The base model RDX includes most of the essential convenience and safety features that buyers would expect, although it does miss out on some of the more desirable items available with the optional packages. The audio system at this level includes seven speakers, a subwoofer, satellite radio, SiriusXM satellite radio, Bluetooth streaming audio, Pandora compatibility, and auxiliary / USB inputs. Ten-way power adjustment for the driver’s seat and four-way power adjustment for the passenger seat are included, although leatherette rather than leather covers the seats.
