CES 2013: The hottest car tech in Vegas

There was a lot of cool stuff on display at CES. In fact, there was a lot of stuff, period. Trying to find a single standout isn't easy, especially when it is near-impossible to even see everything at the massive event. But there were a number of products and technologies that did get us excited.

Of course, the radio-controlled flying drone Parrot showed is pretty cool, as were balls that roll themselves around. But in the automotive realm, there was notable new technology and gadgets, even without a flying car.

Here's my picks for the hottest car tech at CES:
Autonomous cars with the potential to drive themselves from Audi and Lexus got a fair bit of buzz, and Audi even did demos of a car parking itself with nobody in it. Valets of the world, start looking for work.

Qualcomm showed inductive electric car charging. Currently being fleet-tested in London, the inductive system recharges an electric car that parks atop a three-foot-square pad by transmitting power to a receiver mounted on the underside of the vehicle. No plugs, no fuss. A company rep said it works in all kinds of weather, even if covered in snow and ice.

Digital Light Processing technology, or DLP, allows for more vivid and colorful dashboard and heads-up windshield displays. DLP was showcased by Johnson Controls, MHL, and Visteon, giving a look at car displays of the near future. Johnson also showed a 3D rearview camera,and an onboard navigation system that can update maps and point-of-interest information from a smart phone, rather than requiring a visit to the dealer or just leaving drivers to work with outdated information.

Navigation sales-leaders Garmin and TomTom unveiled new portable navigators and updated traffic services, respectively, but both were trumped by the Magellan SmartGPS. Edging portable navigators as close to smart phones as conceivable, the SmartGPS can provide numerous Internet-based services by tapping a smart-phone data plan via Bluetooth. Where it stands out is being able to download data via WiFi, loading route and points of interest info before starting a journey, without chewing up bandwidth. And it claims to seamlessly share its data and controls with the phone, allowing the user to benefit from local information, such as user reviews for restaurants, when on foot.
