    Hi everyone - first time poster.

    Have just semi-successfully upgraded my 2010 Prado (came with a V16 2009 disc) to V20 using a DVD-R by removing the LOADING.KWI file. DVD Loaded fine in the nav unit under the seat and works fine however I can't search for any addresses in WA. In comes up with all the Aussie States (except WA) as well as NZ's South island. Weird - however the WA nav map is working fine - I just can't set any WA destinations including my home - old DVD worked fine here. Any thoughts.

    I might source a DL DVD+R and leave the ISO untouched and try that. I may pull the disconnect battery and try that too.


    Cheers

    G'day crabcooker, welcome to GPS Power.

    I'm guessing you may have a burn problem with that SL disc missing WA and Nth Isl NZ destinations. You could try to re-burn it to SL using another brand disc/different burner/slower speed. Also it seems [Only registered and activated users can see links. ] got a DVD+R SL to work in his Toyota Kluger Grande 2005. That's the first report here of the SL +R working, only -R and +RW for SL and +R DL known to work prior.

    Further reporting on your experiments regarding working disc types either SL+ &/or DL- will be welcomed mate.

    The DVD works perfectly for my Toyota Kluger Grande 2005, I also had a workaround for the LOADING.KWI file. These are what I have done from the information gathered in this thread:
    1. Download the "Whereis v20 Toyota Australia - NZ 2014" iso file from the shared torrent. This file can not be burned to a normal 4.7GB DVD as it is too large and people have suggested to remove the file LOADING.KWI, it is OK but we can do a little bit more than that.
    2. Use PowerISO to open the iso file (Original) and remove the LOADING.KWI and save it as new iso file 1. (PowerISO was shared by someone in this thread, thanks for that!).
    3. Use ImgBurn to write that new iso file 1 to a DVD+R 4.7GB at x4 rate (called DVD 1 without LOADING). (Free at [Only registered and activated users can see links. ])
    4. Again, use PowerISO to open the iso file (Original) and remove the file POISR001.IDX (in the IDX forder, I guess it stores points of interest) and save it as new iso file 2.
    5. Use ImgBurn to write that new iso file 2 to another DVD+R 4.7GB at x4 rate (called DVD 2 without POI).
    6. Put the "DVD 2 without POI" in the car first, it loads contains in (as the LOADING.KWI is in there) and works perfectly. However some POIs might be missing.
    7. Replace DVD 2 by "DVD 1 without LOADING", as the loading has been done before, this DVD just works seamlessly without missing anything!!

    Cheers
    Hi all,

    Owner of a 2010 Lexus IS250 here. I completed the upgrade process as per the above steps using a DVD+RW and everything works as expected.

    Initially I had a upgraded my maps to V20/9 using a SL DVD+R disc by removing the LOADING.KWI file. The upgrade process worked I suppose, but the "loading" screen with the progress bar never appeared at all during the process (I guess due to the missing loading.kwi file). The upgraded maps work, but it's extremely sluggish when searching for Street Names and Cities. Just today, the Navi unit crapped itself and complained there was no DVD inserted

    I was not content on restoring my OEM v16 disc with 2009 map data, so I tried the 2-disc / 2-step upgrade process, as described above. This worked a charm and there is no more sluggishness / lag when searching for Street Names and Cities. This time round, there as a LOADING screen and progress bar during the updating process.

    Thought I share my experiences here. DVD+R works, but I would not recommend it. Go for either a DVD+RW or DVD-R if you can to save yourself time and headache.

    Cheers

    My best guess on that is;
    1) The unit was compromised by not having some incremental update and/or bug-fixes issued on a map disc since V16, all of which would have been contained in the complete OEM V20; or
    2) DVD+R SL are not fully compatible with some of these Denso units.

    Thanks for the report, much appreciated.

    Thanks for the tips everyone - much appreciated. This time I have had success but not without a major drama first. My vehicle is a 2010 Prado Kakadu which comes with factory Nav. My original Nav disc is V16 and looks to be an original disc too as expected. The disc is dated 2009 which makes sense.

    I thought I'd share what I found today:

    I ended up buying some DVD+R DL discs to try and burned the complete ISO using Imgburn as described in this thread. I had to manually adjust the layer break as also described here. I used the value - 1261456 as suggested.

    Previously I has burned the modified ISO (loading.kwi removed) to a SL DVD-R. This was semi-working as I described in an earlier post except WA (and NZ South) was missing in the search area yet the map was working fine. It appears the modified disc was no good as I disconnected the battery today for the other upgrades and when I connected the battery backup the DVD Nav system failed when I put the car ignition on - my main centre console display came up with a 'Consult Dealer' error. No Nav, Radio, Cameras, Trip computer etc etc. No button response at all. At this stage I was crapping myself.

    My mission was to then replace my DVD-R disc with the original V16 disc but I had no way to remove the suspect disc from the drive. I plugged in my laptop to the OBD connector under the steering wheel and ran the Toyota Techstream software. I could not even connect to Nav ECU (though everything else was OK). I was hoping I could force the system to eject the disc. Connecting to the Nav ECU would normally enable a special diagnostics mode on the main dash display which currently has the black screen and the 'Consult Dealer" - no cigar. I tried many things but no go - my main display was offline.

    I resorted to removing the DVD-ROM drive from under the passenger seat. No too bad here. I didn't have to remove the seat as my service manual suggected. The scary part was that I then had to dis-assemble the entire DVD unit to remove the old disc and put the original in its place. This took a lot of patience as the disc is locked into the unit and being slot load drive there is no tray to force it ut with a paperclip. You'll need some jeweler's screwdrivers here. Pretty finicky task but if you are bit of an electronics or computer hardware tinkerer it should not be a problem. Any way I successfully replaced the disc with the original and fired it up. The main display came back to life.

    I then took the chance and put in the new and complete DVD+R DL disc. It loaded up fine and this time there was a loading progress bar - the modified single layer DVD-R disc didn't have this. Success - in my search area and can now choose all the Aussie states as well as both main NZ islands.

    Does any one know of an easier way to force the DVD-ROM drive to eject the disc without resorting to taking the drive apart? This was the major drama as the bare DVD PCB and optics are very prone to dust and/or damage.

    I haven't disconnected the battery again though. I'm not yet convinced the new DL V20 disc will load up properly next time like the original V16. I'll get the courage soon enough. Hope that helps.

    Thanks for everyone's help. This thread is awesome.

    Whew! Bet you were seriously cr@pping yourself mate. Here's what could have happened, and if i'm right it's a warning for others who use the modded SL map disc. I know that the unit software [firmware] is stored in volatile memory on these Denso/DVO Dayton units, this means that if the unit is powered down for an extended period the volatile memory is lost and hence with it, the firmware. Anecdotal evidence is that it will not be wiped if that's only for a relatively short period so there's maybe a 'keep-alive' function, a charged capacitor or something as i mentioned in Post #80. Normally it's not been a problem with map data discs which it seems are ejected on re-powering and an OEM disc can then be inserted to rewrite the software back to the unit. I'm suspecting because this particular V20/V9 is an OEM disc that then maybe such a disc has some 'marker' on it telling the unit it's OEM [i'm now quite sure it is OEM going by the fact it loaded firmware for your unit]. So the unit looks for the firmware to write to v.m. and when it's not there it locks itself and asks for dealer intervention, very unsettling that.

    I don't know if it will work for these units, but i've heard of car infotainment/gps units which would refuse to eject a disc being coaxed into doing so by powering them down for a period and then holding the eject button before powering on again while continuing to hold it in. Not suggesting anyone try that as an experiment with one of the 'SL sans LOADING.KWI discs', but worth keeping in mind to try before opening a unit up. Never had to do it myself though.

    As i also mentioned in Post #80, i had a B4 which would have needed a dealer code loaded to the computer if it was left w/o a power source for too long. Fortunately i didn't get caught because i'd heard about it beforehand so i've always used jump leads connecting the vehicle terminals to a slave battery for any complete power-downs, saves reprogramming the radio anyway at the very least. My rider mower battery is fine for that short and minimum load.

    Thanks for that Neil. Yeah I had the main battery off for about an hour today and the Nav spat the dummy straight away after ignition on - screen was blank for about 10-15 seconds before the error message appeared. This was the first time I had disconnected the battery since I put the modified ISO DVD-R SL in a couple of days ago. Glad it happened now and not some other time when the battery goes completely flat or something. My guess is the modified ISO is the cause of my issue as you would potentially not notice the issue until the battery is disconnected for an extended period. This could be months if not years depending on the car and user. People like me with 4WDs are constantly tinkering with the electrical system, including the (dual) batteries, but those with regular cars may never see the a total 'firmware' loss under normal use including a quick battery change every few years.

    Next weekend, and after a couple of cans of courage, I'll disconnect the battery again for another hour or so. This will test the unmodified V20 ISO on the DL disc currently inside the DVD unit to tell if it has all the necessary files to boot the system from a fresh start. Worse case scenario is that I have to remove the unit and replace the V20 disc with the old V16 (with all the good files) and go the two step upgrade path again V16->V20. This process would take a good half hour start to finish. Dis-assembly and re-assembly of the DVD-ROM unit is the most frustrating part being delicate type work. I'm semi-confident at this stage that the system will boot

    Cheers for your help. I have learned quite a lot over the last few days.

    The 'Consult Dealer' (or similar wording to that effect) also happened to me as well on my Lexus IS250 (when I was using a DVD+R with the loading.kwi file removed to fit on a SL disc).

    I had loosened the connection on the negative terminal on the battery for over an hour (due to installing HID headlights) and when I re-connected everything back up, I was met with a blue navigation screen asking me to take the vehicle back to the dealer. I'm a complete novice at tinkering cars and electronics, and I literally crapped myself!

    Luckily, I googled the error and it was simply a sequence of touches on the nav screen to force eject the map DVD from the DVD slot behind the fascia (i.e. touching top RHS corner of the screen, followed by the bottom RHS corner). I re-installed the original OEM disc that came with the vehicle and everything started working again (navigation, rear camera, etc).

    I'm hoping the 2-step/2-disc update process I followed this time should alleviate any need to revert to the OEM disc should the battery be disconnected again...


    Edit: Anyone know when the next WhereIS map update is due?

    I can confirm that the V20/9 DVD is in fact not an OEM DVD, as I had to reinsert my original disc after my car's battery when flat...
    Wrong, see post #91 by gshyoung confirming it was in fact the OEM disk with LOADING.KWI removed.

    Great info there gshyoung. Thanks for that. Will certainly try your touch screen trick next time Sounds like I may need to try it sooner than later.
