3rd Gen Chassis Codes: RL7 • RL8 | Model Years: 2005, 2006, 2007, 2008, 2009, and 2010
This page provides the complete 2005–2010 Honda Odyssey radio wiring diagram for the 3rd generation Odyssey (chassis codes RL7 and RL8). Use this guide when replacing the factory head unit or troubleshooting audio in a 2005, 2006, 2007, 2008, 2009, or 2010 Honda Odyssey.
The 3rd generation Odyssey received a significant interior refresh and expanded the available trim and audio options. The Touring trim introduced a factory navigation system integrated into the head unit, adding complexity to any radio replacement. EX-L trims retained the rear DVD entertainment system option with improved screen resolution. The factory audio system on non-navigation trims used Honda’s updated double-DIN radio opening, making aftermarket head unit installation more accessible than on earlier generations.

Frequently Asked Questions
Does the 2005–2010 Honda Odyssey Touring have a factory navigation system?
Yes. The Touring trim of the 3rd generation Odyssey includes a factory navigation head unit integrated into the double-DIN radio opening. This navigation unit uses a separate GPS module and navigation computer. Replacing the factory navigation radio requires a navigation bypass harness in addition to the standard wiring harness adapter. Non-navigation EX and EX-L trims use a standard Double DIN Head Unit that is considerably simpler to replace.
What wiring harness adapter fits a 2005–2010 Honda Odyssey?
For non-navigation 3rd generation Odyssey trims, Metra 70-1727 Wire Harness Adapter is a commonly used adapter. Navigation-equipped Touring trims require a dedicated navigation bypass harness in addition to the radio harness. Always specify whether your Odyssey has navigation when purchasing adapter components, as the connector layout and required interfaces differ between the two configurations.
How do I keep the rear DVD entertainment system working when I replace the front radio in a 2005–2010 Honda Odyssey?
The rear DVD entertainment system in the 3rd gen Odyssey operates on a partially independent audio circuit from the front head unit. When replacing the front radio, the rear system’s audio output to the rear cabin speakers must be preserved through the wiring harness. Using a factory-compatible wiring harness adapter that maintains the rear entertainment audio connections is the safest approach. Cutting the factory connector risks severing the rear entertainment audio circuit.
Does the 2005–2010 Honda Odyssey have steering wheel audio controls?
Yes. EX and above trims of the 3rd generation Odyssey include steering wheel audio controls. A steering wheel control retention interface is required when replacing the head unit. The 3rd gen Odyssey uses Honda’s resistive SWC system, compatible with interfaces such as the PAC SWI-RC. CAN-bus interfaces designed for newer Honda models are not needed for this generation.
What size are the second and third row speakers in a 2005–2010 Honda Odyssey?
The 3rd generation Odyssey provides speaker coverage across all three rows, with second-row speakers in the B-pillar or side panels and third-row speakers in the rear side trim panels. Speaker sizes in the rear passenger areas vary by trim. EX-L with rear entertainment uses a slightly different rear speaker configuration than non-entertainment EX trims. Confirm the speaker locations and cutout dimensions in your specific trim before ordering replacement speakers for the rear cabin.
