I have a '12 PHV (base) and went into the dealer today to get the supposed 2.2.0 update for Entune. Well, they updated it, but when I checked the version it was 3.1.0! I don't notice much of a difference, but my text messages finally work! I guess some other bugs are fixed as well. I still have to tether my iPhone 5 to the car in order for Entune to work (grr, Apple!). However, I don't have to tether in order to get a notification that I received a text ("Text message received"); the system even reads the text to me. You have to turn the notifications on your phone. The night time mode for the navigation is also automatic now (whereas before I had to manually do it, even when I select automatic!). The navigation also seems faster to load and navigate. Anybody else have the update 3.1.0? You have to go to the dealership to get it done. Mine was completely free. What are the exact updates? The service personnel was unable to tell me.
