prady16 Posted June 1, 2015 Share Posted June 1, 2015 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! Quote Link to comment Share on other sites More sharing options...
VBdenny Posted June 3, 2015 Share Posted June 3, 2015 There is an Micro SD chip installed in the dash which has that data. You can remove it like from a camera and that is where the map data is stored (from what I've read). Quote Link to comment Share on other sites More sharing options...
