Overview

The SH-NaviJ2 is the second product to appear in the SH-NaviJ Series. It increases the bus width of the DDR2-SDRAM memory interface to 32 bits, enabling high-speed display of sophisticated graphics and support for a wider variety of applications through the use of dual-screen display. In-vehicle network functions are further enhanced by the expansion of the CAN interface to two channels and the addition of a MOST interface.
