Onboard information service "TelematicsService" was started by the auto giants in 2002, up to now about six years. But communications service facing to auto is still in the starting period. Tanaka, chief business-planning of AQUABIT said: "The real start of communications service is in future. Now the car is like an isolated personal computer."

Honda's "InternaviPremiumClub" provides the traffic congestion information service sharing among users ahead of the other companies. Users also display the praise to it. Toyota's "G-BOOK" first published vehicle navigation map data update service in the industry in 2007, which omit the trouble for users to update the map in the stores. Through "CARWINGS", Nissan provided advice on car navigation operation methods by operators, devoting the full service. It can be said that each company's service has reached a certain level.

However, as the communications module for vehicles is restricted by the low-speed communication, in fact it has a limited use range. In addition to KDDI's "CDMA20001xEV-DO" (2.4Mbps) by Toyota Motor, Honda and Nissan car manufacturers have adopted the PHS WILLCOM card (32 kbps). They have recently introduced a monthly subscription system on communication costs, about 1,000 yen a month. It can be said that each company is expanding the content and services in the communications constraints environment.

Then turning to the family, based on the optical fiber and ADSL access Mbps permanent environment has improved in Japan. A cost of several thousand yen per month. It can also carry out 54 Mbps communications through wireless LAN. Environmental standards is quite different from automotive communications.

Although there exists harsh restrictions in the vehicle communications environment, also with new trends. From 2009 to 2010, the large communications service"mobile WiMAX",  facing cars and mobile terminals, is expected to reach practical level, which can be equivalent to M ~10 Mbps speed of the wireless LAN and ADSL communication. As long as the vehicle to support WiMAX, it can exchange large-capacity video content with infrastructure on the road such as servers and other vehicles.

The "rear seat entertainment" only limited in senior models ago, but in the future, as long as the support of WiMAX, all vehicles will also be able to use this feature. Even without portable DVD, you can feel free to download images from an external server to watch.
