Frequently Asked Questions about the 2006 GMC Envoy Radio Wiring Diagram

Q: What is the purpose of the yellow wire in the radio wiring diagram?

A: The yellow wire is the constant 12V+ wire, meaning it always has power even when the key is turned off. This wire is used to keep the radio’s memory alive, so it doesn’t lose its settings and presets when the vehicle is turned off. If this wire is not connected, the radio will lose all of its saved data every time the vehicle is turned off.

Q: What is the purpose of the red wire in the radio wiring diagram?

A: The red wire is the accessory 12V+ wire, meaning it only has power when the key is in the accessory or on position. This wire is used to turn on the radio when the vehicle is started, and to power any accessories connected to the radio, such as a CD changer or satellite radio tuner.

Q: What is the purpose of the black wire in the radio wiring diagram?

A: The black wire is the ground wire, which completes the electrical circuit and provides a path for the current to flow back to the battery. Without a proper ground connection, the radio will not work at all.

Q: What is the purpose of the orange wire in the radio wiring diagram?

A: The orange wire is the illumination wire, which controls the brightness of the radio’s display. This wire is connected to the vehicle’s dimmer switch, so the display will dim or brighten depending on the position of the switch.

Q: What is the purpose of the blue/white wire in the radio wiring diagram?

A: The blue/white wire is the amplifier remote wire, which is used to turn on an external amplifier or other accessory. This wire is only used if your radio has a built-in amplifier or if you’re connecting an aftermarket amplifier to your system.

Q: What is the purpose of the brown wire in the radio wiring diagram?

A: The brown wire is the phone mute wire, which is used to mute the radio when a phone call comes in. This wire is only used if your vehicle is equipped with a factory hands-free phone system.
