The DVD-based navigation system is state of the art, with a 7-inch, touch-screen, dash-mounted VGA display. It is voice-activated, with a single disc mapping the entire continental United States. There is an off-road mode with elevation contours that can guide to a destination, and also track where you have been, to make it easy to return to your start point.

In addition to the usual trip computer functions such as fuel consumption, range, speed and the like, the Range Rover's instrument panel has an interface that shows what the wheels and suspension are doing and direction of travel. Drivers can see front wheel position when slogging through muddy ruts without getting out of the car.

The premium Harman/Kardon surround-sound system boasts 710 watts and 14 speakers. It can be controlled by voice command, steering wheel controls, or the touch screen. The telephone system integrates the owner's mobile phone with the car, allowing hands-free operation and voice commands, either by placing it in a cradle or using wireless Bluetooth technology.

The optional entertainment system includes a wireless remote and pair of headphones. Auxiliary input jacks in the base of the back end of the front center console allow two rear-seat passengers their individual choice of diversion, whether it's watching different videos or listening to separate CDs, while the front seat occupants enjoy their audio selection from the stereo.

Head- and legroom are unchanged from the '05. Seats are big and comfortable, firm and supportive, with adequate side bolstering and lumbar support. New for '06 are articulated front seatbacks with the upper half power-adjustable independent of the lower half. Headrests are comfortable. Rear seats are also very comfortable and supportive with lots of room. The large, front-seat head restraints block much of the forward vision for passengers in the outboard rear seats, however, which might be of concern to people inclined to motion sickness. Four cupholders are adjustable and accommodate many different sizes of bottles and cans.

Carrying a lot of gear is no problem. The Range Rover's tailgate is divided horizontally with a shorter-than-traditional bottom half to ease loading and unloading. That bench-like lower half was designed to support the weight of two adults, making this a perfect vehicle for tailgate parties, or for pulling on a set of waders, or for a quick picnic lunch, or any of those other times you might want a tailgate, often good, memorable times. The '06's cargo area is roomier than the '05's by almost 13 cubic feet. The rear seats are split 60/40 for versatility when moving cargo and people. Luggage hooks on the floor of the cargo area are designed to keep items secure. The full-size spare tire is stored in a well under the cargo floor.
