/ which is similar to OpenStreetBugs but optimised for reporting issues with navigation. In theory, this was really nicely thought out, as the software automatically r…

general bug and voice problem in navigation (free)
highway=road probably should be set to "Local Road" or "Small Local Road" and everything that is marked like that in the OpenStreetMap database fixed to have a more correct tagging. The highway=road tag was originally created for…

What is the difference between the free Navigator and Navigator (Paid)
What do you mean when saying "continues in navigation"? Mapfactor Free on Android showed a constant position on the map once the GPS fix was lost due to entering a tunnel. It did continue without problems once out of the tunnel again and t…

how to make turn lanes in osm appear in mapfactor free?
Way splitting might be a problem in general for routing and is becoming increasingly prevalent with the data complexity growing. Any property change (e.g. a change in speed limit or a cycle route splits off) requires a splitting of the way and start…

how to make turn lanes in osm appear in mapfactor free?
Nice! I tried it out in version 12.0.7 for windows. In simulation I successfully saw the lane assist when navigating down Glacisstrasse and it showed me the 4 lanes 1 left, two through and one right turn lane. However, when turning left or right at …

how to make turn lanes in osm appear in mapfactor free?
Great to hear the implementation of turn lane indication is progressing nicely in Mapfactor! One of the best ways to increase the usage of tagging in OSM, is to provide a good implementation of the tagging schema in a popular application. As it give…

Speed limit in miles per hour?
maxspeed is unfortunately one of those tags where people are a little inconsistent, so there are a number of different versions of non-numeric values. By far the most frequent is "maxspeed=XX mph" but without blank is common too and some p…

Speed limit in miles per hour?
It seems any road that is tagged with a maxspeed in miles per hour would be an example. But two random specific ones are: 1) Commercial Road in London, UK (OSM way: 3640469)2) Flagstaff Road in Colorado, USA (OSM way: 17021692)

I have tried both "Metric" and "US" settings. In neither was the speed limit shown.

street intersections vs street numbers
No doubt house numbers are much more useful than intersections, and mapfactor free does support them where data available. The problem likely, however, is that the underlying map data from OpenStreetMap used by the free version doesn't yet have…
