Toyota Motor Corp. and Fuji Heavy Industries Ltd. said Monday they have reached a basic agreement under which Fuji Heavy will install Toyota's G-Book wireless information terminals in its Subaru vehicles in Japan beginning in 2004.

The firms said they will use the G-Book as a common base for their respective "telematics" networks and information infrastructure standards.

The membership-based G-Book service allows drivers to access about 30 different interactive information services -- including navigation, e-commerce, news and weather info -- via wireless terminals placed in their vehicles.

In October, Toyota released the G-Book-equipped Will Cypha compact as the first model featuring the terminal as standard equipment.

Under the latest deal, Toyota will provide Fuji Heavy with information and telecommunications services, infrastructure and application technology necessary for the promotion of telematics service networks, the firms said.
