The 2007 Acura RDX sells as one well-equipped model, with an optional Technology Package featuring ELS Surround Sound and Acura Navigation with real-time traffic. For the RDX with the Technology Package, some of the coolest add-ons include a rearview camera, Acura Navigation with Satellite Communication System and real-time traffic reporting, a ten-speaker Acura/ELS Surround premium sound system with a DVD-A six-disc changer and XM satellite radio, and a wireless (think Bluetooth) telephone interface. That’ll push the price up to the high $30s, and probably topple the X3 – putting the Acura RDX close to a 2006 Infiniti FX35 in terms of pricing.
