Connecting the System
Extension lead
(for speed signal)
Violet/white (REVERSE GEAR SIGNAL INPUT)
This is connected so that the navigation system can detect
whether the vehicle is moving forwards or backwards.
Connect the violet/white lead to the lead whose voltage
changes when the shift lever is put in reverse. Unless
connected, the sensor may not detect your vehicle traveling
forward/backward properly, and thus the position of your
vehicle detected by the sensor may be misaligned from the
actual position.
Note
When you use a rear view camera, please make
sure to connect this lead. Otherwise you cannot
switch to rear view camera picture.
CAUTION
Be sure to use only the supplied extension lead. Use of another
lead could cause fire, smoke and/or damage this navigation
system.
Extension lead
