TheCarConnection.com found few features missing on the 2008 GMC Acadia.
All GMC 2008 Acadia crossovers come with 18-inch rims, front and rear A/C, and GM's OnStar concierge system with "turn-by-turn" navigation assistance. Higher-end models offer or can be ordered with all the niceties, from a 10-speaker Bose surround-sound stereo to three-zone climate control, a power rear liftgate, a head-up display (HUD), a GPS navigation system, a two-panel sunroof, and backseat DVD entertainment system.
Kelley Blue Book adds that with the Acadia, GMC installs an "AM/FM/CD stereo with six speakers and MP3 capability and XM Satellite Radio” as standard equipment, while available options include "leather seats, ultrasonic parking assist, a DVD-based navigation system and a Bose 5.1 surround sound audio system," according to Cars.com.
In the Acadia, GMC has designed audio controls that are “easy to reach," ConsumerGuide reports, while "the optional navigation system absorbs most audio functions but doesn't complicate their use." This source was more critical of the climate controls in the Acadia; GMC’s design puts them "within easy reach,” but “their pushbuttons are less convenient than rotary knobs."
Mother Proof raves, "the Acadia really has just about every feature you could possibly want, plus some you've never imagined." According to this source, "the interior designers of the GMC 2008 Acadia placed a notch at the bottom of the plastic that will accommodate all but the chunkiest of [shoe] heels."
