If you just have the basic head unit, and you have installed an amp and sub, i would definitely swap it out. The main thing i would want, would be subwoofer level control in that little car. Sometimes you just have a headache and cant take all that bass. Unless you have an external bass knob on the dash going to your amp to control the subwoofer, i would swap it. Not to mention all the other cool stuff aftermarket double din units can do these days.. Pandora, ipod ingratiation, i think some of the more expensive units even dispense Egg McMuffins in the moring PAST 10am
