Installation/Connections
First complete the electrical connections, and then check them for correctness. 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.
Before the installation
1.Remove the old unit from the dashboard.
Remove the outer trim frame.
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. Do not disconnect wires at this time!
2.Mark polarity of the speaker wires.
Marking the polarity of the speaker wires will make it easier to connect the existing speakers to your unit. 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.
While the old unit is playing, disconnect the wires from one speaker.
Take a length of masking tape and fold it around the wire so it forms a flag.
On the masking tape mark the polarity of the speaker wires (+ &
Double check that you marked the first speaker correctly by checking that the speaker wires are the same at the head unit.
Repeat this procedure for all of the speakers.
Mark the power, ground, and any other wires also.
