Assuming you are in the U.S., your navigation system can be updated by a Lexus dealer using a master DVD and the proprietary navigation update tool through the USB port.  Take a look at http://www.lexusnavigation.com/what-to-order/

Mine with ML (2011 IS350 F) (Oz model)

2 small holes either side of clock panel under GPS.

Insert the 2 screwdriver looking pin tools from the boot tool kit and press in to release spring clips  and work until panel pops out. 

Go to info button on side of GPS, maps, and there will be an eject button.

Remove Navi DVD. Replace with newer version.

Wait until it loads up. Test. Then replace clock panel.

I got my Oz DVD from this site.
