Omegaman Posted April 30, 2008 Share Posted April 30, 2008 How do you change the screen so that you can use the Telephone Screen and our the Navigation System, while driving ? The Big D: That is a question that has been asked for about 2 plus years now and the bad news is no one has found out how to do it on 2007 or later models. Some have made a hardware modification (entails cutting wires, or adding a switch, etc. which requires removing the Nav screen). I too would like to be able to actually use the nav system (that is my wife from the passenger seat) but after searching this forum and the internet for many many days now, I have found no solution. The problem is that Lexus has either removed the override option (used to be available with simple touches on the screen for older models), or it is accessible through some other means that so far no one has figured out.

ErnieG Posted May 2, 2008 Share Posted May 2, 2008 I have a 2004 LS430 ( I beleive it is Gen 4 system) with map data 3.1. What is the latest data update I can use which will allow me to use the override steps you describe in the tutorials section. Also any suggested places to buy the disk? Any post you can refer me to for intallation instructions? Thx Ernie How do you change the screen so that you can use the Telephone Screen and our the Navigation System, while driving ?

Thx Ernie Hi Ernie, the latest nav software with the override menu is version 5.1, which is pretty out of date, as the latest navigation software is version 7.1. I've sent you a pm with more info, and can send you install instructions as well. Quote Link to comment Share on other sites More sharing options...
