Navigation DVD Ver. 9.1

I was under the impression that the Toyota Nav DVDs were un-copyable due to the differences between a real 'pressed' DVD and a 'burned' DVD. One has 'Parallel track path' while the other has 'oposite track path'. AFAIK, it is totally impossible to burn PTP since the laser follows a tracking path in the disk and all burnable DL disks are OTP to minimize the layer change for video.
Could you please confirm that you are really using a burned 'safety backup copy of a disk you legally own' and that it works in your car?
I made a lot of coasters trying to prove this bit of information wrong and was totally unsuccessful in having the system read my map data. The disk looked good on the computer and even verified, but in the car, the maps were unreadable (but it did update the firmware).
Inquiring minds want to know.
BTW, my V that I picked up last Friday has 9.1.

I have burned readable DVD's for my IV's nav system with no problem. I was hoping to make one that would unlock the input while moving, which I have not yet succeeded in doing, but I could burn readable disks without much problem. Btw, it was mentioned that the v9.1 firmware might give an option to turn off the nav lockout while moving... any truth to that rumor?

 

Navteq DVDs are about that size, but they also include a national yellow-pages phone directory & nav system software.

 

Got the pics for the 9.1 DVD from my Prius



Don't know if there's any software update to enable the lockout ... of course I have no idea where to look for such hack either

... BTW, sorry for the rotated pic.

 

That's interesting. Could you PM or post the technique and software you used to backup your disk? Perhaps the 2010s don't do the disk check that my 07 touring did as a method of copy protection. Could be that the head unit is incapable of reading that bit of information and only does sector reads, not position reads. I'll try to make a backup of my 9.1 disk and report back on my results.
As far as a lockout override. Would be nice, but I doubt it would be easily hacked, what with all the concerns of the Toyota legal staff. But if there's a secret unmarked button sequence somewhere, I have no doubt that the people here will discover it first.

 

Well that maybe true for newer Garmins ... but on my older Street Pilot? They wanted HUNDREDS to upgrade even past it's original data, which was HORRIBLY out dated and error laden from the very get go.

.

 

I didn't have much in the way of special technique for burning the disk. I just used a RiData dual layer +R disk and Nero 9 on the default settings to burn an ISO at 2.4x speed. So if I were making a copy, I would have just created a disk ISO first and then followed the same procedure. I successfully fed in map data from another version of a Toyota disk as well as from an Eclipse upgrade disk.

The lockout question I had was not so much about a hack - I know that probably won't work as before. But I had the impression from somewhere that fixing the lockout had become a setup option in version 9.1 firmware... like you could actually just turn off the lockout somehow... was that just a bad rumor or is it hidden in the setup menu somewhere?

 

I have a street pilot 2720 update were $69 each or $119 for life, 4 update a year. I went the life upgrades years ago. Now the upgrade say nuvi but they work fine with the Street pilot.

 

I'd look in the Setup menus for the Nav system running 9.1. Also, you could do some Web research on the Lexus version of the 9.1 update that supposedly can defeat the vehicle-motion lockout.

There must be some Toyota documentation on what this update contains, perhaps on TIS. Can someone with a TIS account look for this documentation?

 

I couldn't find anything about it in TIS. Maybe I'm not looking right, but I found no mention of it.

 

For those of you guys interested in how I did it. I have Mac using Toast 8.0(at least that is what I remember using since the Mac's internal Disk Utility is a pain to use). Used a DL+R. I burned at normal speed(2-2.4). I did get an error at the very end of the process. I was expecting a coaster. I put the copy in an booted right up. I mainly using Texas as that is where I live. Could it be that there may be some unusable parts of the disk? Perhaps - but I haven't found it yet.

Tonight's trivia - I know where the Nav DVD data comes from: Navteq!

Thank you for contacting NAVTEQ. Currently Toyota does utilize our map databases however we do not produce nor distribute discs for their systems at this time. For information please contact Toyota directly at Toyota Cars, Trucks, SUVs & Accessories or 800.468.6968.

I just made a successful backup of my 8.1 NavDVD onto a DVD+R DL (Dual Layer) writable disc.

On an Acer PC laptop with Vista OS, using the supplied "NTI CD&DVD-Maker" program (v 7.7.0.xxxx), I first read the original to make an "iso" file, then used that "disc image" to write to the blank disc.

I used Memorex 8x DVD+R (DL) from Office Depot, currently $40 for 50 blank discs.

If you have a 9.1 DVD and would like help making a "use-backup" for your own use, you may PM me and I will try to help you.

 

Is the Toyota 9.1 NavDVD exactly the same as the Lexus 9.1 NavDVD?
What exactly is the information on the DVD label on each, please?

 

Has anybody with the 9.1 NavDVD discovered ANY differences from the 8.1 DVD?

First, check Info, Map, Coverage.
The California, Nevada, Arizona region is only about half "covered" in the 8.1 DVD.

Second, can the 9.1 be used while in motion?

Third, and new options or settings.

 

If I can find somebody (with the 9.1 DVD) who is willing to take some time to do the comparison and will sit in their Prius with the 9.1 DVD, then I can sit in my Prius with the 8.1 DVD and we can try to do a detailed comparison.

Even better, somebody locally (Orange County, California) so we can park next to each other and do the step-by-step comparison. PM me if you would like to help.

 

Thank you for the picture. Is it the latest DVD for Nav? When did you get your Prius? I am getting mine next week. Should I get the same version of the DVD?

 

For those who want to know.
It IS possible to copy the 2010 9.1 NAV DVD. I used imgburn on a Vista box using a LG writer and Verbatim DL disk. After inserting the copy, the screen displayed 'Checking Disk', then showed my location on the map. This enables me to keep my original in a safe place away from those nasty valets. Or whatever.
Although the original disk is PTP and the copy OTP, the player either cannot or does not check this parameter, unlike the Gen II under seat player.
And there you have it.

 

First of all I wanted to be post #100 and now I am(I think) - I called my local service/parts dept. They did not have in stock but willing to order at or around 300 bucks. I will pay for it but I would rather find a better price. Anyone order/receive yet? If so - how much did you pay?
