When I bought my Certified Pre Owned 2013, I did not have the LEAF icon as well. I knew about it, because I had it on my 2013 C-Max Energi. As it turned out, it still had SYNC version 3.1.3 loaded. The info on owner.ford.com showed this was the current version, but I knew better. After some discussion with the service department, and some online messaging with the IVT Team on http://fordsyncforum.com/
, they were able to update me to v3.8, which was the most current, and gave me all of the proper "plug-in" features of SYNC as well as other updated tweaks, including SiriEyes.
