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.
Lexus GX 2004-09 :: Navigation Screen - Unable To Read Data
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.

My 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.

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?

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..

So I have a PCS fault on my 2008 LS460L and brought it to my local Lexus Dealership....They basically insist that the data controller is/may be causing the PCS fault.
In the meantime, I guess the most probable action is to disconnect the data controller and see if the problem goes away.....

View 1 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.

View 4 RepliesFord Audio/Video System :: 2007 F150 - Nav Not Working - Cannot Read The DVD
The navigation in my 2007 F-150 is acting up, saying it cannot read the DVD, and that it might be dirty, remove and clean, etc. etc.
Also, and perhaps an equally concerning problem is that it won't spit the DVD out. It will get so I can barely see the disc through the mouth of the system, but not enough to grab it. I'm going to try and grab the disc as delicately as I can with a small set of grooveless needle nose pliers, but haven't had a chance to try that yet.
It was doing this a while ago, but seemed to fix itself and hasn't acted up for I'd say 2 months now.
For those that have had this happen before, is it as simple as cleaning the disc, or is this a sign of a larger (possible system failure) problem?? Also I should mention that I still have the original map DVD in the truck, and I think I've taken it out once in the year and a half I've had the truck, and that was just in learning how it came out.

I downloaded several mp3 files from Amazon and loaded them on a flash drive to use in my 2011 ES350 audio system. The flash drive is plugged into the USB port in the center console, and CD/Aux is selected to play the files. The weird thing is that although most files play, there is a few don't. There are folders for the non-playing music files, and a file is indicated in each, but after a short display of the folder/file number, the player skips on to the next folder without playing anything. Is there something I can do to get the "silent" files to play?

I was scared and took the next exit turn around and going home. I'm at 41000 miles and out of warranty.
