Files are created from UMP data. They contain speed cameras, black spots and railway crossings. Points are sorted by speed and provided with appropriate icons.
Files with number "22" in name contain small icons, designed for use in standard nuvi with screen size 480x272 or 320x240 pixels, like for example nuvi series 2xx, 7xx, 1xxx, 2xxx.
Files with number "44" contain big icons, designed for nuvi with higher resolution screens, like models 3xxx.
