GPS Navigator with HERE, OSM and other mapsCityGuide - the new-generation offline GPS navigator, which enables you to select and use maps from various map vendors: OSM (OpenStreetMap), the project that creates and distributes free geographic data for the world. CityGuide maps based on OSM data offer worldwide coverage and stable updates. HERE (NOKIA) maps, a high quality paid-for maps collection. CityGuide maps, with traffic information and regular updates. Other high quality maps from national map producersMaps have various prices, conditions of use and update frequency. You select the maps you require from within the CityGuide application. Each map has a short description and a star rating, and a trial period is available. CityGuide is an OFFLINE navigation system, which does not require a permanent internet connection. Selected map data is downloaded to your device, so you do not need to be connected to the internet during use, thus significantly reducing costs. Other CityGuide advantages: Smooth operation and rapid route calculationFull support for built-in hardware acceleration on most devices. Rapid map manipulation. Instant route calculation, using traffic information where available. Daily maps updates (online proofing) No need to wait until next major map update. Changes in road conditions on maps (e. g. closed roads, no traffic, one-way, turn restrictions, and more) are sent to the map daily and used during route calculation. Patented method of route calculation uses traffic informationWhen calculating a route, CityGuide uses our patented algorithm 'Jams-2', which takes into account direction of movement and traffic speeds. If traffic data is not available, statistical data is used instead. Dynamic Points of Interest (POI) provide warnings of current road eventsCityGuide users are warned, by voice and visually, about various current events along the route (police, danger area, speedcams, traffic accidents, bad roads, traffic jams, etc. ). Speedcams and speed radarsCityGuide provides advance warning of known stationary and portable speedcams.
