Audi A4/RS 4/S4 2002-2008 (with Symphony or NAV radio)

This stereo installation kit has been engineered to help you install either a 2” tall (Single-DIN) or a 4” tall (Double-DIN) aftermarket radio into the original vehicle dashboard. This dash kit makes radio replacement simple and comes with a pocket that is installed below the 2” radio to fill the extra space in the radio opening, which can be used for storage. The pocket is not needed when installing a 4” tall radio. The dash kit is painted scratch-resistant matte black to match the original look and feel of the vehicle’s dashboard. Installing an aftermarket radio can upgrade the sound quality and provide additional features the original factory radio couldn’t offer but requires this dash kit to make it fit.

  • Two sets of our 86-9001 radio removal tool are required to remove the factory radio from the dash
