Satellite Navigation, Tom Tom Custom Sounds So you have been warned that tomtom will not give any support if you add a custom POI and associated files. So lets take a look at the 3 files needed for a custom point of interest;
The .ovr file is the file that contains the actual locations, using tesco.ovr as an example one of the locations may look like this; "Tesco - Penzance - Branwell Lane","Tesco - Penzance - Branwell Lane",-5.52470,50.12728 As you can see, it has the name of the store, and at the end the gps position in latitude and longitude. These are plain text files, and are not the same as the encoded files used by the tomtom, for example, tomtom's own POI's like beaches. Next is the "tesco.bmp" just a small bitmap picture that will display on the tomtom's screen when a POI warning is given. Lastly we have the "tesco.ogg" which is the ogg vorbis compressed audio file |
