I have a 2003, with version 6.1, Press Menu, when the screen comes up with the DVD button in the upper right corner.
On the next screen, Press the upper left corner, lower left corner, upper left corner, lower left,lower right corner.
A menu comes up.
Press OVERRIDE until you hear a beep. Then Back.
I have to do this while stopped. It has to be done each time the vehicle is started.
I have been told to be careful, the other menu choices can reek havoc. So only use the Override.

Thanks for your response. Unfortunately it does not work on my LS430 2005 which has the 7.1 version of the map data.
After pressing the DVD button, the screen does not respond to the pressing of the upper and lower corners.
Any more ideas?
#56 of 91 Data Read Error

When I turn on my ignition, the navigation system has a message saying "Unable to read data. Check to see if map DVD is correct". If I try to go into the maintenance screen, I get the same message. All the navigation buttons beep, but dont work. What does this indicate?

I just took the DVD out and the system know I removed it. It knows when the drive door is open or closed. I can read the text file on the DVD from my laptop. It says that it is 2001 ver.1. Is it possible that the DVD is just too old? It worked fine up until 2 days ago. My car is a 2003 Lexus LS430. Are all 430s voice controlled?

.... the DVD should continue to work as it is not time limited. You can identify the source of the problem by borrowing another disk (if possible). If your system works, then the DVD may be scratched or something else with the DVD itself.
If it still doesn't work, the drive itself needs to be looked at for cleaning or replacement.

I think I have narrowed it down to being the drive. Do you have any recommendations on who can clean these thisngs?
#60 of 91 Try your local stereo shop.

You could try blowing it out yourself, but you may knock the read head out of alignment. A good local stereo shop can repair it no problem I would think.
You could get a used replacement drive (cheapest option) or a new one from the dealer (very pricey) or hunt one down on the internet, new or used.
#61 of 91 Incorrect NAV routes
May 20, 2009 (4:19 pm)
I've had a problem with my NAV in my 2001 LS430 that occurred after a data update. It was not fixed by the subsequent update or replacement of the NAV ECU (computer). All functions seem to work except the system suggests crazy routes. For instance, it plots a route from San Francisco to Lake Tahoe that correctly chooses I-80, but at one spot it directs me to go off the freeway, drive 20 miles down another road that runs more or less perpendicular to I-80, turn around, drive back those 20 miles and return to I-80 at the same intersection where I left I-80. There are many other examples, including selection of a minimum time route that the NAV predicts will take 1 hour longer than when I select maximum freeway driving. I have no avoid points programmed and my settings look OK. The GPS works fine. Has anyone else had such a problem?
