Chrysler says that its dealers will now be able to activate navigation systems on new or used cars.

Chrysler dealers will now be able to activate navigation functions in vehicles, both new and used, equipped with the automaker's latest Uconnect infotainment system.

Previously, adding navigation to a Chrysler product's infotainment system either required ordering the function from the factory or upgrading to a new head unit. Now, however, Chrysler dealers will be able to upgrade a vehicle's existing software to a navigation system identical to what could have been installed at the factory.

For now, the update is only available for vehicles running the automaker's latest Uconnect Access software, which means that only the 2013 Ram 1500, the SRT Viper and the upcoming Fiat 500L can be upgraded. However, nearly every future Chrysler product will run uConnect access or newer software.

Chrysler says that customers will now be able to choose if and when they want navigation functionality in their vehicle since the update can be made at any point. The automaker thinks the updates will be particularly appealing to used Chrysler buyers.

The automaker's new Uconnect Acess system includes additional functions over the previous Uconnect touch, including voice to text, text to voice and a built-in WiFi hotspot with downloadable vehicle apps.

Chrysler hasn't announced pricing for the navigation add-on from dealers. The automaker charges about $500 for the navigation software from the factory on a 2013 Ram 1500.
