Sorry if this question has been posted before. . . .I was about to buy a new 2013 Maxima because of a huge discouint. I happened to see a 2013 Genesis, and am now considering. The price is about the same for the fully loaded maxima and genesis with the premium package. What would I really be missing with out the tech package? What is the difference in the NAV units? What is the blu link? It says blue tooth hands free phone. I think you can do bluetooth with my iphine with the premium package correct? Looking to buy tonight, so any help would be appreciated!
