Toyota will offer a car navigation service for smartphone users starting today in Japan. The ‘‘Smart G-Book’’ service will require subscribers to load their smartphones with special application software which would allow them to have directions to their destinations set up on their phone display by calling a telephone operator and saying where they want to go, according to Toyota. Available for 900 yen ($10.70) for six months, the new service will start with smartphones based on Google Android operating system and will become usable on Apples iPhones later in December.
