The 3rd generation CR-V introduced a more car-like interior and updated audio electronics. EX-L trims included a factory navigation system with a proprietary head unit that requires a specific bypass solution when upgrading. Base and EX trims used a standard single-DIN or double-DIN head unit. Front and rear door speakers were standard across most trims, with no factory subwoofer on any configuration.

Frequently Asked Questions
Does the 2007–2011 Honda CR-V EX-L with Navigation have a different radio?
Yes. The EX-L Navigation trim in the 3rd generation CR-V uses a factory navigation head unit that is integrated with GPS, backup camera, and vehicle information systems. Replacing this unit requires a navigation bypass harness in addition to the standard radio harness. Non-navigation EX and LX trims use a standard radio that is considerably simpler to replace with an Aftermarket Head Unit.
What wiring harness adapter fits a 2007–2011 Honda CR-V?
The 3rd generation CR-V uses a Honda radio connector compatible with Metra 70-1729 Wire Harness Adapter for non-navigation trims. Navigation-equipped models require additional adapters to handle the backup camera video signal and navigation unit connections. Confirm your exact trim and audio configuration before purchasing harness components.
What size are the factory speakers in a 2007–2011 Honda CR-V?
The 3rd generation CR-V uses 6 1/2″ Speakers in all four door panels across most trims. EX-L with Navigation may include additional tweeter locations. The cargo area does not have a factory speaker on any 3rd gen trim. Aftermarket 6 1/2″ Speakers are a direct fit in all four door locations without requiring mounting adapters.
Does the 2007–2011 Honda CR-V have steering wheel audio controls?
Yes. The EX and EX-L trims of the 3rd generation CR-V include steering wheel audio controls. A steering wheel control retention interface is required when replacing the head unit in these trims. The PAC SWI-RC or iDatalink ADS-MSW are compatible options for this application. LX trim does not include SWC functionality.
How do I retain the factory backup camera when replacing the radio in a 2007–2011 Honda CR-V EX-L?
The factory backup camera in the navigation-equipped 3rd gen CR-V sends its video signal through the factory navigation head unit. When replacing the head unit, the camera’s video output must be connected to the aftermarket radio’s rear camera input. A video bypass harness or a standalone camera interface adapter is typically needed to route the factory camera signal to the new head unit’s camera input.
