Metra 99-7520B aftermarket radio installation kit for Mazda Cx-7 10-12 . 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 comes with a radio 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 designed 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.
