My wife drives a 05 GX470. Is there a way to disable the caution message (i.e. Caution: Drive safely and obey traffic rules...) that appears on the navigation screen every time you start the suv?
View 5 RepliesI 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 2004 VW Phaeton.
Today, the sound system failed, then shortly after, the navigation system failed.
On the console, if I press any map/navigation buttons, the error message "Navigation System Unavailable" is displayed.
If I press an audio related button, the error message "DSP system is unavailable". I took it to a private vw repair shop and a vw dealer. What was causing the issue.
I am now headed to a vw dealer with certified phaeton tech. I looked towards fuse issue, but they appear to be ok..
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?
View 1 RepliesI just realized that I should be hearing the nav system giving me audible turn notifications. And I haven't been getting them. I have a destination entered, and am in the middle of being guided.
Having the audio system on/off makes no difference
I have the voice guides turned on (via Menu screen)
I have the voice volume set at 7 (via Menu screen)
Turning the speed-adaptive volume on/off makes no difference (via Menu screen)
I am on what seems to be the original DVD disc (v3.0?) that came with the car
I have what appears to be a dealer/aftermarket installed rear entertainment system (not OEM)
So:Does the nav system audio have it's own speaker and dedicated channel in the ML amplifier? Or perhaps it's own amplifier
I 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.
I bought a 2003 GX470 a couple of months ago and love it. It was a good upgrade from the 98 Land Cruiser I had a couple of years back and much better than my recent X5. Even though it runs great right now, I have one issue bugging me.
The Navigation unit hasn't ever really worked. Actually, it works, but since I bought it has used the secondary system which calculates location based off direction and speed which is only accurate if driving 50 yards or less - even after calibration
I found out how to get into the secret menu and looked through the settings. When I go to the screen which shows connected satellites, it says "Ensure nothing is blocking gps reception." I've tried a couple of resets, but nothing seems to work. I looked up where the antenna is to see if the connections is loose, but the only reference I found said it was on the rear glass. Unless integrated into something, I don't think it is, though.
The system still runs a factory 2003 disc for maps which is Gen 3. I tried a used 2007 map disc which upgraded the system, but didn't work. It gave disc errors so had to go back to the 2003 one. I haven't had a GPS signal since the day I bought it.
I have a 2003 GX with DVD & NAV. The DVD gives me a message on the rear screen that says "Disk Check" and then never plays the disk. I tried multiple disks and am pretty sure the DVD unit is toast. Looking forward to replace the DVD unit in the center console?
View 2 RepliesNew owner of previously owned 2008 LS600hL and it has the recurring "PCS not available now" dinging message and i want to disable it for now. Upon researching it i found that it should be under the steering wheel presumably next to the TPMS reset button but I am not seeing it. The location I was expecting it to be (to the left of the TPMS reset) actually has two wires going into what looks like a blank plastic cover plate but no button.
View 5 RepliesI have a 2006 RX400h. On 3 occasions I've been stranded. The car won't start and I get an error/message Shift to P when Starting. However I am in Park. It's coupled with a Check VSC System warning. Service department says I have just drained the accessory battery, however nothing is being used other than standard equip such as lights, dash etc. I've had all batteries changed in the car over the 4 years I've owned it. Is this usual?
View 14 RepliesPast couple of days I've had a warning pop up for "Check lights" sometimes even before i have turned them on although I do have arrive depart set to activate. On looking around all seem to be OK apart from maybe 2 leds within the tail lights. It does seem to go out within a couple of mins of actually setting off as well so clearly somethings sorting itself out.... What to check next? they seem to be working fine, I can see them autolevel when I pull up behind a car and the car settles on its suspension etc.

View 5 RepliesI have Lexus 460 LS L 2007. Few months back changed the battery and every thing was ok. 2 months after I had problem in the sound system ( radio and dvd ) which was on and off. One month back suddenly I had all the warning lights in the dashboard on with massage saying that that the brake system is malfunctioning and check the ABS system.
I took the car to LEXUS dealer and they reprogrammed the computer abd then every thing went back to normal and the problem fixed. Two days after I had these warning lights again with the same massege. I do not know what to do ??
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.
How to disable the Lexus Link system? I recently purchased the overhead console with the one that has the sunglasses holder. However, now I get the Lexus Link error every time I start the car. How do so on the GS?

View 3 RepliesPage 575 of the manual that came with my 2016 GS shows that the owner can disable the smart access system, but I cannot find the setting. It ought to be with the page of locking settings but I do not see it there.
View 3 RepliesI have recently decided to not renew any XM services on my 13 GS. One unintended consequence of that decision seems to be a surprise. My slow start of the navigation system is gone. The system starts up instantly every time. I have observed it for 4 days now, and not a single slow start. Not sure if the problem is in the XM receiver, or the way the navigation tries to consume the XM data services, but it's definitely related to XM.
