2017-2023 Honda Ridgeline Audio System: Solving Popping, Crackling & Connectivity Issues

Symptoms of a Failing Audio System

Problems with the Ridgeline's audio system can range from minor annoyances to complete failure. Many issues are linked to software glitches or a faulty wiring harness rather than a complete component failure.

Popping, Crackling, or Static Noises

This is one of the most widely reported issues. Owners describe loud, intermittent popping or crackling sounds from the speakers, which can occur on any audio source. These noises are often linked to a poor connection in the MOST bus network, which connects the head unit to the amplifier and other components. The issue can be more frequent on hot days, suggesting a thermal component to the failure. In some cases, the noise precedes a total loss of audio.

No Sound from Speakers

The head unit may appear to be working correctly—displaying radio stations or song information—but no audio comes from any speaker. This can be caused by a failed internal amplifier in the head unit, a separate failed amplifier on models equipped with one, or a communication breakdown on the MOST bus network. Sometimes the audio will return after the vehicle has been off for a period of time.

Blank or Flickering Display Screen

The center display may go blank, flicker, or freeze while the audio continues to play. This is another symptom often tied to the faulty MOST bus network connection, which was the subject of a recall. The system may also reboot intermittently or get stuck on a loading screen.

Bluetooth, Apple CarPlay, or Android Auto Issues

Difficulty pairing a phone, frequent disconnections, or no audio during calls or media playback through a connected device are common complaints. These are often software-related. Owners report that using genuine Apple cables and ensuring both the phone and the vehicle's infotainment software are up to date can sometimes help. In some cases, a factory data reset of the infotainment system is required to resolve persistent connectivity problems.

'CODE' Displayed on Screen

After the vehicle's battery has been disconnected or replaced, the radio may display the word 'CODE' and refuse to function. This is the anti-theft system, which requires a specific code to unlock the unit. This is a normal security feature, not a sign of failure.

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

Recall: MOST Bus Communication Failure (NHTSA Campaign ID: 23V-431)

Honda issued a major recall for over 1 million vehicles, including some Ridgeline models, for a faulty MOST communication coaxial cable. The improperly manufactured cable terminals could deform, leading to a poor connection. Warning signs of this issue include popping or crackling sounds from the speakers and a flickering display. The primary safety risk cited was the potential for the rearview camera to fail, but the faulty connection is also the root cause of many audio system complaints. The fix involves a dealer installing an improved cable harness and a cover to ensure a solid connection.

Recall: Rearview Camera Harness (NHTSA Campaign ID: 22V-867)

For 2017-2019 Ridgeline models, a recall was issued because the wiring harness for the rearview camera could break from the stress of opening and closing the tailgate. While primarily affecting the camera, this highlights the potential for wiring issues in the vehicle.

Owner Complaints and Lawsuits

Numerous owners have filed complaints and joined class-action lawsuits regarding the popping and crackling noises, alleging the infotainment systems are defective. Many of these issues are traced back to the MOST bus network problems.

Buying a Used Ridgeline Audio System

When purchasing a used audio component for your 2017-2023 Ridgeline, compatibility is the most important factor. Mismatched parts will not work correctly, if at all.

Verifying Compatibility

• Match Part Numbers: The surest way to ensure compatibility is to match the OEM part number from your old unit to the replacement.
• Trim Level Matters: The audio systems are different between trim levels. The standard system (Sport, RTL) uses a 200-watt, 7-speaker setup, while the premium system (RTL-E, Black Edition) has a 540-watt, 8-speaker setup. Components are not interchangeable.
• Navigation vs. Non-Navigation: Head units for vehicles with and without factory navigation are different and cannot be swapped.
• Check Connectors: Physically inspect the connectors on the replacement unit to ensure they match your vehicle's wiring harness.

Anti-Theft Codes

If you are replacing the head unit, you will likely need an anti-theft code to unlock it after installation. You can retrieve this code in a few ways:

1. Check the Glove Box: Sometimes a sticker with the 5 or 6-digit code is placed inside the glove box.
2. Retrieve from the Unit: With the radio asking for the code, press and hold presets 1 and 6, then turn the ignition to the 'ON' position. The radio's serial number should display.
3. Honda's Website: You can enter your vehicle's VIN and the radio's serial number on Honda's official radio code lookup site (radio-navicode.honda.com) to get the unlock code for free.

Cost to Replace Ridgeline Audio Components

Prices can vary significantly based on the specific component and whether you choose new or used parts. Labor for replacement typically involves removing dashboard trim and can take 1-2 hours.
