Go to http://www.driveuconnect.com/support/ramtrucks/. Select Navteq Navigation Updates and choose Ram 1500, 2013. It will tell you "Our records indicate you have the most recent map update for your vehicle. Please check back soon for a map update product." That's because they only release updates once per year and the 2013 Rams haven't been updated yet. Probably won't for another 6 months.
