Using the Speaker Input
The unit can interrupt the system (navigation or telephone) of the car. The audio can also be played back on the unit if the car system of the audio (CD, etc.) is selected as the source.
The unit makes the sound interruption according to the sound output level of the car system. If any of the following settings are not correctly made, sound may not interrupt, or loud sound may suddenly interrupt.
Setting the Speaker Input Mode
The following explains how to install the system (navigation/telephone) in your car. While listening to the radio, you can have navigation voice guidance or a received telephone call interrupt automatically. You can also select the speaker input mode (FACTORY SYS) on the source selection screen.
Setting items: FACT SYS SET
Setting content: OFF / SOURCE / INT / BOTH
SOURCE: The system (CD, etc.) of the car can be selected as a source.
Navigation/telephone voice of the car is not interrupted.
INT: Interrupts only the navigation/telephone voice of the car.
BOTH: The system (CD, etc.) of the car can be selected as the source.
Navigation/telephone voice of the car is interrupted.
OFF: Operation and setting of the speaker input mode is not performed.

•Depending on the conditions of use, the INT or SOURCE setting is recommended.
•If INT is set, do not output CD audio from the car system.
•With BOTH set, if the source is set to other than FACTORY SYS, do not output CD audio, etc., from the car system.
•If OFF is to set, speaker input mode settings cannot be made.
Displaying the Speaker Input Volume Level
The volume level of the speaker input is displayed numerically. Adjustment can be made only on the system in your car (standard car audio, etc.), and cannot be made by this unit.
Setting items: FACT SYS LV
Setting content: 0 to 2 L / 3 to 15: OK / 16 to 18 H
L:Volume level is LOW
OK: Volume level is optimally adjusted
H:Volume level is HIGH
Adjust the volume for optimum level.
•Set the volume as loud as possible, but before the onset of distortion (The volume level should not exceed 15). Even if OK is displayed, if any distortion is apparent, decrease the car audio's volume.
