Many newer cars come equipped with built-in navigation systems, and drivers of older models often keep a third-party GPS navigation system handy to help them get from place to place. A recent J.D. Power and Associates study found that more and more drivers are relying on their smartphones over the other options to provide them with directions. Approximately 46 percent of surveyed drivers indicated they would prefer an interface that integrates their phone navigation system with a centrally located screen in their vehicle.

"Manufacturers of navigation systems face a serious challenge, as smartphone navigation usage continues to rise and gains preference among vehicle owners," said Mike VanNieuwkuyk, executive director of global automotive for J.D. Power and Associates. "Free apps, up-to-date maps and a familiar interface allow for quicker routing and improved interaction, including better voice recognition."

Drivers who would prefer to use their smartphones may think they can only buy newer used cars that have connectivity options already built in, but they could soon have more options.

Technology company Delphi recently unveiled its new Connected Car devices at the 2013 CES convention in Las Vegas, according to AutoBlog. The device plugs into the on-board diagnostic system (OBDII) port in any car, integrates with the on-board computer and then gives the driver a few new options. After downloading the accompanying app, the driver's phone can act as a key fob, providing remote start, locking control and a panic button. This is the first step to giving drivers similar technology in older cars to that which is included in new models.

Shoppers in the market for used cars can head to New Jersey State Auto Auction, which carries a wide selection of makes and models. Every vehicle on the lot is CARFAX certified, so even if a car doesn't have a built-in infotainment system, drivers will know they're getting a reliable ride.
