1. Connect the electrical connectors.  

2. Install the antenna and mounting fastener.  

3. Install the headliner. Refer to INSTALLATION .  

4. Connect the battery negative cable.  

CABLE-INSTRUMENT PANEL ANTENNA 

REMOVAL 

INSTRUMENT PANEL ANTENNA CABLE 

1. Disconnect and isolate the battery negative cable.  

2. Remove the instrument panel. Refer to REMOVAL . 

3. Disconnect the antenna cable from radio by pulling the locking antenna connector (2) away from radio.  

4. Disengage each of the retainers that secure the cable to the instrument panel.  

WARNING:

Disable the airbag system before attempting any steering wheel, steering 
column, seat belt tensioner, side airbag, or instrument panel component 
diagnosis or service. Disconnect and isolate the battery negative (ground) 
cable, then wait two minutes for the airbag system capacitor to discharge 
before performing further diagnosis or service. This is the only sure way 
to disable the airbag system. Failure to take the proper precautions could 
result in accidental airbag deployment and possible personal injury.

CAUTION: Pulling the antenna cable straight out of the radio without pulling on 

the locking antenna connector could damage the cable or radio.

WARNING:

Disable the airbag system before attempting any steering wheel, steering 
column, seat belt tensioner, side airbag, or instrument panel component 
diagnosis or service. Disconnect and isolate the battery negative (ground) 
cable, then wait two minutes for the airbag system capacitor to discharge 
before performing further diagnosis or service. This is the only sure way 
to disable the airbag system. Failure to take the proper precautions could 
result in accidental airbag deployment and possible personal injury.

NOTE:

The USB protective door can be serviced separately and does not require the 
replacement of the entire radio assembly.

The radio receiver operates only when the ignition switch is in the ON or ACCESSORY positions.

For complete circuit diagrams, refer to the appropriate wiring information. 

STANDARD PROCEDURE 

RADIO BACKUP 

The radio hard drive (HDD) can be backed up to save customer data in the event that a radio replacement is 
required. This procedure can only be done with all radios with a hard disk drive. All other radios do not have a 
HDD. 

1. Turn the ignition to RUN, engine OFF.  

2. Power on the external HDD.  

3. Connect the external HDD to the radio using the USB (Universal Serial Bus) cable. The radio display will 

change to the "Manage My Files" screen.  

4. Connect the scan tool and preform the following steps to place the radio into "Dealership Mode":

5. Follow the on screen instructions on the radio to back up the radio HDD.  

REMOVAL 

RADIO 

1. Disconnect and isolate the battery negative cable.  

2. Remove the instrument panel center trim panel.  

3. Remove the radio mounting fasteners. 

NOTE:

The USB protective door can be serviced separately and does not require the 
replacement of the entire radio assembly.

NOTE:

REQ and RET radios only must be put into "Transportation Mode" before 
removal. With Ignition in RUN or ACCESSORY, press SET and SCAN 
simultaneously until the radio displays "TRANSPORTATION" on the display or 
for 5 seconds.

CAUTION: Pulling the antenna cable straight out of the radio without pulling on 

the locking antenna connector could damage the cable or radio.

RADIO NOISE SUPPRESSION COMPONENTS 

DESCRIPTION 

RADIO NOISE SUPPRESSION COMPONENTS 

Radio Frequency Interference (RFI) and Electro Magnetic Interference (EMI) can be produced by any on-board 
or external source of electromagnetic energy. These electromagnetic energy sources can radiate electromagnetic 
signals through the air, or conduct them through the vehicle electrical system. 

When the audio system converts RFI or EMI to an audible acoustic wave form, it is referred to as radio noise. 
This undesirable radio noise is generally manifested in the form of "buzzing," "hissing," "popping," "clicking," 
"crackling," and/or "whirring" sounds. In most cases, RFI and EMI radio noise can be suppressed using a 
combination of vehicle and component grounding, filtering and shielding techniques. This vehicle is equipped 
with factory-installed radio noise suppression devices that were designed to minimize exposure to typical 
sources of RFI and EMI; thereby, minimizing radio noise complaints. 

Radio noise suppression is accomplished primarily through circuitry or devices that are integral to the factory-
installed radios, audio power amplifiers and other on-board electrical components such as generators, wiper 
motors, blower motors, and fuel pumps that have been found to be potential sources of RFI or EMI. External 
radio noise suppression devices that are used on this vehicle to control RFI or EMI, and can be serviced, include 
the following: 



Engine-to-body ground strap - This length of braided ground strap has an eyelet terminal connector 
crimped to each end. One end is secured to the engine cylinder head(s). The other is secured to the 
plenum.  



Resistor-type spark plugs - This type of spark plug has an internal resistor connected in series between 
the spark plug terminal and the center electrode to help reduce the production of electromagnetic radiation
that can result in radio noise.
