Yesterday as I took off for work, I noticed no map on my nav screen. Below is the message I am getting. This is a 2004 and my guess is the nav has never been updated. I bought the GX 3.5 years ago as a CPO.
View 9 RepliesMy new '07 Camry with 5K miles on it, driving along, minding my own business. The navigation was on as it always is, but not in guidance mode. All of a sudden I notice the screen turn dark and I see this error: "MAP DVD - Unable to read data. Check if map DVD is correct." (see image)
I have never removed the DVD from the drive. It is clean as a whistle. I wasn't on a bumpy road. I tried resetting and cleaning it, but no good.
I just purchase this 07 LS460 96K miles less then 2 weeks ago, everything was working fine for the first few days then the navi screen keeps on popping up this message "Unable to read data, please consult dealer" I did many research on this forum and it seems like it's a bad HDD and I have also read it cost 15k to have it replace and such. I just bought the car and its out of factory warranty with the year and miles....
I see this unit on eBay from this totaled 2010 LS : [URL] ......
Navigation system has been working fine and then today if get a screen that says:
"Unable to read data - Check if map DVD is correct"...
My Navigation started to display a message "Unable to Read Data" and would not display the Map on my Certified 2008 LS460. All other displays worked just fine and there were no other problems with my Navi. This had been an intermittent problem for a while so I decided to bring it to Pohanka Lexus in Chantilly, Virginia. I paid them $130 to diagnose the problem for them to tell me that I need a new Navigation ECU - which at first they quote $15,000.00 I FLIPPED! I let them know that I would deal with not having a map and navigation and got my car back!
When they gave me my car I started it up to see the wrong time displaying on the clock and a message that reads "A program cannot be read. Please consult to a dealer" displaying on my screen. I immediately got my SA out there to look at the message. He tried to tinker with all the buttons and couldn't get the message to disappear so he brought his supervisor to look at the message.
They explained to me that when diagnosing the problem they tried to reset the system by removing by battery and it didn't work (Yeah, Actually it made things worse!!!) and now it is evident that my ECU has apparently completely died (and I find it such a coincidence that it happen to die while in their hands diagnosing the issue). They took the car back to see if they could do anything to get it back to the state it was in when I brought for diagnosis.
Big navigation screen it totally blank. Not able to turn on radio. When you start the car you see Lexus logo, then you get warning text after this text its completely black. Backups camera is working and small screen is working. I looked at Navigation fuse, TV fuse they all look good.
View 2 RepliesThe car has been parked for a few months and i get into it and the navi reads unable to read disk? So I eject it and its perfectly clean. I give it a wipe down just for good measure and slap it back in. after a few minutes and some hesitations it works fine.. Then it happens again like 20 miles away, just goes black and says unable to read disk then comes back on again by itself.. Would a newer updated disk work? I have 90k on it and this is the first time I've ever removed the nav disk, could the lens be dirty..
View 4 RepliesIn sunlight my Nav screen is unreadably dim. Is this normal? I just got this 2005 GX, my first, this month and have not had the chance to compare it to others.
View 3 RepliesJust picked up an '05 with the Nav/ML. Everything seems to work, but the navigation screen is painfully slow to update while driving. Sometimes I will be several blocks (1/4 - 1/2 mile) before it catches up with where I actually am. This doesn't seem normal, but figured I'd ask here... is this normal?

View 1 RepliesI was recently in a rear-end crash. The body-shop presumably disconnected the battery, fixed the rear door, and then re-connected the battery.
Now, however, the Navigation screen just flickers.
If I press Info, Audio, or Climate, the screen is just fine
If I press Menu, Dest or Display it flickers.
(Curiously, if I press Info, Audio, or Climate AND THEN press Display, the DISPLAY is fine)
Took it to the dealer, who said it was a coincidental to the body-shop repair.
If you have Navigation there is a selection inside "weather" to view a weather map. No matter how many times I try all I get is a screen telling me it is "down loading data", but I never see the map. How to view the map?
View 5 RepliesRight now it doesn't chance background shade when at night time, it always stays white.
How to change so that it automatically changes to black when in night time ?
My navigation system just shut off and the screen reads" can not read disk" . Any solution for this problem?
View 3 RepliesWe bought our ES350 used a number of years ago. When we changed the battery, the Nav system no longer worked and a " A program cannot be read. Please consult to a dealer." message appeared. Am I wrong to assume that the loss of power from the battery swap caused the software to dump from the system and there was no disc installed to "reboot" the system? All I need is a disc and the system will restore? If so will an "update" disc work or do I need an original "program" disc?
View 1 RepliesAccording to the navigation manual (attached), the navigation screen should go to the home screen within 5 seconds. But my IS never goes to the home screen without pressing the home button, but it always shows the full screen map. I tried many different things including "Auto Screen Change" setting but nothing seems to work.

Diagnosing different minor problems with my sc430. Tthe lastest one is that my navigation screen will not tilt back so the cover will go over it. It seems like its tilted forward all the way. The screen still works and all. But the tilt button does nothing and its too far out for me to get the wood grain cover to go over it. Is this a common issue? and whats the remedy?
View 10 RepliesCan you customize the Navigation Home Screen? Is it possible to do it on the 2015 Lexus LS 460 ?
I find it strange that my navigation home screen has the dealership name and logo on starting up the car so I figure that it could be set or change.
Is there a video or guide on how to do it? I want to put my family picture as the start up home screen.
At each car startup, after the navigation loads, it eventually settles on the map screen. Would prefer my personally adjusted home screen (the home button nearby the mouse) to just automatically appear on starting the vehicle. Is there a way to do this?
View 4 RepliesI purchased a CPO 2013 RX350 recently and just noticed that it has some scratches in the navigation screen (only seen in certain conditions when black and not under power). I am scared to try any compound on it.
View 4 RepliesIs it possible to turn off the display screen for the Nav system? I mean turn it completely off, so the screen is dark.
