Power cord
Purple/white (REVERSEGEAR SIGNAL INPUT)
This is connected so that the navigation system can
detect whether the car is moving forwards or back-
wards. Connect the purple/white lead to the lead
whose voltage changes when the shift lever is put
in reverse. Unless connected, the sensor may not
detect your car traveling forward/backward proper-
ly, and thus the position of your car detected by the
sensor may be misaligned from the actual position.
Note: When you use the ND-PG1 speed pulse gen-
erator (sold separately), please make sure to con-
nect it.
Black, Orange/white, Red, Yellow

Yellow/black
When combining this navigation unit with a Pioneer car stereo,
if the car stereo has yellow/black leads, connect them to those
leads. In this way, when the guidance audio is output and
when you operate the system by voice, the car stereo is
automatically muted to reduce the car stereo volume.
Fuse resistor
Check the position of your car's backup
lamp (the one that lights up when the
shift lever is in reverse [R]) and find the
backup lamp lead in the trunk.
Note:

plied Installation manuals of both products

tion.
