DVD Nav 8.1 hack on 2009 prius?

[polishz3]

After much searching it apears that the 2006+ prius, has different loading.kwi gen 5 than the camry gen 5 (5.1). The secret menu in prius is in the display button not the volume button. And no overide feature is available that I can see.

In other words, no software override.

Did anyone find media that works in the Prius DVD drive? I obtained a copy of 8.1 and the burned copy works great in my '07 Camry but I get the read error in our '07 Prius. I believe they are both Gen 5 systems.

It's been a while since I've posted on my own post about this...

I've tried a number of DVD media and 3 different types of burners.. I have always hit an error when my Prius would read the disk..

I'm no longer able to test this While creating a new image from the navi dvd, my DVD drive decided to malfunction, scuffing and putting deep scratches into my navi dvd

I hope other users here on PC don't experience such a futile effort that I did

Good luck!

(I'm using a friend's 7.1 DVD)

Guys, I need your help.. in final, did anyone copied a Prius navigation DVD with success, and did you find how to do this operation?

I've created also a topic at this address: http://priuschat.com/forums/gen-ii-p...ginal-dvd.html

Can you please advise me step by step how to copy this DVD?

I can confirm that under the best situations burning at the slowest rate both memorex and verbatim failed in Prius 2006 and 2007 (gen 5).
Prius 2005 (gen 4) had no problem even with faster speed and regular memorex media.. first try got it.

i verified the dvds 3 times and they work great in computer then I put it in the car dvd drive and got the error and took out and tested it. the DVD is now unreadable.. this is the weirdest thing i have seen.
Any backup DVD i put in the Gen 5 nav prius becomes unreadable.
needless to say that original dvd ver 9.1 and 7.1 works flawless.
I have tried an external LitOn and an internal Samasung drives all with correct book type.

loumarjr you mentioned

did you have success with that setting on gen 5 prius?
first try or some didn't work?
I used verbatim 2.4x dvd+r DL made no difference..
do I need to disconnect the battery maybe?

I'm guessing the new firmware is checking the pressed DVD information to check for an original disc. If its something as simple as a name or number check you should be able to use a hex editor to "fix" the firmware. The only problem is finding what the firmware is looking for and editing it out or changing it to look for a DVD-R. We really need a good hacker look into this and fix it for us.

1)the ONLY difference bet copy and original is the track direction OPT vs PPT. there is no way to match that with current tech for regular users.

2) considering what you say is correct about the dvd checking itself to be original... then why would the same copied dvd work on ALL other gen 5 cars but not prius 2006-2009

3) lets say that the software is set to check only in prius which is very weird thing to do then the copy dvd with loading.kwi from an older model should be the workaround the protection... has anyone tried that?

if that loading.kwi from version 5.1 gen 5 dvd does not solve this then our problem is navigation dvd drive in prius being toooo sensitive just like the 2001-2003 cars. that would really suck and I have absolutly no way for it.

I also dont really get why it works in a Lexus and not the Prius. Same generation NAV just different car. Its even the same disc. I downloaded my copy from the net and people said it worked in the Lexus.

I am having the same problem with the 8.1 disc on a 2007 prius. I used a Memorex DVD+R DL disc and get a read disc error.

It's possible that the media determination algorithm in the servo firmware is sophisticated enough to know you have a copy.

Anyone gotten this to work on Prius 2006 up? If so, what media did you use?
