The application will help Dialog Subscribers find direction, plot routes and find places of interest, a statement said.
The Dialog SatNav system has voice support navigation in Sinhala, Tamil and English languages allowing drivers to navigate their vehicle without looking at the screen of the navigation device.
The system has a detailed map of the island's road network, which includes small city streets.
In addition, over 100,000 points of interest such as places of worship, tourist destinations, financial institutions, automotive repair, emergency services, medical services and restaurants are pre-loaded onto the device, available on demand.
The system is based on the network of radio navigation system satellites known as the Global Positioning System.
"With the rapid expansion of highways and the rural road network in post-conflict Sri Lanka, emerging technologies like SatNav will offer hassle free motoring for Dialog subscribers, Supun Weerasinghe, Group Chief Operating
