This page provides the complete 2008–2012 Honda Accord radio wiring diagram for the 8th generation Accord (chassis codes CP1, CP2, and CP3 for the sedan; CS1 for the coupe). Use this guide when replacing the factory head unit or troubleshooting audio in a 2008, 2009, 2010, 2011, or 2012 Honda Accord.
The 8th generation Accord moved to a larger platform and introduced more sophisticated audio options. EX-L trims often feature a factory amplifier driving door and rear deck speakers. Navigation-equipped models require a bypass solution to maintain steering wheel audio controls when replacing the head unit. The 2010–2012 refresh updated the interior but largely retained the same audio wiring layout.
