Route66, GPS road navigation system, the largest mobile phone software I used

Route66 V7 for s60 V3, a road navigation system with GPS positioning function, the program file itself is about 15 MB, its traffic map data file is up to 216 MB only in mainland China (this is a separate file, China. PRM contains traffic map data of 314 major cities in China. In addition, it also downloads data files from Hong Kong, Macao and Taiwan (but these three locations are less than 10 MB in total ), of course, there should also be data files in Europe and America. We will not download them, but there is no chance of driving in the past, haha.

The program is big, but it is not slow to start and runs smoothly. Search for a street name nationwide and the results will be returned in two or three seconds. After a start and stop location is specified, female voices can tell you whether to turn left or right at any time in Chinese, and various information (gas stations, shopping malls, meals, traffic lights, and so on ). Not only is the running speed not slow, but it does not occupy much memory. It takes only 3.65 MB to use taskman. I usually write some programs and have a basic understanding of mobile phone programming, but I still cannot figure out how it handles this huge M data file, taking into account both memory usage and running speed.

I was amazed at the "big" of this program because the Nokia 3100 (s40 series) I used previously only allowed a maximum of 64 K programs. 64 K or less, more than m, the comparison is not strong.

The following figure shows the running interface of route66 in my Nokia E60:
