Hed hurts are the following. The nav disk is correct, other cars' of the same model 2004 do read it - just checked in friends' car. Mine also read but now after 1.5 years of use it writes "insert correct disk". Also many icons disappeared from INFO screen - only remaining are "Screen Settings", "Telephone", and "Trip Info". And there is no voice through speakers after connecting via bluetooth any more. So what is the price for those components ?

There are 2 modules under the passenger seat in my LX ( model 2004). One box - is where u insert DVD nav disk (I reffer to it as a DVD-player), another box is smaller and it is under the first. I don't know how exactly u call these 2 components, are they both called "nav computer" , or one of them is "DVd -player" while another is a "computer". Anyhow one of them or both in my LX are broken and malfunction. Can u advise how much do they cost ( new oem) - both or separately ? Also any ideas - "why they might start malfunction suddenly after 1.5 years of use while nobody never touched them" - are welcome.

Not really. My car was delivered from the factory and nobody including me never touched the disk or whatever under passenger seat. I even never knew about the existence of DVD-computer there. It started malfunction suddenly after 1.5 years of use. Professional electronicians were right. The head of DVD-player doesn't touch a disk during play, so if nobody never eject the disk from there why must it suddenly malfunction ? Today finally I have understood and proved that the problem is with computer, not disk. Finally I found another car of 2004, inserted his disk of the same version into mine, it doesn't play, then I inserted my disk into his computer and it plays it !!! That is my computer is broken after only 5,000 miles of use without any evident reason.

JimM, did u solve yr problem ? I have similar one but my appeared after 1.5 years of use. Please, see my last 3-4 threads in LX section of this board. Mine tells: "Please insert correct disk" while I never changed and never touched the disk inside.

Some posters here mentioned smooth and quietness of LX/GX. Did u ever drive other SUVs such as Porsche, BMW, Mercedes and how do u compare them? And in general how do u find Lexus sedans in comparison with Mercedes sedans in quietness and smooth ride ?

Can u advise what is the exact list of differences between LX470 - 2004 , 2005 and 2006. I heard 2006 model now on the display where was navigation also shows either TV or DVD ? And HP was increased ? Any changes in the exterior ? May be there is a link to the list?

So no experts here ? My question is very simple. My Nav disk is broken, the hard drive under the seat was detached for some time, now it is attached again. Does bluetooth function somehow depend on the disk and memory of the hard drive ?

Imagine yr Nav disk is broken. U detached for 1 hour the computer with DVD-player ( what u call "hard drive") under passenger seat and then attached it again. What will u miss on the screen ? Shortly, after cutting a power to that module what is erased from the computers' memory? In some cars after det/att a car stereo u must input some code to let them to operate in the normal mode. It is why I ask the question above. In my case I started miss a few icons such as Calendar, Maintenance which appear usually after u push on "INFO" button near the screen. Also my Bluteooth system doesn't operate anymore, devices find each other but there is no sound from speakers. If I find new Nav disk and insert it there instead of borken will everything be restored in the computer's memory and will Bluteooth operate again normally or the disk is not enough and I must input some code or do whatever ? Anybody from experts know ?

I bought new LX in 2004. It was brand new absolutely. Till today it went only 15,000 km = 8-9,000 miles ( I use it rarely). Suddenly after 1.5 years Map disappeared from the screen, and "Insert correct disk" appeared on the dispaly. Nobody never opened DVD-player under passenger seat, I even never knew where it was located. Those of members who are experienced in such things, can u advise " May it be disk's fault, or it's player's head's fault?" I'm going to buy new disk from abroad but it is very expensive, and I have no Lexus service in my city.

Is it possible to play 2004-2005 or 2005-2006 Navigation disk in cars with 2003-2004 Navigation disk factory installed ? I'm talking about normal versions, not about special Updates.

I had " insert correct disk" problem with my Nav system in 2004 LX. The problem appeared after driving it for 1.5 years. I wasn't sure is it problem with disk or the computer itself, so I asked my friend who is electronician in car audio/video. He deattached all cables under passenger seat, opened the DVD-player, cleaned the head. Then puted everything in it's place. The same problem persists. He also told that probably the problem is with the disk because he checked the lazer and told it is OK. I'll try to find another disk. But now after putting everything in it's place some icons disappeared from the screen:after pushing on "INFO" knob I get now only "Telephone", "Trip info" and probably "Climate" ( don't remember 3-rd exactly). Now there is not "Calendar", "Service schedule" and other buttons. Additionally to this bluetooth started have some problems, no call I can do any more, nothing heard from speakers. Anybody knows what was happened with them? Is it some kind of default setting the system returned to ? What is with bluetooth muting calls ? Is it related with NAV somehow ?

I have 2004 LX-470. Never opened factory DVD-player under front passenger seat. After 1.5 years of use suddenly it stopped playing factory disk with navigation files and says that can't read DVD disk. Something wrong with DVD-player or disk ? What do u think ?

According www.lexus.com it seems that nothing changed. Any info about that ? Maybe engine was 225, became 235 hp ?

Why some of you is telling about "Sport against Luxury". I can't tell that Cayenne is not Luxury. Inside it has everything LX has, external design is not worse if not to tell that better. Isn't ? Moreover, despite we own Lexus, the name Porsche is higher than young Lexus. I don't recommend buying basic V6 model of Cayenne, it's acceleration will be more or less same as of LX. You can buy for your wife Cayenne-S ( Turbo S is expensive) with acc. around 7 sec.

Did anybody from LX owners drive Cayenne ? How do you compare with LX ?

When you just start up LX goes to check itself and there is essential noise from fan in front of radiator rotating at very high rpm-s, after 15-20 seconds the noise goes off. But it appears time from time aslo during driving. How often in your case ?

No, it is not like metal rattling. It is like growling, exactly the same sound which happens when you just started the car, similar to that when you push an accelerator and race the car. But it happens in low rpms, not when you race.

I have 9 months LX-470 of 2004 bought in november 2003. Gone only 3,000 km. According manual when you start an ignition you MUST hear noise - the car tests itself, after 10-15 seconds it goes off. This is according manual !!! Unfortunately, I hear the same kind noise very often, not only at the start. It may appear when I push a little ( not race) on the accelerator pedal after say 20-30 minutes of driving, then goes off again. It doesnt't persist, but appear often. It also appears say when I stop and turn of an ignition, and after 5 minutes start again. I thought Lexus must go quiet and very smooth. Is such a noise normal ?

Madness999, Thank you. I bought my new 2004 Lexus in UAE, since in Azerbaijan where I am we have not Lexus dealer. UAE belongs to so called GCC countries, this is how they designated Middle East countries in the Lexus manual. Since they have always summers, I thought that maybe something wrong with this version of the car. For example, there are hundreds of options in my car including bluetooth telephone, front parking alarm, keyless go system, but it hasn't front seats heating. This is because probably they don't need to heat them at all. But here in Azerbaijan we have normal winters also with minus temperatures and snows. If to be exact rear roof a/c doesn't have in my car airflow buttons, I made a mistake. It has only temperature control and fan speed buttons. I don't feel warm air comes from below front seats. In manual is written that it must come from below central armrest panel, but this is except Middle East countries. Just so I'm interested in maybe somebody has the same Middle East version and can answer ? Does your rear a/c heat at all ? With front a/c there isn't problem, it heats normal.

Sorry, but this doesn't help. I have no buttons in my 2004 Lexus. I have control buttons of the a/c on the roof, a little behind the 2-nd row. You can adjust there temperature and airflow directions and e/c. And I have some air diffusors on the roof, there is not any blue or red indications on that diffusors. When a/c in the heating mode the cold air comes from diffusors on the roof near 2-nd and 3-d rows. What Have I to do, to close diffusors in the winter, either not to use REAR a/c in the winter at all?

Nobody knows? Nobody has a Lexus LX-470 ?

This discussion must be closed, I think. Because as you see I asked the question in August and already bought on November 1 new LX-470 of the model 2004. And I'm completely satisfied. Thanks to all.

I live in Caucasus, Azerbaijan but bought my new 2004 Lexus LX-470 in UAE since we haven't Lexus dealer in our country. It has factory installed DVD-navigation system with disk keeping maps of Middle East countries only. In my case it is meaningless and I assume that probably there is not navigation disk for our region at all. 1. Anyhow, do you know which kind disks are available - I mean which regions do they cover, and how to change that disk in the Nav system? 2. Fronf dashboard screen of my car is touch screen display and all controls of Bluetooth telephone, installed audio system and e.c. is controlled by touch screen and thus are electrically interconnected. I want to install additional Sony DVD-changer in the rear and Sony roof screen somwhere at the Toyota ( non-Lexus) or another service center. Do you know, is it possible to control them also by touching the same front screen, if not will they interfere with the existing eclectronic systems such as telephone, audio and e.c. Thanks for the help in advance.

When I set a temperature, say to 25 C in the heating mode in autumn and after that turn on rear air conditioner I notice that cool air comes from rear roof side and back inlets. Shortly, from front dasboard inlets I feel warm air, but from rear roof inlets I feel that normal ( not heated) air comes even if I set a temp control of the rear air conditioner to the maximum. Is it normal? Does it mean that REAR air conditioner is designed only for cooling ? I have 2004 model Lexus LX-470 bought in UAE.
