Copyright 2022 General Motors LLC. All Rights Reserved. Service Bulletin Bulletin No.: 20-NA-051 Date: October, 2022 INFORMATION Subject: Alpine Radio Exchange Program Brand: Model: Model Year: VIN: Engine: Transmission: from to from to Chevrolet All Medium Duty (LCF) 2016 2023 All All Involved Region or Country North America Additional Options (RPOs) Equipped with Alpine Bluetooth Radio Information Important: Service agents must comply with all International, Federal, State, Provincial, and/or Local laws applicable to the activities it performs under this bulletin, including but not limited to handling, deploying, preparing, classifying, packaging, marking, labeling, and shipping dangerous goods. In the event of a conflict between the procedures set forth in this bulletin and the laws that apply to your dealership, you must follow those applicable laws. This bulletin outlines the procedures for using the Alpine Exchange Program (the “Exchange Program”). The Exchange Program must be used when any Alpine radio covered by this bulletin is repaired under warranty and may also be used for radio repairs not covered under warranty. Contact Alpine directly for pricing and payment methods applicable to radio repairs not covered under warranty. This bulletin applies to the following Alpine radio models: Alpine Radio Model No. Radio Exchange Bank Stock Description CDE-143BT Yes AM/FM CD iLX-207 Yes AM/FM CD HCE-C1100 Yes Back Up Camera Note: Alpine brand radios are easily identified by the Alpine logo and model numbers imprinted on their faceplates. Audio System Troubleshooting Many audio systems returned under warranty are later determined to have had no defect. Please follow the procedures outlined below for troubleshooting audio system conditions. Refer to the Entertainment sub-section of the applicable Workshop Manual for further information. General Audio Intermittent Conditions (condition comes and goes) • Ask the customer to identify the condition with specificity (such as abnormal noise, failure in all modes). • Try to reproduce the intermittent condition, duplicating similar road qualities under which the customer experienced the condition. Noisy Conditions • Inspect for grounded antenna lead. • Inspect for tight and secure battery terminals. • Verify that the radio is chassis-grounded. • Verify that the chassis harness is connected securely to the radio. Radio Reception Radio reception may be affected by factors other than the radio or antenna, such as signal strength or distance to 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. Page 2 October, 2022 Bulletin No.: 20-NA-051 AM radio signals bend around obstacles and tend not to be affected by tall buildings or mountains. As a result, the range of an AM station may increase 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. FM radio signals can be blocked or reflected by tall buildings and mountains. Sometimes the antenna picks up a direct signal and a reflected signal at the same time, causing a distorted sound. If the customer complains of weak reception on FM stations, check it in comparison to the reception on another radio. If the other radio’s FM reception is noticeably better, replace the radio with an exchange unit. If reception is the substantially similar or the same, explain or demonstrate the comparison results to the customer. No Sound from Radio Check the condition of the fuses and replace any that are non-functioning or burnt. 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. Pairing and Clearing Bluetooth The radio can hold a maximum of three (3) paired phones. If the radio is not accepting a pairing request – a clearing command is needed to clear the previously paired phones. Once the Bluetooth memory is cleared, new phones may then be paired with the radio. Bluetooth Functionality Exchange Procedure (USA) 1. When a customer contacts the dealership concerning a radio issue, the dealer must first use standard troubleshooting procedures as outlined in this bulletin to determine whether the source(s) of the problem(s) is a speaker, antenna, power supply, area reception or other non-radio condition – as opposed to the radio itself. If a CD is stuck in the unit, DO NOT attempt to remove it. The radio manufacturer will return any stuck CDs to your dealership. Important: DO NOT CUT any wires when removing a radio. Any CUT wires will VOID the warranty. 2.

They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition.
