    Eric, you can fit a single DIN radio or double DIN radio. Simply choose which radio you want:

    Single DIN Car Stereo for 2003 Buick LeSabre

    With the car stereo wiring harness and car radio dash kit, you should be able to install your after market radio with ease. If you’ve never installed car audio before, we advise you to take your car to an experienced mobile audio installer. Hope this helps. Good luck with your 2003 Buick LeSabre stereo installation.

    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
    Steering Wheel Control Adapter for Valor Radio

    If you have never installed car audio before, we advise you to take your car to an experienced mobile audio installer. Hope this helps. Good luck with your 2003 Buick Park Avenue stereo installation.
