Hello all, A new RX350 driver here! Loving my lexus so far. Question on how to update the navigation maps on the car. I understand that from 2010 onwards lexus introduced hard drive based navigation system (generation 6, i believe). How do i update these maps? I know i can just take it to the dealer, but I am looking to save a couple of hundred bucks here. Has anyone done an update on the maps themselves? Where do we buy the upgrade dvd/usb? What do you recommend? Thanks!
