This dash pocket has been designed to be used when replacing a factory 4” tall (Double-DIN) radio with a 2” tall (Single-DIN) aftermarket radio into the original vehicle dashboard or when replacing the original factory pocket. The pocket makes radio replacement simple by filling the extra space in the radio opening, which can be used for storage. Installing an aftermarket radio can upgrade the sound quality and provide additional features the original factory radio couldn’t offer but requires this pocket to make it fit when installing a Single-DIN radio.
