Navigasi.net has got 209 MB, Garmin 2012.10 is only 100 MB. Navigasi covers most parts of Indonesia, Garmin only Jawa and Bali and the main roads of Sumatra. Navigasi shows much more details, for example different stations of a hospital in Solo or the buildings of the University, at Garmin there are a lot of islands without any coverage. Navigasi is up-to-date because there is an update every 2 month, posted by people who really live in Indonesia. POI like restaurants, hotels enter the map through recommendation of the users and not through payment. Garmin only updates 2-3 times yearly. Navigasi is free but even if it would ask for the double price as Garmin it would be the much better choice.
