Don't settle for stock
The console design in the Chevy Spark makes it difficult to upgrade the factory radio, but Metra has the solution. Their 99-3309B package includes the dash kit pieces, wiring harnesses, and brackets you'll need to install a new car stereo. The included dash kit replaces the factory radio dash console in your Spark, enabling you to install an aftermarket single-DIN (2" tall) or double-DIN (4" tall) radio using the supplied brackets.
Keep the good stuff
In addition to the power, ground, and speaker connections, this Metra harenss lets you keep the factory OnStar, Bluetooth, safety warning chimes, and the Retained Accessory Power (RAP) feature, which keeps the music going until your door is opened. Attach the color-coded wires on the Metra harness to the wires from your new stereo, and then you'll be able to plug right into your car's factory radio connector. If you're installing a navigation receiver, the 99-3309B adapter also offers the parking brake, reverse, mute, and Vehicle Speed Sensor (V.S.S.) outputs that you'll need. Warranty: 1 year.
