The 2009 Infiniti G37 draws praise for its extensive standard features list, but reviews read by TheCarConnection.com show that if the basics aren't enough for you, a variety of options are available both as stand-alone features and grouped together in packages.
For Infiniti, 2009's lineup of G37 sedan models is largely similar in terms of standard equipment. Kelley Blue Book reports that all Infiniti G37's are "exceptionally well appointed, [and] even the base G37 Sedan offers leather upholstery, a full range of power assists...[and] steering wheel-mounted supplemental audio and cruise controls." TheCarConnection.com's editors also note that a six-disc, six-speaker AM/FM/MP3 sound system is included as standard fare on the Infiniti 2009 G37 lineup. Kelley Blue Book remarks that "automatic air conditioning and high-intensity discharge (HID) bi-xenon headlights" round out the Infiniti G37's features list.
Moving on to the options list, Road and Track reviewers note that Infiniti's 2009 G37 lineup "can be enhanced with four-wheel steering, rosewood trim, navigation with rearview monitor, pre-crash seatbelts and adaptive headlights." Edmunds adds that the 2009 Infiniti G37 can be outfitted with an optional Bose sound system that they say "is one of [their] favorites, delivering stellar sound reproduction without the intrusion of complicated graphic equalizers or other high-tech sound-tailoring gewgaws." Edmunds also raves about the optional navigation system, which is "one of the best [they've] encountered, with intuitive controls and a clear and attractive display." Kelley Blue Book lists some of the other optional features as the Premium Package, which tacks on a "moonroof, Bose audio system, power tilt and telescoping steering column, Bluetooth and more," while the Technology Package brings "Intelligent Cruise Control [and] adaptive front lighting" to the mix. The Navigation Package for the 2009 Infiniti G37 sedan includes Infiniti's Lane Guidance system and a 9.3GB hard drive for onboard music storage.
