I got ya ... I myself asked the dealer to order the new DVD under the TSB ... they gave me BS that it was backordered and I said fine ... order it & call me when it comes in ... to this day ... still on backorder according to them!
I think the whole TSB is bull ... My car has never shown up in the wrong place on the map .. and if it does ... all you have to do is recalibrate the GPS ... no need for a new disc.
My thoughts are that Toyota knows that people found access to the Service Menu & I believe that this TSB is their "fix" to prevent them from lawsuits. As far as the data version is concerned ... they are only replacing teh disc that was "defective" ... so they are replacing the v5.1 w/ an "updated" v5.1 ... you honestly didn't expect them to give you the milk for free when they could sell you the cow !!
Like Mattbar1, I am having trouble burning a readable disk. I am using the Nero software that came with my external dual layer DVD drive. I am using Memorex DVD+R DL media. I will go out and buy some Verbatim disks tomorrow, but I am curious if there are any details to burning this that I could have omitted.
After replacing the loading.kwi file the new disk contained 212 files in 7 folders with a total size of 7,8803569,167 bytes. This exactly matches the original DVD adjusting for the difference in the file size of the one file that is different.
One thing I did that I was not certain of was I gave the disk the name: 464210-0790A which was how my original DVD shows up. No one mentioned the disk name, so perhaps this is not important. When I put the DVD in the car, it first says no DVD is inserted and then it says something like. Cannot read the Maps DVD, see your dealer.
I tried the trick of disconnecting the negative supply to force a reload, but it still could not read the disk. I put in the orignal disk and it said loading for a while and then was back to version 6.1.
Anyway, before I try burning different media brands, I was wondering if anyone has suggestions.
I'm in the same boat but I think what you have to do is burn the disk in iso/udf format.
I'm doing this now but it's taking a long time to burn.
I'll post tomorrow if this works or even if it doesnt.
I still am unsure why some disks work and others don't. UDF mode should be used because that is the format of the original disk. Like I said I went through at least ten disks trying different disk names,same name as original disk, different software settings, etc. I could not find a trend.
I did exactly as i was supposed to and it did not work. I used a Memorex DVD+R DL. the nav says unable to read disk. My only questions is, I cahnged the name of 5.1 file, does it have to be Loading.kwi
I am not exactly sure what you mean by your question, but if you are asking can you change the name of ANY of the files on the disk and have it still work. The answer is no.
Copy your 6.1 disk to a folder, and move the loading.kwi file to a different folder and change the name of that file to something like 'originalloading.kwi'. Download the replacement loading.kwi to somewhere on your computer, and then copy this downloaded file to the same folder that you copied your disk, resulting in all the same names of files in that folder as before. The only change is that instead of about 71 megs for the loading.kwi file its now 46megs.
If you havent yet tried to create the 'new' disk with the downloaded file try this:
Get your 6.1 disk and just create a back-up of that disk, using dvd/disk copy. Dont try changing any files or renaming stuff just create a backup disk.
If this works then you know atleast the drive and blank disks you are useing will work in the car.
Once that works, then you can proceed with replacing files, with confidence.
If this does not work, then you can focus on getting a drive, software and blank media that will work.
The verbatim disk worked for me, this does not mean you must use these disks...I am sure many brands will work.
I tried making the DVD using the Verbatim DVD+R DL. My burner does not have a choice of UDF mode it. It has advanced choices of Clear archive bits of written files during ISO refresh. It has a choice of Data disk or bootable data disk. I choice just Data disk. You can get disk information and I see that the original disk says:
Track 01: 0 7,723,072 KB, UDF/ISO 9660 (Mode 1) Whereas my copy says
Track 01: 0 7,697,440 KB, UDF (Mode 1)
I just copied the files from the DVD to my Hard drive, then copied LOADING.KWI to that folder and said it is ok to replace it. Then I selected all the files and burned the new disk.
I was very hopeful that the Verbatim disks would work, but it seems to be something in how the burner is configured that is causing the disks to not work correctly.
Any suggestions? Having seen the prior message that setting the mode to UDF/ISO didn't work makes me think it is more than this anyway.
What about the archive bit, does that matter?
What about the DVD name, what have people who have done this successfully used for the DVD name?
Any suggestions?
eredleaf I feel your pain. I have done the exact same as you, and the nav still says disc is unreadable. I even went out and bought a new DVD burner and still not luck. I have ruined 5 DVD's sa far.
I would love people who have burned readable DVDs to post details of what they did (i.e. configuration settings) and hardware / software and media they used.
I was going to try to Find the LG GSA-E10L external DVD burner that Mattbar successfully used.
My latest failed attempt was using Prassi Ones software, following a procedure I saw on the lexus forum. They said they used this software with Memorex media, so that is what I used for this attempt. I was able to burn a disk with this software that says it is UDF/ISO 9660 format, but it is still not readable in my Sienna.
Using Nero 7 burning rom it will not let me add Alldata.kwi with a UDF/ISO 9660 compilation. It says files over 2 GB are not allowed in ISO, use UDF. I had a previously faiiled attempt using nero express which created a UDF disk, so I did not burn another disk from Nero Burning rom.
I also thought that perhaps the order of the files mattered although that is probably a silly thought, but just in case I did make one disk with LOADING.KWI as the first file in the compilation. This didn't help.
Another thing I was thinking about trying was to edit the alldata file in a hex editor and create a version of this file that just has a little bit of the data. Then all the files would fit on a single layer DVD. I know it wouldn't work for navigation, but I thought the cars Navigation would at least attempt to load the system if it could read the disk (i.e. I would see loading rather than cannot read Map DVD or no disk installed). That would let me test many configurations at about $0.20 a disk instead of $3 a disk. I have not done this yet.
In my posts I say everything that I have done. I didnt change any settings or do anything our of the ordinary. I did use UDF. A disk copy should copy everything exactly like it is on the other disk to the new one...
