2. Mark Polarity of the Speaker Wires
Automotive audio equipment installations can be troublesome at
times, even to the most experienced of installation technicians.
If you are not confident working with electrical wiring, removing
and reinstalling interior panels, carpeting, dashboards or other
components of your vehicle, please call your dealer in order to
have the unit professionally installed.
1. Remove the Old Unit from the Dashboard
DIN Front Mount
DO NOT DISCONNECT WIRES
AT THIS TIME!
IMPORTANT: Remove the two transport screws from the top of
the unit before installing.
2. Insert the keys supplied with the
old unit into both sides of the unit
as shown in figure below until
they click. Pull to remove the old
unit from the dashboard.

1. While the old unit is play-
ing, disconnect the wires
from one speaker
2. Take a length of masking
tape and fold it around the
wire so it forms a flag.
3. On the masking tape mark
the polarity of the speaker
wires (+ & - ), as well as
left or right, and front or
rear.
4. Double check that you
marked the first speaker
correctly by checking that
the speaker wires are the
same at the head unit.
5. Repeat this procedure for
all of the speakers.
6. Mark the power, ground,
and any other wires also.
Marking the polarity of the speaker wires will make it easier to
connect the existing speakers to your car radio.Consult wiring
diagram of existing head unit before disconnecting any wires.
If you are not positive of the polarity of the existing wires
from the speakers to the head unit, install new wires.
