What's missing in Nokia OVI Maps for the Philippines are the POI or points of interest. After some searching I came across a Java based open source application than can run on any gadget that allows running Java apps including your PSP. The graphics is not as good as Nokia OVI Maps or Garmin Mobile but all the important and meaty guts are there - comprehensive POI all over the Philippines that's updated weekly thanks to Openstreetmaps.org, altitude, speed, compass, the ability to define roads & POI of uncharted areas, uploading to Openstreetmaps.org and voice navigation.

Driving along an uncharted area. So what do you do?
Well, be an explorer like Magellan and define the roads as you drive by. Upload it later to Openstreetmaps so others will benefit from your exploration.
