Sanyo HS706D-A - car navigation system

[Giovanni Dimitropoulos]

Sanyo and Nissan have jointly developed the "HS706D-A," the world's first car navigation system that features a terrestrial digital broadcast tuner supporting both standard TV and mobile TV broadcasts. To achieve this Sanyo developed proprietary two-branch and decoder LSIs which efficiently control two antennas and tuners and enables high-quality reception under a diversity of radio circumstances while driving.

The car navigation system can automatically switch to standard TV or mobile TV broadcast in accordance with the radio reception. When the reception is good it receives high-quality standard TV broadcast and when reception turns weak it switches to mobile TV broadcasts.
