Prius (Gen 3) :: 2010 IV Navigation Unable To Read Disk
Mar 25, 2013
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..

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.

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] ......

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.

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.

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.

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.

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?

My 2010 Prius, package IV is only 2 1/2 years old, but I'm at 46K miles.
My factory NAV system has worked fine, but last week when I tried using it, the display said "Map read error", or "Can't read map" (something like that). I ejected the map disc (ver 8.1), cleaned it, reinserted, and got the same error.
My friend also has a '10 Prius, so he let me try his disc. He's got ver 9.1. When I loaded it, the map came up on the display, but the system locked up when I tried to do anything. I had to restart the car, but when I tried again, the same lockup happened with his disc.
Is there anything special I need to do when loading a new DVD map version? Is there any chance it's NOT the actual head unit that's now bad? Is there any chance my dealer would cover this even though I'm over 36K miles, but not over 3 years?

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.

Getting "Maintenance Required" on Display ... How to Read the Code and diagnose? Is this just a oil change or what? I wish the technology car was more technical. Wish it would actually tell me what the prob was. I have a 2012 Prius 3....

I just purchased a Gen III Prius II (I am a Honda Insight convert). The question I have is... Is there a way to change the Climate Control Temperature and the Outside Temperature read outs to Celsius instead of Fahrenheit? I know pressing the MPH/km/h button changes the the speed, distance and fuel consumption, but not the temperature read outs. I prefer Celsius as that is what I was raised on.

Since I purchased my 2010 I've never been able to use EV mode. I know it's just a novelty, and actually hurts gas mileage (due to the need to convert gas to electricity to recharge the battery), so I haven't lost sleep over this, but it is somewhat annoying.
Is there a known problem with 2010s and EV mode? No matter how gently I apply the accelerator it pops out into ECO mode again almost immediately with a message like "insufficient charge" (or something like that), even if the battery is near full charge (I've never seen it fully charged).

As I had two extra keys from my last Prius (totaled 2010), I took them to the dealer to get them programmed - they spent gobs of time, but could not get them to register. They verified they were the correct keys - but in the end, could not get through to Toyota's higher level tech support to troubleshoot it....
They said they'd try again on my first service. Why there would be an issue programming extra keys???

I have a 2010 Prius and have been driving several for the past 7 years.Yesterday, I was driving on the Expressway at 60 mph and all of a sudden I was momentarily stuck at 60 as if I was in Cruise control which I wasn't. Gradually, I was unable to accelerate when I pressed down on the pedal, lost speed and cruised over to the side of the road as if I was out of gas which I wasn't. I shut the engine off, waited a minute and started up again. I continued on my journey without a problem. When I reached my destination I shut down the engine and re started 4 hrs later and drove home 120 miles without a problem. What is the cause of this and is it still under warranty. I have 50,000 miles on the vehicle. May I add, this is the first problem ever encountered.

There must be a way to "turn her off" but I have not found it in the book. When I want to "cancel" the directions being given, what's the secret?

I have a 2010 prius with the navigation package in the last month the compass goes berserk and the the navigation gets completely lost. I have done the recalibration and it may work for an hour or a day then just start wondering.
The xm radio works fine and when I get into the system check page by pressing info while turning the light switch from off to side lights four times all the systems say they are OK and the gyro voltage and direction looks good. This problem is with the original map cd and the versionb11.1 cd.
