William David Simpson Posted January 21, 2023 Share Posted January 21, 2023 I have a navigation update on USB that I got from Lexus for our 2011 RX 350. Is it absolutely necessary to have a Lexus service department do the update or is there some way I can do it myself? Quote Link to comment Share on other sites More sharing options...

In the CT (2017 with ML audio, sunroof, leather (synthetic) and all the extras available here) we have it is far simpler: Car is not turned on - take out the old microSD-card - insert the new microSD-card - turn on the car. Updated navigations system (2021) functions after about 20 minutes with car turned on. Have not updated since as the navigations system in Lexus is not worth using; often tells you to follow longer roads and sometimes against one way streets. Any smartphone has better navigations system and with completely free updates except for handing info about where you are while using the navigation over to Google. Most people do that anyway. Apple system is not better, also steal all the info available whenever using your phone. Quote Link to comment Share on other sites More sharing options...
