Unfortunately Mapfactor still doesn't follow our requests for traffic lights in their maps.
To overcome this "issue" I rewrote my python script to create "traffic lights" maps as POI maps for you.
The python script is now written for windows. It downloads the "full pbf format" countries, it extracts the necessary data, and it creates the mca file for you using DiggerConsole: all automatically.
If you are lazy then download the "TrafficLights" zip for your region, unzip it and copy the countries of your liking into the /Android/data/com.mapfactor.navigator/files/navigator/data folder where all the other maps are also located.
From another lazy one, I've done all you say, and extracted the relevant .mca file to the data directory. How do I make traffic lights appear? I thought they would be in one of the poi categories, but no luck.
Note that "traffic light" density as registered in OpenStreetmap varies hugely per country.
the Netherlands have a very good coverage, but even Germany has not so good coverage and also varying per city (Based on your name I assume you are not German though ;) ).
Some countries have hardly any traffic lights/signs registered in OSM.
Please take a look on openstreetmap to see whther the traffic lights you are expecting are indeed in Openstreetmap.
And of course: For which country did you try the mca? There could be an isue with the file.
And the data folder: Did it already contain mca files for your countries? Note that there are 2 data folders: one on your internal memory and one on your SD-card. Whether they are used ornot. Copy the mca files in the correct "filled" one.
I'm in the UK. The map is the OSM one for UK. The traffic light file is for Great Britain. I'm looking where I know there are traffic lights on the OSM map. The MCA file is with my map file in the data directory.
@tomas: What do you mean with show on map? I did not need to activate anything. To make sure I disabled all POIs and restarted Navigator and they still show on the map.
If you look at the picture of my other post about day/night colors you can see the traffic lights in the night screen capture.
But slightly further in the street (nr 24 or 16), crossroads Unter den Linden with Friedrichstrasse, the traffic lights are not displayed but they are available in the gpx and in the (unpacked) mca.
also, when slightly following Friedrichstrasse up north they are available on the next crossroads (Georgenstrasse).
But: Detmold, Bielefelderstrasse 12 (crossroads) does have a traffic light in OSM (modified 2014-05-17 by chattiewoman) but that one is NOT in my gpx/mca.
Really strange: it seems like issuess with my file(s) and issues with navigon.
I will check my script and keep all intermediate files to check.
(Note: I don't see a difference either in software or hardware renderer.)
OK, I can see a traffic light at the Hereford intersection but not others more locally that I know are in the OSM data. Also, the OSM data has multiple signals at the Hereford junction but only one is displayed in Navigator.
