Navigation system for Taxis

I took a taxi today. I asked to go to Fook Hai Building. The taxi driver did not know the way.

I suggest that each taxi should be installed with a navigation system. The taxi driver can enter the building or road name or the postal code. The navigation system will give directions to the taxi driver.

There is no need for the taxi drivers to know all the roads and buildings (which will be a difficult task) or to refer to the directory (and still not know the way to get there).
