Navigation Update On 2010 Rx350

[prady16]

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!

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).
