Chrysler has revealed a new version of its Uconnect touch-screen interface at the 2013 Consumer Electronics Show, which the automaker claims is the first in the industry to enable dealers to upgrade the system with navigation, weeks, months or even years after the car is bought.

This means that used car buyers with a Uconnect-equipped car can have navigation added to the system if the car wasn't originally ordered with the mapping tool.

The latest Uconnect systems have all the necessary hardware for navigation; they just need to be unlocked by a dealer. Chrysler’s navigation system includes useful tools such as points of interest, visual and audible guidance, speed-limit information and trip planning.

Unfortunately, the new Uconnect system with dealer-activated navigation is only available on the 2013 SRT Viper, 2013 Ram 1500 pickup, 2014 Fiat 500L and newer vehicles.

Older vehicles with Uconnect won’t be upgradable, meaning existing owners without navigation will have to continue to rely on aftermarket devices.

Chrysler is also increasing the flexibility of Uconnect by introducing internet-radio app integration. Building on the existing Uconnect Access, which features security services such as 911 assist as well as text message functions, Chrysler has added a new Uconnect Access Via Mobile feature that enables Aha, iHeart Radio, Pandora Internet Radio or Slacker Radio music streaming with Uconnect using smartphone data.
