Turbo Mike Posted December 25, 2009 Share Posted December 25, 2009 I bought the upgraded 7.1 navi disc for my 05 GX470 and the override sequence doesn't work on this upgrade. Has anyone figured out how to override this updated disc? Quote Link to comment Share on other sites More sharing options...

Has anyone figured out how to override this updated disc? I'm pretty sure I've read that once you upgrade to 7.1 or newer the override is no longer possible. You can think the Lexus legal team and the litigious society we live in for that. The only way to bypass after the upgrade is to purchase proprietary 3rd party hardware (prestigious society) or do a "hack". Quote Link to comment Share on other sites More sharing options...
