Understanding the PAC 31 GM Radio System
The PAC 31 GM Radio System is a versatile and cost-effective solution for upgrading the audio system in your General Motors vehicle. It allows you to integrate an aftermarket stereo with your factory radio, providing access to a wider range of features and audio options.
The system consists of a PAC interface module, which connects between your aftermarket stereo and the factory radio wiring harness. This module allows the two devices to communicate and share audio signals, ensuring seamless integration. The interface also provides additional features such as steering wheel control compatibility, Bluetooth connectivity, and the ability to retain factory chimes and warnings.
To understand how the PAC 31 GM Radio System works, it’s important to know the different components involved. The aftermarket stereo is the central hub of your audio system, providing the audio source and playback capabilities.
