Enable Sri Lanka GPS navigation on your Nokia device

There are so many GPS enabled mobile devices coming to Sri Lanka but unfortunately Nokia doesn't provide the map of SL at there OVI store. Last week I got some time to play with my Nokia 5800 and thought to find someway to install an offline map works in SL. First I installed Google maps but unfortunately it doesn't work offline on Symbian OSes. (It says it works on Android). After few more tryouts I could find some posts regarding Garmin XT on mobile devices and finally it worked.

So below this post actually not something I invented but provide A to Z guidance to install SL map on your Nokia device without browsing so many posts, articles and wasting time. 

Download file contains

1. Setting up Apparatus, The Nokia 5800

1. Back up all data using PC Suite (go to Nokia website).
2. Soft reset by pressing *#7370#. Should take about 2-3 mins and you lose all your data (except on memory card). But don’t worry, you have back up remember?
3. On your Nokia 5800, go to Application > Location > Positioning > Positioning Methods. Enable “Assisted GPS” and “Integrated GPS” ONLY. This will ensure you don’t get charge using WAP or 3G network for Internet.
4. Go to Application > Location > GPS Data > Position > Options > Satellite status. This will show the satellite signals you’re receiving. Be sure you are outdoor in an open area. Balcony doesn’t work well, believe me I’ve tried. Once you’ve got AT LEAST 4 satellite signal, go back indoor, you don’t want people to think you’re crazy, waving your phone around.
5. Now you’re ready for GarminXT.
