I have been trying to find out whether the 2013 will be a new design or just a slight update. I am ready to buy a Highlander Hybrid but really want the Entune. I had heard that this might be avail. for the 2012 in Spring, which I would buy. However, if the 2013 is going to be a major update, I would rather wait for this (~Sept. 12). Does anyone have any info? Thanks!!
