xvipx Posted August 17, 2011 Share Posted August 17, 2011 I have an 02 es300. I am currently using navigation disc version 4.1. I know that 7.1 still has the ovveride option because I burned a copy and it let me do it. The burned copy doesn't work well as the navigation randomly doesn't recognize the disc so i switched back to the oem disc. I heard that after version 8.1 the navigation loses the option to ovveride and it is gone forever if u try to switch back to an older version. I want to know if anyone has upgraded to 8.1 or later and still has the override option. I am considering the newest version 10.1. Quote Link to comment Share on other sites More sharing options...
branshew Posted August 19, 2011 Share Posted August 19, 2011 Interesting that you were able to go backwards from 7.1 to 4.1. I have heard that you can't go back to a previous version once you have upgraded.
