Lac213 Posted April 25, 2017 Share Posted April 25, 2017 Just acquired a 2011 es350. What's the best and cheapest way to update the navigation system. I believe I have an hard drive unit. Quote Link to comment Share on other sites More sharing options...
Lexus_DK Posted April 25, 2017 Share Posted April 25, 2017 It's best if you bring it to the dealership to perform this update. You need the Lexus NAV update equipment. Quote Link to comment Share on other sites More sharing options...
