Metra DP-3021B Double Din Stereo Dash Kit for 1997-2004 Chevrolet

In this review the Metra DP-3021B is evaluated as a practical solution for C5 owners who want to install a modern double DIN receiver while keeping factory controls intact. The bottom line: it is for Corvette owners who value a clean, OEM-like installation and simple, mostly tool-free assembly. The kit's single biggest selling point is that it replaces the factory radio opening with an ISO DDIN radio provision and includes useful, pre-assembled components so the dash looks finished and functions like the original.

Key Features

• ISO DDIN radio provision: Lets you fit a standard double DIN receiver, expanding head unit choices without permanent dash modification.
• Pre-assembled cup holder: Retains a practical storage and drink solution so you do not lose functionality after the stereo swap.
• Pre-assembled storage pocket with 12V outlet provision: Keeps the factory 12V outlet accessible for charging and small-item storage.
• Painted scratch-resistant finish: Matches the factory dash color and resists light wear for a neater long-term appearance.
• Car-specific fit: Designed for 1997-2004 Chevrolet Corvette, so installation aligns with factory mounting points and controls.

Who It's For

The DP-3021B is aimed at 1997-2004 Chevrolet Corvette owners who want a tidy, factory-style installation of a modern double DIN head unit. It is ideal for DIY installers who prefer pre-assembled pieces that reduce trim fitting and wiring hassle and for anyone who wants to keep the factory 12V outlet and cup holder functionality.

Those who should look elsewhere include buyers seeking woodgrain or radically different trim textures, or installers who need a single DIN solution instead of a full double DIN opening. Also, if you require a perfect texture match to a heavily worn dash, you may find some finish differences.
