METRA (99-3018S) CADILLAC CTS 2008-2014

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 easier and includes the necessary Axxess® data interface needed to retain the factory climate control functions. A pocket installed below the 2" radio to fill the extra space in the radio opening is included, which can be used for storage. The pocket is not needed when installing a 4" tall radio. The dash kit is painted silver to match the original look and feel of the vehicle's dashboard. Modifications to the factory dash are required to use this dash kit, and instructions are included. 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 and interface to fit and work properly.
