#180 of 209 Navigation system computer 2002
Sep 14, 2011 (4:32 am)
We have a 2002 Toyota Land Cruiser which has served us reasonably well. We actually bought the car for its navigation system among other things, which was system unusual back then. Now the thing has failed and we are told it is the computer itself that has failed. The dealer wants $6K to install a new computer. Of course we choked. They said we could obtain a used one for $2K. I would wonder about their motives. Of course we are out of warranty with 150,000 miles on the vehicle. Can these computers be repaired or are there one available for somewhat less than the value of my car?

From 2006 on or so, you could calibrate our nav and it would hold for a couple of days. Then it would drift off having you 100's of miles from where you actually were.
I tried a nav disk out of our 2005 4Runner which was compatible but that did not help. I broke down for one of my wife's Christmas presents last year (romantic, no?)a nd bought the "disk player" (under the passenger seat part) from an ebay seller (toyolexnavspec). Installed it(easy)and it solved my problems.
The seller was negotiable (about 20% off) and guaranteed my money back if it did not fix my problems. Good luck with yours.

If you go through this thread you will find that someone in the past named a service that repairs these things. I think it was somewhere in New Jersey, but not sure. Of course it would be helpful to get info from someone who had the repair done by them to ensure they have a track record.
I am curious about what happened. Did it simply not come on one day? Had you changed your car's battery around the time of the problem? And do the other functions of the video interface--like the audio and hvac controls and trip info--work?
Good luck in getting it fixed.

Our oldest and responsible daughter borrowed the car, so the details are sketchy, but she said that it just failed to open one day after driving on a somewhat bumpy gravel road. Now it just reads, "No disc found." There is a disc, even a current one, but after having it checked out at the dealer, they came to the conclusion that the computer had failed, charged us $117 and said we could purchase a new one for $6K or a used one for $1200 to 2500 or so. I find rebuilt ones on the Internet for 2004 Land Cruisers, but none for one as old as 2002.

Interesting. It would be reassuring to know that they disconnected and reconnected the wiring harness for the disc reading unit under the front passenger seat and removed, inspected and carefully replaced the disc.
But back to my original question: do the other functions that the computer controls and displays on the screen like audio, hvac and trip info work? (I am assuming that you have roughly the same interface as a 2005, where there are many more functions to that screen besides the nav display).
If so, I would start by finding a replacement for the disc reading unit under the seat and see what that yields. I imagine that could be purchased used for much less than the computer.

Your assumptions are correct in that everything else works, DVD, climate control, audio, just the disc reader seems to be out of whack. Do you know if the so-called computer and disc reading unit for the navigation system under the front passenger seat are separate units? The dealer seemed to indicate that they were one and the same. Interesting that only the navigation system has failed. I reads that no disc is detected. Ejecting and replacing my disc did nothing. They checked it and said the computer had failed and said that they had never seen that happen on any of their cars in their experience. Good to be a first.

I have a 2002 LC had the same problem no dics found. I to went to the dealer 5k for a new one. I took my unit out and shipped it to these guys that I saw here in a thread. I looking for my invoice but the cost to look at it was 149.00 I think parts and labor was no more than 300.00 It was around 250.00. Going on 2 years no problem works like new.

I don't know for certain that the computer serving all those audio, video and other functions does not exist in that unit that contains the disc under the seat, but I would be very surprised if it did. I imagine it would take some time and persistence, but it would be worth trying to find some knowledgeable person at some level in Toyota (bound to be hard to do that by just calling in...but probably possible), or at some other Toyota dealer's parts or service departments to get an idea of where the failed function resides. Parts guys can be a great resource because they have access to service manuals also and they are usually not busy.
I would also give those guys in Mass. mentioned in the thread above a call to see how knowledgeable and familiar they sound with the system. Pick their brains.
This type of failure has happened to others in association with changing the battery of the car. Also, you may try on some other dedicated LC forum like iH8mud for others advice in resolving this.
Good luck and PLEASE post back when you get this resolved as to what you did. If I see anything else on this I will post here.
#188 of 209 Screwed up Navagation system
Oct 07, 2011 (2:52 pm)
I was playing around with my Nav system going into the mode to get the over ride. I noticed on one of the menus that there were a list of maps so I clicked on the first one which is Japanese. Now it says insert new disk, obviously I don't have one. What I can't do is get back to the original system. Now I can't get the menu button is dead, only have partial use of my blue tooth, and can't get back to the screen with the volume icon to get back where I screwed up. I've learned my lesson don't play with toys I have limited know ledge about.
#189 of 209 New Navigation Disc Offer
Oct 11, 2011 (3:45 pm)
I just received in the mail today an offer from Toyota to buy the Autumn 2011 Navigation Disc release (version 11.1) for a "New Lower Price of $169".
I have an '05 LC with the original disc.
Having never updated the disc, I was curious to know if anyone who has done it in the past has encountered any glitches or wishes they hadn't.
It may seem like an odd question, but if you are familiar with some of the posts on this part of the forum related to the Nav system crashing and how big of a problem it is to recover from, I would hate to do anything that has even the most remote chance of causing a big problem.
