I just purchased an 01 ls430 with 34k miles. Everything is perfect, but all voice commands (from the manual) are not recognized so it just responds with the " Voice command not recognized...please rephrase your command" (That last quote is paraphrased, but you get the idea.) I have the display on the correct screen while attempting this, and I am pushing the correct button on the steering wheel, left side behind the volume controls. My son is a ASE cert. mechanic for Toyota and I had him check it out, but could not find the problem. The system needs an update since it is running the original version DVD, but this should not render the voice commands inoperable. So, #1: Does anyone have a similar experience and a possible fix? and.... #2: A FACTORY source for the proper update for this generation nav. system? The dealership I purchased it from (not Lexus) unwittingly provides a 60 day full warranty but I would like to make sure they don't screw up this car looking in the wrong place and destroy more than they fix! Any help is greatly appreciated!
