Frequently Asked Questions
What wiring harness adapter fits a 2012–2016 Honda CR-V?
The 4th generation CR-V uses a connector compatible with the Metra 70-1729 Wire Harness Adapter for non-amplified trims. EX-L with Navigation trims require additional bypass harnesses for the navigation unit and backup camera. Confirm your trim and whether navigation is present before ordering, as the connector layout differs between navigation and non-navigation models.
Does the 2012–2016 Honda CR-V have a factory amplifier?
The standard audio system in most 4th generation CR-V trims does not include a factory amplifier. However, some EX-L models sold in certain markets were equipped with an upgraded audio system that included a separate Amplifier. Verify your specific configuration by checking for the presence of a multi-pin connector near the head unit that routes signal to an external location.
How do I retain steering wheel controls in a 2012–2016 Honda CR-V?
The 4th generation CR-V uses Honda’s CAN-bus steering wheel control system on EX and EX-L trims. A CAN-bus compatible SWC retention interface such as the iDatalink ADS-MSW or PAC SWI-CP2 is required to retain steering wheel audio functions. Standard resistor-based interfaces will not work with the CAN-bus SWC system on this generation.
What is the factory rear cargo speaker situation in a 2012–2016 Honda CR-V?
The 4th generation CR-V does not include a factory speaker in the rear cargo area on any trim level. All factory speakers are located in the four doors. If adding audio to the cargo area, new speaker wire runs and custom mounting are required. Some owners install a Compact Powered Subwoofer in the cargo area using speaker-level inputs from the rear door speaker wires.
What size are the factory door speakers in a 2012–2016 Honda CR-V?
The 4th generation CR-V uses 6 1/2″ Speakers in all four doors. These are a standard size with good aftermarket support. The door mounting depth on the 4th gen is sufficient for most standard-depth 6 1/2″ Speakers without spacer rings. Sound deadening on the inside of the door panels in this generation will noticeably improve the performance of upgraded door speakers.
