Lexus LS 400/LS 430 Navigation System

frisco7frisco7 Posts: 5
My LS430 is a great car except for the voice navigation. No matter how I try, speaking in various levels etc. "POI OFF" and "AUDIO OFF" are constant problems along with other voice commands. There are over 300 Lexus published commands of which only a few actually work. Has anyone else had this expertience?

    Has anyone else had this expertience?

    My "expertience" is similar, but different with my "nagigation"..

    I can get POI OFF and AUDIO OFF to work fine, but there are 298 other commands it gets wrong.

    May I suggest, however, that your "expertience" with your "nagigation" malfunctions may be your spelling? JK :P
  • You caught me with my pants down on my spelling. It is embarrassing to say the least, but it seems we are having the same voice nav problem. This is so unlike Lexus. Mercedes and Honda have superior voice systems and the premium car does not. I understand the 2007 LS460 is a better system. LL

    Thanks for having a sense of humor! I appppreciate it. Yes, I think lots of us, pretty much anybody who tries to use it has the problem. I have also heard that the problem is greatly improved in the 07 version. I have tried to memorize the 300 commands unsuccessfully. Trying to look them up on the freeway doesn't work either. The few I know, sometimes work, sometimes not. Eventually, I just push the state-of-the-art button, and get on with it. I appreciate the concept - but it's not yet perfected. When voice dial cellphones first came on the market in about 1997 or so, you had to "say each name" into it in program mode, so it would recognize your voice. I got pretty good at imitating my co-worker's voice when I drove his Caddy, but I was amazed when I got my 02 LS430, that this was no longer needed. Then I was amazed at how it doesn't always work either.......

    I've driven the 460. I want one. That will fix my problem.

    My granddaughter and I have lots of fun giving commands and see what comes back from the NAV lady. We have had a few great laughs. The most success I've had is in adjusting temperature.
  • nvbankernvbanker Posts: 7,285
    Yes, temperature up and down works. I can get guidance stopped, but almost everything else I try to do, gets me POI marks for the darndest things.....
  • I can complain about the voice activation problems all day but the truth is that Lexus left us short on this feature. I have taken it a step further and filed a complaint which is pending at this time. This is my 4th Lexus and the first time I have any problem with any of them. Hopefully the '07 has a better system. If you stay in touch I will keep you up to date on what the outcome of my complaint is. LL
  • I just installed the latest Nav DVD (version 6.1) on my '04 LS430. Everything worked AOK until I tried the secret "Override" sequence, and to my horror discovered that it no longer works!!

    I had previously read that in the LS460 it did not work, and took that as a good reason not to buy one, but I didn't expect that the 430 update would kill it.

    If anyone finds a new secret sequence would you please please post it. Thank you.

    So if there is no override sequence for this update you might as well go out and buy the LS 460! ;)
  • Good point, Pat. I was hoping I would find a reason to buy one. Now you have given me the reason. Thanks.

    My dealer wants $600 to load the latest version of software for my GPS. This is a ripoff since a complete GPS can be purchased for $600 or less, In fact I just bought a very nice GARMIN for $350 for my other car.

    Does anyone know how to get a software up grade for an honest price?
  • I bought mine on-line from (Sewell Lexus in Dallas, I believe) for $288, then installed it myself. There was a very helpful post a couple of years ago explaining how to do the install, in case you have any problem.

    Thanks for you post on an upgrade for Lexus GPS software. I shall check this out. My system dates to Nov 2001 and a lot has changed in Florida since then.

    Cna you provide and direct me to the post on how to install it? Or does instructions come with it?

    Thanks Again!

    When you installed the upgrade software was it done through the DVD player in the dash? I ask this since recently my DVD player got hung-up and needs to have some repair done to it.

    feverhart - install is nothing more than removing carpet in trunk (just roll it to the left side), take off the obvious cover on right side of trunk to expose the unit. Remove the two side screws and tilt the machine up, exposing the front insert slot. Have the car powered up, slide the left little slot cover open (just left of DVD slot) to expose the eject button. Push that and exchange the DVD's. Be sure car is powered (doesn't need to be running, just key in the accessory position) for the exchange - the update will begin automatically and display on the nav screen. Once complete, just tilt unit back down and resecure screws and cover. Your version should now show 3.1 versus our old 2000 1.0

    There are some small changes to map icons and displays, but the voice sounds the same to me (thought someone said the voice had changed). I don't know the cutoff date of the database, but I was disappointed in some of the POI's I looked for that still weren't there - restaurants that have been in existence about a year or so. But others are there. Overall, seems ok, if still expensive. I also have a Garmin Street Pilot III that I use in my other vehicles - they are offering an update to that system and want $150 for one CD (not DVD)and it is for full country.

    End of flint350 post.

    Someone else subsequently added a warning: Be careful not to let the screws drop into the well - they would be very hard to get back out.

    Good luck.

    I have a 2006 LS. Is there anyway to have the Nav system default to the audio view each time the car is started? I really don't use the Nav system very often and would rather not have to switch it manually.
  • nvbankernvbanker Posts: 7,285
    I don't think so.
  • I just got notice from that they have shipped me the Navigation System Update Data Ver 07.01. I had pre-ordered it, for $260.
  • I just installed the new Nav DVD. After MitchellRowe's report that the '08 LS460 no longer asks the driver to agree to drive safely before allowing him to use the Nav system, I was hoping the new DVD (on my '04 LS430) would do likewise, but unfortunately it still has the old Caution screen where I have to touch "I agree".

    The other thing I noticed is that the new system has lost my "Previous" memory points. Aside from that I haven't noticed any improvements yet, but hey I just installed it this morning.

  • I have a 2001 Lexus Ls430,and the screen shows that i am in the middle of the Puget Sound,and the streets have disappeared,I live in Seattle,does anybody have any idea what the problem might be.

    I presume that you have depressed the "map" button at the top of the nav buttons. If your system is working normal and you move the curser/map to another location, depressing the "map" button will return the display to current position. Other than that, I have no other suggestions. Good Luck..
