System Description

INFOID:0000000001728628

Multi AV system means that the following systems are integrated.

• Two AV communication lines (H, L) connect between units that configure MULTI AV system. NAVI control

unit controls by sending/receiving data one by one with each unit (slave unit) that configures them com-
pletely as a master unit.

• Two AV communication lines (H, L) adopt a twisted pair line that is resistant to noise.
• NAVI control unit is connected by CAN communication, and it receives data signal from ECM, combination

meter. It computes and displays fuel economy information value with the obtained information. Sending/
receiving of data signal is performed by BCM. Also, it sends the required signal of vehicle setting and
receives the response signal.
