used for radio and component repairs not covered under warranty. Contact Alpine directly
for pricing and payment methods applicable to radio and component repairs not covered
under warranty.
This bulletin applies to the following Alpine radio and component models:

harnesses will be provided for proper adaption; the main harness which goes
between the radio and the factory harness, and the USB/AUX harness which now
includes the microphone.
NOTE: Alpine brand radios are easily identified by the Alpine logo and model
numbers imprinted on their faceplates.
NOTE: Damaged Backup Camera Cable Extensions (PT # 8-97543-875-0) that are
not warrantable should be ordered through AIPDN.

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.
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
These radios support (A2DP) BT audio streaming, phone book, call history, etc. However,
different cell phones support different levels of Bluetooth features. Please confirm what
features the affected cell phone will support before assuming there is a malfunction with
the radio.
Back Up Camera Functionality
Check the radio and back up camera connectors for proper seating. Check the wiring
between the radio and back up camera for opens and shorts. Ensure that the reverse
input to the radio is providing the proper signal. Refer to the applicable Workshop Manual
for further details and information.
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. If after a proper diagnosis it is determined that the radio or other component is
faulty, the dealer should document the following information prior to contacting the
radio manufacturer.
a. Dealer name, address and dealer code
b. R.O. number
c. Vehicle Identification Number (VIN)
d. Vehicle delivery date
e. Vehicle mileage
f. Radio or component model number (see radio part number label)

g. Description of failure (such as, CD won’t eject, no illumination, reduced
sound quality and the like)

unit back to the manufacturer using the procedure outlined in Step 5 below and
note on the claim invoice that the customer did not return for the repair.

the faulty (OLD) radio or component, the (NEW) exchange unit and the claim
invoice all match. If the model numbers DO NOT match, notify the manufacturer
