The optional Alpine Premium Sound System adds HD radio and a 4.3-inch touch-panel display, and it provides for up to three amplifiers: front, rear, and subwoofer. But as with any Scion product, that's just a starting point. Buyers can order from more than 40 dealer-installed upgrades and accessories, as well as hundreds of aftermarket parts. Many dealer add-ons for the 2011 Scion xD are cosmetic enhancements, but they also offer a wide range of TRD performance accessories—including items like quick-shifter kits, larger brakes, shorter springs, or a performance exhaust system.
Oddly, considering the xD's extensive features list, it doesn't include a Bluetooth hands-free interface, and there's no factory Bluetooth option; it's only available as an add-on.
