2. The 3300 has five major components that we recommend you install first before hooking up everything to the control box. You’ll be running a cable for the microphone unit, the LCD screen, the power cable, the GPS antenna, and the in-car radio input.
Parrot does a nice job of labeling all the wires for you, so hopefully you won’t get confused. See Figure 11-3.
How you connect your car radio depends on what sort of connectors it has on the backside of the radio. Here are three possible options:
a. Line-in connectors: Take the green (“positive”) and brown (“negative”) wires and attach them to the corresponding +/- inputs of your radio; plug the end of the yellow mute cable into the mute interface. Do not connect the yellow mute wire; this also mutes the Parrot. Because most line inputs are auxiliary lines, most radios switch sources automatically when input is detected. If it does not switch automatically, the user will have to switch manually when a phone call is made or received.
Line-in connectors are more common on aftermarket radios.
Most stock radios make use of the car kit’s ISO connectors.
(See Figure 11-4.)
b. ISO connectors: Take the factory harness out of the radio and plug it into the female ISO connector of the car kit. Take the male ISO connector from the car kit and plug it into the radio. The yellow mute wire is only needed in vehicles that have more than four speakers. Because the ISO connector has support for up to four speakers, any speakers connected to the car kit will automatically be muted by the relay (the smaller black box). If you do need to connect the yellow mute wire, connect it to the mute input at the

back of the radio. If the radio does not have a mute input, the ground signal from the mute wire can be used in a power relay (which you can buy at Radio Shack) to shut off the ignition connection at the radio. This in effect mutes all the speakers in the vehicle.
c. Other connectors: You’ll need to get an ISO adapter cable for that particular radio’s audio input connector. Try www.carstereo

3. Now you can hook up the cables as shown in Figure 11-3:
a. Disconnect the car radio’s speaker and power harnesses.
b. Connect the male connectors of the audio cable and the power supply cable to the car radio.
c. Connect the vehicle’s audio and power supply leads to the female connectors of the electronic box.
d. If the car radio has a Mute input, connect the yellow wire on the Mute cable to one of the Mute inputs.
4. Connect the power supply cable.
It’s fairly straightforward, but you have to ignore the manual here. If your vehicle does not use the ISO connectors, cut off the gray ISO connectors — be sure to cut the red and orange wires after the white plastic fuses in the power supply cable so that they are still in the wiring path. If your car does have ISO connections, use them. Attach the red wire of the power cable to the permanent 12V connection (also called the 12V constant); the orange wire to the 12V ignition connection (also called the 12Vaccessory); and the black wire to the ground connection (amusingly called the earth connection in the manual).
That’s it! You’ve installed the CK3300. That wasn’t hard, was it?
You do not want to leave your orange wire connected to the permanent 12V circuit — you might find your batteries dead after a short while. Take a second to verify the electric wiring of the power bundle. In some vehicles, it is necessary to reverse the positions of the red and orange wires. This operation is simply done by reversing the fuse holders. You’ll know that you have it right when you turn off the car and see a goodbye message on the LCD screen. If you don’t see that, your ignition and permanent 12V connections need to be reversed.

Understanding your powered connections
In most aftermarket device manuals, you'll hear references to wires like +12Vrun or +12Vconstant wires. What does this all mean? Many of these wires are actually the same thing called by different names. Most connections have two main power wires:
^ Ignition: The ignition wire is so-called because it is only powered when the ignition key is turned to its "
