The trick that is working great for me particularly is mentioned here. I have a SonyErricson K790i with J2ME. So I installed mgmaps on it. Then came creating an offline cache so that it does not need to download each and every time as I move my GPS along the undocumented roads. To create cache I select zoom 0-17, use Openstreetmap (Maplink) renderer. After cache map is created using the creator tool, I download all the OSM tiles using the gMapMaker which can read and create full offline cache directory structure for mGMaps. Thats the homew0rk part of it.

Now as I go along GPS Tracing using my Holux m241, I keep checking ways on the already OSM tile on mgmaps. As long as I can’t find a way on screen, I going the right way!.  The target is to hunt unmapped way therefore have the marked ways with you and do the turns which are missing.

Later in the evening, I load the GPX file itself and then download the OSM data for that zoom level. Now I have partly marked ways partly just GPX lines. Which I convert to real ways and name them as much I can. The other problem of Gurgaon, HY, India is that we have not named our streets, therefore most often, the names are either guess work of just human readable rather than in sync with the policatal/official data.

The modes of transportis either a bycycle(almost like this model) or my classic Kinetic Honda (which is no longer manufactured) and m241 set of 1sec log autolog mode.
