Problem：How is the dynamic traffic information distributed, and how does the navigator receive it?
It is distributed through the signals sent by FM carrier waves, and navigator receives them via FM broadcasting automatically. Users do not have to intervene.
Problem：Is it charged to receive dynamic traffic information?
No extra charge is required at the moment. (Subject to the decision of end device manufacturers)
Problem：How is the accuracy of dynamic traffic information ensured if there is change of route information after the update of map on end devices? (We currently support four generations of maps, namely, 07W,
The FM-based dynamic traffic information service supports multiple versions of maps now. Reception of information will not be impacted after the update of map.
Problem：How do I know the timing of the real-time traffic information shown on the navigation devices?
It is marked on the timestamp below the RITC sign on the end device.
Problem：How is the dynamic information about parking spaces indicated on the devices?
indicates full availability with vacancy rate above 90%;
partial availability with vacancy rate between 70 and 90%;
occupied parking lot with vacancy rate below 70%;
parking lot closed;
situations in the parking lot unclear.
Problem：How is the dynamic information of parking space sent?
Transmission approaches like broadcasting and internet are employed to provide general and real-time dynamic information about parking space.
Problem：Where is dynamic parking space service available?
CenNavi currently provides such information in Shanghai.
Problem：How is event-based information displayed on the internet?
Problem：What categories does event information include?
It encompasses four categories: traffic restriction, traffic incident, construction work and road blockage.
Problem：Where is graphic traffic information product available?
Beijing and Shanghai for now.
