Especially at the base S level, the Altima comes with a few more features than you'd expect. Nissan's push-button ignition system is included on all Altimas, whether you like it or not. Other extras included on the S are the Intelligent Key system, six-speaker sound, air conditioning, rear seat heaters, a trip computer, dual power remote-controlled side-view mirrors, and speed-sensitive variable intermittent windshield wipers. Top SR models get a power driver's seat, wood interior trim, and a few other extras, while options include a Sport Package with High Intensity Discharge (HID) headlights, fog lights, a moonroof, and a rear spoiler, or a Technology Package with a nav system, Music Box hard drive music system, Bluetooth streaming audio, and XM NavTraffic and NavWeather. A Premium Package wraps those audio upgrades with leather seats (heated in front), plus mood lighting, rear A/C vents, and a HomeLink garage-door opener.
Popular Mechanics says that the available nav system's "6.5-inch VGA screen offers one of the better interfaces we've experienced, with intuitive switching between navigation, satellite radio, and Bluetooth functions."
The 2010 Nissan Altima offers some very noteworthy options, but you'll have to pay a lot of you want just one in particular. Cars.com finds that "most popular options are grouped together in expensive packages." They warn that while this method is "fine if you want everything in the package, you may not be as happy when you learn that it will cost $2,150 to add a moonroof to the 2.5 S trim level." Edmunds deems this business practice "a little shady," comparing it to "going to a salad bar and being offered a choice of either dry lettuce or a 4-gallon bucket of Ranch."
Regarding options, Kelley Blue Book draws attention to the "dual-zone climate control system, power moonroof, voice-activated navigation system," and "premium Bose audio system."
