Regarding GPS/Navigational system for 2003
Range Rover-
from wiki
early US specifications -2003
the vehicle does have a navigation system w/ voice activation. However I wonder how advanced it was since there's many units available as after market upgrades.
The design has a
monocoque (unibody) construction with four-wheel independent
air suspension. Air suspension allowed variable ride height and achieved similar
axle articulation to the previous
live axle design. This retained off-road abilities while improving on-road performance.
[6][7][8] The new Range Rover's introduction in early 2002 as a 2003 model for the North American market resulted in the Range Rover and
Ford Expedition (also new for 2003) being the only two SUVs in the
full-size sport utility class with four-wheel independent suspension systems at that time.
Early US-specification Range Rover included air conditioning with tri-zone climate controls with interior air filter, power tilt/telescopic leather-wrapped steering wheel with radio controls, cruise control, memory system, leather upholstered twelve-way power driver seats, ten-way power passenger seat, power sunroof, a premium sound system with six-disc CD changer, navigation system with voice activation, rearview camera, wireless mobile phone link, universal garage door opener, and outside-temperature indicator. Options included 14-way power heated/cooled front seats,
DVD entertainment system, and upgraded leather upholstery.
