Clarion Radio Exchange Program and Audio System Troubleshooting

This bulletin is being revised to add the 2007 model year and add information to the radio model list. Please discard Corporate Bulletin Number 02-08-44-002B (Section 08 -- Body and Accessories).

This bulletin outlines the procedure for exchanging original equipment radios under warranty and provides the radio model part numbers for the vehicles listed above.

This bulletin applies to the following radio models:

1. When a customer contacts the dealership concerning a radio condition, the dealer must first use standard troubleshooting procedures outlined in this bulletin in order to reduce speaker, antenna, power supply and area reception conditions.

If a cassette tape is stuck in the unit, DO NOT attempt to remove the tape. The radio manufacturer will return the tape to your dealership if the tape is in good condition. Damaged or defective tapes will not be returned.

Important: DO NOT CUT the wires when removing any radio. CUT wires will VOID the warranty.

2. If the radio appears to be faulty, the dealer should obtain the following information prior to contacting the radio manufacturer. Call the radio manufacturer for the exchange unit or fax a completed copy of the form found at the end of this bulletin.

DO NOT remove the faulty unit until the replacement unit has been received. The dealer must make arrangements with the customer to return the vehicle for replacement of the faulty unit when the replacement unit has been received.

•	The Dealer name, address and Dealer Code

•	The R.O. Number

•	The Vehicle Identification Number (VIN)

•	The delivery date

•	The vehicle mileage

•	The radio Model Number (see attached table)

•	The description of failure (such as cassette won't eject, no illumination, reduced sound quality and the like)

•	The customer name and address

3. After the replacement radio is received from the manufacturer, notify the customer to schedule installation of the exchange unit. A return label and claim invoice will arrive with the replacement radio. If the customer DOES NOT RETURN to have their radio replaced WITHIN 30 DAYS, return the exchange unit to the manufacturer using the procedure outlined in step 6 below and note on the claim invoice that the customer did not return for the repair.
4. Verify that the model number is the same on the faulty unit, the exchange unit and on the claim invoice BEFORE installing the exchange unit. If the model number DOES NOT match, notify the radio manufacturer immediately.
5. After installation of the exchange unit, pack the faulty unit in the same manner as the exchanged unit was received. Enclose a copy of the claim invoice with the faulty unit.

INCORRECT and/or DAMAGED radios received by the manufacturer will be RETURNED to the dealer and a chargeback will be issued. The following conditions are NOT WARRANTABLE:

•	Liquid spill

•	Attempted theft

•	Modifications

•	Tampered units

6. Using the return label provided by the radio manufacturer, return the faulty unit to the radio manufacturer as outlined on the claim invoice. Faulty units must be returned to the radio manufacturer WITHIN THIRTY (30) DAYS of the exchange unit original shipment date.

Chargebacks will be processed for units outstanding over thirty days and will appear on the dealer's Statement of Account. Delinquent units, returned after a chargeback has been processed, will be returned to the dealer with the chargeback considered FINAL.

DO NOT return the radio to American Isuzu Motors, Inc., AIPDN or GMSPO. Return ONLY to the following Clarion Radio factory service center address.

File this bulletin in Section 1.5.8, page 28 of the GM Service Policy and Procedures Manual.

In Canada, warranty repairs and exchanges of Clarion radios are handled by the Canadian Electronic Service Centres (ESC) listed below. Refer to the GM Canada Service Policies & Procedures Manual article 1.5.10 AC-DELCO EXCHANGE PROGRAM for additional information.

Many audio systems returned under warranty are later found after inspection to have no defect. Please follow the procedures outlined below for troubleshooting audio system conditions. Refer to the Entertainment sub-section of the applicable service information for further information.

General Audio

Intermittent Condition (condition comes and goes)

Noisy Conditions

If the affected audio system is being compared in another vehicle, compare the same type of audio system and operating conditions.

Radio Reception

Reduced radio reception may be caused by factors other than the radio or antenna, such as the strength or distance of the radio station. AM reception is very sensitive to static from sources such as power lines, traffic lights, electrical signs, electrical storms in the area and windshield wipers.

FM radio signals can be blocked or reflected by tall buildings or mountains. Sometimes the antenna picks up a direct signal and a reflected signal at the same time, causing a distorted sound.

AM radio signals bend around obstacles and are less affected by tall buildings and mountains. This may increase the range of an AM station dramatically and cause interference (station mixing) between two stations that broadcast at the same frequency from different locations.

If reception on AM stations is weak, substitute a test antenna and lead. If reception continues to be weak, replace the radio with an exchange unit from the appropriate radio manufacturer.

If the customer comments of weak reception on FM stations, compare the reception on another radio. If a noticeable difference is heard, replace the radio with an exchange unit. If reception is the same, demonstrate the comparison to the customer.

No Sound from Radio

Verify that the fuses are good and replace the fuse if necessary.

If only AM radio reception is dead, verify that the antenna plug is good and repair or replace the antenna plug if necessary. If the condition still exists, install a test antenna. If AM reception is then normal, replace the faulty antenna. If the condition still exists, replace the radio.

Antenna

Fully extend and retract the antenna several times. If the antenna does not extend and retract normally, clean the antenna shaft and apply WD-40 lubricant or equivalent.

Verify antenna operation and replace if necessary.
