A moderate facelift for 2005 gave the Navigator a kinder and gentler appearance, more like a luxury vehicle, less like a truck. At the same time, the Navigator got a small boost in power from a new 5.4-liter, single-overhead-cam V8 with three valves per cylinder and variable valve timing. It's paired with a six-speed automatic transmission that responds to varying driving situations and contributes to a satisfying driving experience. This combination yielded lower emissions as well. There are no major changes for 2006.

Safety features include canopy-style air bags, designed to offer head protection in a side impact or rollover, and a sonar-based Reverse Sensing System that can help warn drivers of an object (or a child on a tricycle) immediately behind the vehicle whenever shifting into reverse. AdvanceTrac stability control with Roll Stability Control, which comes standard, can help the driver maintain control in an emergency handling situation.

Navigator's cabin is attractive and comfortable. Even the third-row seats are relatively comfortable for adults. When it's time to haul cargo, simply press a button on the keyless remote and the power liftgate raises, then walk up to the rear of the vehicle and press a pair of buttons and the third-row seats glide down to reveal a perfectly flat cargo area.
