Passat (B6) :: Navigation Not Showing Correct Vehicle Location
Sep 27, 2012
I got this problem that just seems to have surfaced within the past week. The first time I noticed, I started the car and the navigation showed my position about 12 miles away in the next town over. Now its been doing the same thing nearly every time I start up the navigation. I can correct it sometimes by going into settings/position on map and manually moving the cursor to my correct location. I say sometimes it works, because 50% of the time I can move the cursor to the position I'm at and it will then work just fine but other times the nav will have my heading completely wrong (I'm going north, but nav has me going south) and it will not correct. Sometimes it will just slowly drift off my real position and eventually it won't even be on a road anymore.
Tonight, no matter how many times I tried to correct the nav by moving the cursor, it kept my heading well off of where it should be, practically 180 degrees from the way I was actually going. So as soon as I started moving again the maps would be totally off.

The "car" symbol on the nav screen seems to lag the actual position by up to 1/2 block.... when I make turns onto another street, for example, the map will sometimes indicate that I am turning into the block itself (instead of the street that I am on), and about 1/4 mile later, it will mysteriously "shift" the car location back onto the correct street.

My Nav system was working okay (the Treg is only 2 weeks old), and yesterday it kept showing me in the wrong location. The sky was heavily clouded and we were having heavy rain. Does the weather affect the system's ability to function properly? Do you need to calibrate it or is there a way to reset it?

The navigation system on my wife's 04 seems to be miscalibrated. It says she is on one street when she is on a different one. Is there any way to fix it?

Driving on my original tank from dealer today from Upstate NY to NYC. On the way my C had 4 bars to begin then went to 3, then 2 after about 90 miles of traveling at avg of about 55mph. I watched the cruising distance go down to 1 but I still had 2 bars on my fuel gauge (and my crusing distance was conservative compared to my mpg reading the whole trip, which was hovering around 58mpg).
The gauge went from 2 bars to one flashing bar in about 1 minute. I pulled into a gas station about 2 miles ahead and put in about 5 gallons... this put the fuel gauge up to 3/4s or about 3 bars above the halfway mark. What gives? I know there are fuel gauge issues but I thought with two bars I would have had plenty of time before I needed to fill up on these roads with these mpgs.

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 2013 Accent and have installing driving lights. I am looking for the correct high beam wire on the driver's side on the headlight assembly. I will then run this to a relay so that when I turn on my highs, the driving lights will come on. I have tried to locate the correct wire but the one wire that is hot when the highs are on, is still hot when the car is off as well as the lights.

I have all functions turned on inside menu options. I have Sirius xm subscription and they told me it's not a service they provide for Lexus. So I'm thinking its a service from Lexus, is this true ?

We just purchased seemingly well cared for 2009 Avalon XLS. Navigation system is showing a DVD error (unable to read). First we thought it was missing the DVD then we discovered the DVD port in the truck and through some trial and error got the DVD (#U52) out. We are proceeding with the logic that the DVD is bad.

I have a 2013 RX with the 'latest' navigation update. My 'home' icon for a while was a red circular looking thing. But without me doing anything, for a while I got/had a 'house' icon showing for my 'home' point on the map. It has since disappeared. It is now that red circular thingy again but with a number 2 in it?

I recently got a 2014 Lexus GS F-Sport, fully loaded. I made a dumb mistake of taking my car in to a shop to have my roof vinyl'd black. And so, they also had to blackout the shark fin antenna on top. They recommended painting it metallic black as it wouldn't have looked good wrapped. So I agreed without knowing. After painting and taking the car home, I noticed the Navigation was off and my GPS was showing me going in a completely different direction. I have calibrated it so many times and it stays on course with me for about one block then starts going off into a different direction on its own. Will removing the paint fix this? Is this something the Dealer has to handle, and if so, charge me for it?

Is there a simple way to stay on the Audio screen instead of showing the Navigation map? If I hit Audio it ends up going to the nav map after about 10 seconds. I don't want to turn off the screen completely.

Problem with GPS not showing your proper location. I did get window tinting done but with a film that is not suppose to interfere. Also got a clean air sticker I installed on my windshield up by the rearview mirror. This lets you drive in the hov lanes in UT with only one person in the car. Couple of questions, where is the gps antenna and how can I check the signal strength? couldn't find it in the manual. Also, the car is 3 months old and this problem just started recently.

Just installed the Vaistech iVic unit yesterday and everything seemed to function fine, but noticed once I started driving today that my Navigation unit was off. It still operated and tracked movement OK, only the maps were about 10 minutes away from where I was actually located.
I've turned off the car several times since, and also took out the Navigation disc and re-installed but it keeps putting me in the same wrong place, This all happens in the normal standard Lexus modes.

Vehicle: 2009 Toyota Prius Base ... Recently my car started showing the master warning light along with the temp warning light on the navigation screen. After opening the hood and inspecting, there is a coolant leaking from somewhere. Took it to the dealer and was told there is no leak but a bad/blocked coolant tank assembly. Question is, if I bought the tank myself for under $1k, could I replace it myself? What would be involved besides replacing coolant? Do I need to get the air out of the lines? Etc.

3 weeks in shop and still no end in sight regarding all the TSB and warranty work. One fix seems to lead to a new problem. Service guys are nice, but it sure is taking long. They thought it was nearly ready to go, but the latest error message showing up tells the driver to "put the vehicle in P" while driving.
