Lexus SC430 :: 2002 - Navigation Reads - No Disk Detected
So out of the blue while driving, my navigation goes out into a blank grey screen. I took it in to one Lexus dealer and they thought my disk was bad. They said I should just order the new updated one.
I wasn't all that confident that the disk was the problem so I took it to another dealer (both were lexus), and they said I my computer was bad on the nav system and it would be $3000 to replace it unless they could pull it out of another vehicle, then it would be $1800. So my problem is, I would like to try the disk obviously first to see if that will solve the problem, but I don't want to shell out $300 and have it not work, and then learn it was the computer that was broke.

Prius (Gen 3) :: 2010 IV Navigation Unable To Read Disk
The 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 RepliesLexus RX 2004-09 :: Navigation System Giving Message - Insert Correct Disk
I was playing around with the navigation system of my 06 RX400H because I read about the motion override online; however I was being stupid and chose the wrong option under the "load" menu, so the navigation system kept telling me "insert correct disk. ". Hoping that I could find a simple "reset" option there, I was playing with the diagnostic mode quite a bit. One setting allow you to select the navigation unit start up logo between Toyota, Lexus, and None. There is another interesting option called "car setting" don't know what it does.
Seemed like it let you toggle between a numerous of settings, I remember one being 9001X4WD or something. I didn't know what the setting does and accidentally changed the vehicle setting for my navigation unit. After confirming the edit, I realized that the mapping for all the buttons on my panel completed changed! First of all the map button (which wasn't working at the time because I had the wrong load option) became the "Audio" button that is similar to the audio button on my other car, 06 IS350, it showed me all my audio presets and I could choose using the touch the screen (normally this feature is disabled for RX400H).
I realized I might have screwed up the setting and wanted to change back to the original vehicle setting. I couldn't find much information online, so I figure I probably hit that set button by mistake 2 or 3 times, so I reverted the car code back to what it was 3 selections ago, and bam! My panel buttons are messed up even further! Now I don't even have access to the "info" button any more! I can still get access to the first level diagnostic mode using the "display setting" (display key is mapped to the info button now) then left upper corner + left lower corner method, however I can't change the vehicle code in this mode.
I took the car to a local dealer, and the service tech was like "what the heck did you do" and he said he don't know how to fix this except to replace the whole navigation ECU which would cost thousands of bucks. I asked him it would be as simple as getting access to the onboard ECU memory and rewrite it and he said the data format is Toyota proprietary and the dealer doesn't know how to fix it.
Of course I wasn't satisfied with the answer I got, I took the car home. Following some good information on forums and navigation ECU replace instructions on AllData, I was able to remove the navigation ECU from the car, then took it apart, disconnected the power daughter board, pushed the black reset button(?), and then put everything back together. I have seem people saying this method working and not working, but for me it did work. When I restarted the vehicle, the "loading data do not turn off" screen came on, and after the system booted, GPS navigation is working as usual now. On e interesting observation, before the GPS unit has established a connection with the satellites (took about 2-3 minutes to do so), the default location for the vehicle in the system is somewhere in Washington D.C.
Now I have undone my "load version" mistake. However, without the "info" button being mapped to the dashboard, I don't even have access to the menu where you can change the "car code", so even if I know the correct code now, I wouldn't be able to enter it. also it seems that I was able to reset the ECU when I took it apart, I am suspecting that the setting for "car code" isn't store in the ECU but it is stored somewhere instead.
Lexus ES 2007-12 :: 2008 ES350 Navigation System Outage / Program Cannot Be Read Message
We 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?

Is there any way to replace the stock nav system with something that is easier to use and more up to date and works? I did upgrade the disc and it's still a pain to use. My Iphone does a much better job, is easier to use. Also can upgrading the stock suspension on a 2003 SC 430, I got it a couple of months ago with 24000 miles but would like better handling but would like to keep the ride decent.

Lexus SC430 :: 2002 - Navigation Door Quit Working
My navigation door quit working, tilt function also, and it's stuck open. The Nav unit works fine. Dealer is telling me thousands to replace it - but I suspect it's like the Mercedes dealer where my SL was missing a $10 clip - and they wanted to replace the dashboard... I'm hoping it can be repaired. It makes a little "ping" sound then I turn the car off, but I don't hear the door motor.

I have a 2005 RX330 that is fully loaded (Navigation, Bluetooth, steering wheel controls). About 6 months ago almost all of the technology stopped working. The navigation ask for a repair disk. The bluetooth stopped working. The radio still works, but recently it has been spotty, like you will turn on the car and the radio will not work, and no matter how much you turn the volume up or down no sound will come on until you turn the car off and turn it back on.

Bought a used Prius 2010 last december, Now the hybrid system is shut down and the assumption is that the hybrid battery is the culprit. No codes has been read out of the system but the car has passed 330 000 km so I guess that's very plausible. Have found a used battery from a 2009 prius who the local Toyota service facility says is compatible.

Lexus LS 2007+ :: 2008 LS460 Navigation Displaying Unable To Read Data Message
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.

On occasion the navigation unit will not let me enter a new address. I have the car turned on, in park, and the screen has the address option grayed out. It will let me enter previous destinations but not new addresses. This has been occurring more frequently recently. If I drive for a half hour or so,the address then becomes available again (sometimes it does not). It is not the disk, I have tried a new one with the same results.
