Product Description

Car-specific Fakra Hi-fi Soft mute

Drive & Talk enables the use of the car speakers for phone con-

versation.

Speaker-function: This is achieved by using the mutebox-relays

to disconnect the rear speaker and connect the front speakers

to the carkit. This way the radio sound is muted and the sound

from the carkit is sent through the cars front speakers. You will

achieve a perfect hands-free sound without interference from

the car radio.

For a complete cableset two item numbers are needed. The 1st

item number includes the mutebox and the car-specific cable-

set. The 2nd item number is a carkit-specific adaptor-cable for

adapting the car-specific cable to the carkit.

Power supply of the carkit: All car-specific cablesets have an in-

tegrated carkit-powersupply. In the car-specific cablesets the

constant 12v and the ground wire are connected to the 6 way

connector. This connector is to be fitted to the 6 way connector

on the carkit adaptor. This way powersupply, of the carkit, is

achieved without cutting the cars wiringloom.

Mute function: The mutewire is connected from the carkit to the

mutebox through the carkit adaptor. The mutewire is also con-

nected to the radios mute input. This enables the use of the ra-

dios built in mute function. If the radios mute input pin is un-

known the mute wire can be found in a yellow flywire fitted

with a bullit connector. Please note that not all radios are

equipped with a mute function.

Installation description

Car-specific Fakra Hi-fi Soft mute

Needed items:

A. Mutebox.

B. Car-specific cable.

C. Carkit adaptor.

D. Carkit.

Note: The Mutebox

is always delivered with car-specific cable

Installation:

1. Connect the mutebox to the Car-specific cableset. The end marked

“Radio” is connected to the end with the single 8 way connector

. The

other end marked “Speakers” is connected to the 6 and 8 way connec-

tors

2. Remove the radio unit from the centre consol.

3. Disconnect the radio connector from the radio.

4. Insert the Car-specific cable

between the connector on the radio

and the connector on the cars wiring loom. If there, in the Fakra connector removed from the radio, are inserted small plugs which pins has no connection to the radio.

Then these plugs has to be moved to the Fakra connector fitted into the radio. These small plugs can be used for ex. CD-changer, navigation, Optic Most-bus, Optic Can-

bus or Steering wheel controls.

5. Please check the configurations of the ground, ignition and constant 12v in connector

. The red wire should be the constant 12v, the blue Ignition, and the

black should be ground. The two bullet connectors on the Car-specific cableset gives you the possibility to connect the blue ignition wire to the red constant wire if this

is preferred. Note: If no ignition exist in radio connector the Ignition wire is connected to the red constant 12V bullet connector, or a IGNIBOX item nr. 69600 can be in-

serted to generate a artificial ignition. If a real Ignition is preferred for the carkit please disconnect the blue wire from the constant 12V bullet connector and connect it

to a real ignition found elsewhere (for an example in the fusebox).

6. The Carkit adaptor

is connected to connector

from the car-specific cableset

7. The carkit is unwrapped & connected. The original speaker and powersupply cable is not used with this cableset. Connector

from the carkit adaptor

is con-

nected to the carkit-powersupply input. Connector

from the carkit adaptor

is fitted to the speaker output on the carkit.

8. Check the position of the mute wire. The yellow mute wire

from the carkit adaptor is normally prefitted to the mute-input on the radio. If the placement of the

radios mute input-pin is unknown the mute-wire can be found in a yellow wire with a female bullet near one of the car-specific connectors on the cableset

. By con-

necting the mute-wire you achieve that the radio writes ”Mute” or ”Phone” when the phone is used and at the same time pauses the CD-player. Note: In some car

models it is necessary to connect the yellow mutewire to the radios mute input, to achieve a complete mute of the radio sound.

adjusted. Connect the phone to the carkit and adjust the phone volume to its middle position. Make a call and adjust

the volume to an appropriate level by using the adjustment screw on the back of the mutebox. Note: In some car models it is necessary to have the radio turned ON

to get carkit sound from this solution.
