Audio Interfaces

Frequently Asked Questions

A compatible interface can let an aftermarket stereo communicate with vehicle-specific wiring and electronics and may retain selected factory features. The functions vary by vehicle and interface, so confirm the supported amplifier, controls and other features for your trim and the receiver you plan to install.

Sometimes. You need an interface when the aftermarket radio or added audio equipment must communicate with or retain factory systems that a basic wiring harness cannot handle. Depending on the vehicle, that can include the factory amplifier, steering-wheel controls, warning chimes, camera, or telematics. Match the interface to the exact vehicle, factory audio package and features, and the aftermarket radio or equipment before ordering.
