Thats Electronics Toll Collection system it works only in JAPAN not in pak,
"ETC" stands for Electronic Toll Collection. Its a system which basically deducts money from your card automatically when you pass a toll gate. If you don't have one of these, you have to stop and physically pay some guy/gal before you can pass - if you do then the gates will detect the unit and open automatically. As soon as you pass, the unit will speak out how much it cost to pass through the toll gates.
VICS stands for Vehicle Information and Communication System - a system that transmits info of any traffic jams, road accidents or mountain slides to your Carnavi. Roads which are blocked will show up as red. If there are accidents, the Carnavi will warn you and attempt to redirect you.
