Connectivity and customization for the 2012 Chevrolet Silverado

Heated and cooled seats, a special White Diamond Edition paint job and a new navigation system are among the upgrades for the 2012 Chevrolet Silverado.

Both heavy-duty and light-duty versions also get the option of a Wi-Fi system, installed by the dealer, and new front-end designs.

For 2012, the pickup will have a chrome mesh grille with a chrome surround on LS and LT models, while LTZ grilles will have body-color surrounds. LS and LT models will also get a silver-colored lower bumper fascia and a new set of 20-inch chrome wheels.

Four new colors are added to the palette for regular and HD grades, and a few new interior combinations are offered.

The White Diamond Edition, available in LT or LTZ trim on the standard-duty truck, has a white exterior, chrome mirror caps and door handles, and body-side moldings with chrome accents on LT models. The White Diamond LTZ gets the Z60 high-performance suspension and 20-inch wheels, with chrome tow hooks and exhaust tips.

The new nav system uses a hard drive for storage instead of discs. OnStar continues to be standard, along with automated crash response, satellite radio, Bluetooth and USB connectivity. Chevy Wi-Fi turns the truck into a mobile hot spot, reaching distances of up to 150 feet from the truck. Both regular and HD Silverados get the upgrade.

A new Custom Sport Truck package is offered on the half-ton version for 2012. It celebrates the 45th anniversary of the first custom package of 1967. The group includes the 5.3-liter V8, a heavy-duty trailering package, a locking rear differential, fog lights and a few more odds and ends. It's available nationwide on extended-cab models and on crew-cab models in select states.

Towing has been bumped up on HD models, from 17,000 pounds to 18,000 pounds, while fifth-wheel towing and payload have also increased.
