  1. Eli, if you’re installing an aftermarket radio into your 2003 Buick Park Avenue and want to retain your steering wheel controls it is possible but it depends on the manufacturer of your aftermarket radio:

    Steering Wheel Control Adapter for Alpine Radio
    Steering Wheel Control Adapter for Blaupunkt Radio
    Steering Wheel Control Adapter for Clarion Radio
    Steering Wheel Control Adapter for Eclipse Radio
    Steering Wheel Control Adapter for JVC Radio
    Steering Wheel Control Adapter for Kenwood Radio
    Steering Wheel Control Adapter for Pioneer Radio
    Steering Wheel Control Adapter for Sony Radio
