This entry essentially explains how to convert your bluetooth enabled smartphone into a GPS navigation system. This can also be used for those phones which have inbuilt GPS. If you do not have GPS, this will tell you how to store maps in your phone and view them.
1. Smartphone - any one of the following
(a) Nokia symbian 60 series or above eg. 6630, all N-series and E-series of mobile phones
(b) Any mobile running Windows Mobile 5 or 6.
Getting the right hardware:
If you already have a bluetooth GPS or an inbuilt GPS in your phone, skip to the next section. If you need a GPS navigation system, the simplest and cheapest way I think would be to buy a smartphone and a bluetooth GPS and get it for half the price of a phone with inbuilt GPS. For instance, the cheapest option that I know of is Nokia N72 (INR 8000/-) + Navibe GB735 (INR 1800/-), while most of the GPS enabled phones currently in the market are above INR 20,000/- . There are Nokia smartpones cheaper than N72, but I they are much less worth for the 1000 rupee less that you pay.
Getting the right software:
(a) If you are using Nokia phone, get the SmartcomGPS software. You can get it from here mobilesmania forum. You will need to register for free at the site and dig a little bit to find the version for your phone. There is also a older but less featured MapViewGPS. Any of the above software will suffice.
(b)If you are running Windows Mobile phone, get the OziExplorerCE software, which is also available at the mobilesmania forum
Getting the maps
(a) If you are using Nokia phone, convert any of map image(JPG/PNG/BMP etc) that you have to ogf2 format using this software.
(b) If you are using Windows Mobile, use the Img2ozf application which come along witht he application to convert your files into the ozf2 format
(c) If you are using GPS, you need to calibrate the maps before you first use it. (i.e generating the .map file)
For your convenience, I have given links to some of JPG/PNG maps here. Below are the OGF2 and MAP files for some of these maps. You can store these files directly in the "e:\data\smartcomgps\maps" folder of your phone and get it working right away with or without GPS.
