GPS Navigation System [merged threads]

[woohoo]

been using my garmin 255w. ok nman yun 2 phil map na naka load. i use osm for MM and phil roadguide pag outside MM.

Ano yung OSM, sir? How do you switch maps? Thru the renaming method (gmapsupp.img)?

edit: after a quick google search, i found OpenStreetMap (OSM)

Hmmm... I wonder if OSM and roadguide.ph are open to the idea of importing from each other's maps? (or is it sacrilege for them? ) I was surprised to find that OSM seems to have more detail.
