After lots and lots and lots of
searching at different Radio Shacks,
Mobile Audio stores, and even raiding
Courtesy Nissan's warehouse to
try to find a plug for the telephone->radio
mute connector on the back
of my Bose headunit, I finally found
the plug.
Sure enough, one Radio Shack location
had what they call a "6-pin DIN
PLUG", catalog number 274-020A.
This plug fits the telephone plug on
the back of the Clarion/Bose head
unit perfectly and has all the pins
needed.... You just open it up and
solder wire(s) to the pin(s) you
need.
Now.. for explanation purposes imagine
that you've got the radio out
of the dashboard and you're looking
at it from behind. Locate the
round 6-pin DIN connector. It's
got holes for six pins. The BOTTOM
LEFT pin is the telephone usage
signal input. When this pin is grounded, the radio is muted.
Side note: at this point, if you
want to check that yours is working
correctly, do this: Stick a pair
of tweezers in the telephone usage
signal input pin (BOTTOM LEFT) and
the ground pin (TOP RIGHT). The
radio should mute.
So... All you have to do to get radio
muting with your handsfree kit
is get the Radio Shack 6-spin DIN
plug, Cat. no. 274-020A, and solder
a wire to the bottom left pin when
looking from behind. Stick this
connector in the back of the radio,
and connect the wire to your phone
handsfree car kit in such a way
that the wire is grounded when the
telephone is used. (This is how
the Nokia car kit radio mute output
works... I am not familiar with
other brands).
Hope this helps... |
