Nissan introduced the Platinum Reserve trim level for its Armada for the 2018 model year. Designed to be the top-tier offering, the Armada Platinum Reserve features all the bells and whistles including dark chrome exterior trim, dark grey skid plate and tow hatch cover, two-tone leather-appointed seats, interior trim with unique stitching, and 22-inch wheels and tires. But, and this is a big but, it still includes Nissan’s outdated infotainment system and driver information screen.
