@srqboater, There is a fair amount of discussion on this topic that you can access using the "Search" command. There has not been any official new software releases since June 2012. Chances are you already have the most recent version, and there is a relatively easy way to check. See this thread, for example.
P.S. The forum you originally posted in is for Forum Software discussion, not the car's software. I am moving your post and this response to the Fisker Karma forum where it is more likely to get better answers.
