I just sent this message to Chrysler customer service:
I own a 2005 Chrysler Crossfire Limited coupe equipped with the navigation system. It is my understanding that Chrysler has no plans to release updates to the 2004-vintage map CDs that came with it. If Chrysler is unwilling to release updates, would they consider releasing the firmware source code, data formats, and development tools under an open source (i.e. GPL) license so owners can provide their own updates? If not, would they consider instituting a community developers program so registered users could get access to these? I love my Crossfire and want the same map updates that owners of other Chrysler models enjoy.
I'll post any replies.
