the original DVD X-Copy would work, but it's unlikely you have it b/c they went under several years ago, but it defeats the 360 protection.

 

When I purchased my 06 I just assumed the dvd in the nav was legit and didnt find out till after I downloaded and burned 7.3 that the one already in my car was a copy as well. Copies work fine in my unit.

 

I think the 2006-2008 versions are different than the ones found in the 2003-2005 350z's

 

Something else to consider… older disks can be copied with older replication software, but newer replication applications may have problems with older disks. That’s simply because the CP inside the disk is older, and newer replication programs don’t always handle older “Bozo” algorithms.

Something I always do is using a “drop-dead” date. I must do this since my software is for the healthcare industry and must respect HIIPA mandates. In my case releasing old software exposes my company to significant fines when it doesn’t match current Federal healthcare requirements. So it isn’t about CP, but mostly to meet industry standards (keeping my clients current).

This same concept is applicable to maps from NAVTEQ and Tele Atlas, blending with application software from many companies (e.g., Garmin, Magellan, etc.) licensing the data. The companies providing data need to protect their product as well as insuring it runs under the most current application software. You should expect legitimate “drop dead” dates on the replication side for these products.

If you use a replication application to copy a Navigation DVD, and it fails, then try this:

Quit all allocations, and reset your computer’s clock to 12 months or more previous to the current date. Then run the replication software to copy a commercial DVD.


That may not work, but it’s certainly worth trying if you are unable to copy a DVD.

I'll try to make a copy with my slysoft anydvd, maybe thats the ticket?

 

Updates? Anyone make a working copy? I need on asap, Thanks!

 

^^ Here is what I think is going on when trying to duplicate navigation disks and use the duplicated disk with a different GPS device:

The device’s ROM chip holds a binary string that must correspond with a string in the disk’s header file. If the two do not matchup, the duplicated disk won’t work. The manufacturer’s reason for incorporating this feature goes beyond copy-protection, and extends to insuring that new disks work with older devices, and the reverse (preventing the user from running incompatible components). The string probably contains a serial number and a date/time stamp. It’s likely the same values are imbedded somewhere else in the header record, but in an encrypted format.

And, that is why you cannot simply duplicate a navigation disk and expect it to work.

^^^ I hope you are wrong, why would the OP's orginal disc work in his car if that were true, I doubt it is THAT complicated, seems like a problem with copyrights. Hope someone can get this working, I would love to be able to actually use my navigation!

 

^^ You are correct. It’s not complicated, but instead “protective.” In fact, it’s meant less as copy-protection and more as consumer-protection. The best scenario for a device and its companion software is an arrangement that insures they work flawlessly together. You do this by installing “keys” in both components (the device and its software) insuring that only compatible pieces operate together. Since the “keys” are not designed primarily as copy-protection, you can expect random success (and, that is what we see from some reports).

Notice how there is from time-to-time someone who posts here offering an inexpensive duplicated disk. There are a couple of positive reports from “buyers,” and then it “goes cold.”

I really do believe that some of the people offering duplicated disks believe they will work. Of course, they are naïve, as well as are the buyers of these disks.

You guys are overthinking this.

There isn't any fancy copy protection on these disks. The DVD drives for the nav unit are picky. The disk I finally got to work is a memorex DVD+R DL.

Please do not PM me about copying nav disks, I won't do it. The only reason I copied mine is to try and tinker with it (want to make that stupid nag screen go away, no luck so far).

 

^^The DVD disk has a string in its header record that must match the ROM in the navigation device. It’s not so much copy-protection as insuring the device and the disk are compatible and work together.

Your experience was positive, but that’s because you had compatible pieces.

Yes, the software version needs to match the map disk version. When you buy a new version you get the map disk (DVD-DL) and the program disk (CD-ROM).

Both are easily burnable if you can find disks the drive likes (CD disks are easy, it is picky with the DVD-DLs).

 

I managed to back up my original copy version 6.7 and it works perfectly.
Let me know if you need help.

 

Must be Vacation time for everyone and people need an updated disk because 6 out of 10 replys to posts today are for Nav disks. Good thing most Navigation is built in on the new units of quality and can update online.

 

^^ Good point!

I was thinking the same thing. The better (new generation) GPS devices support downloading your map database updates from the manufacturer’s website, and installing the update using a USB flash drive or SD card.

DVD updates are awful since they are expen$ive and depend upon slow shipping.

This is a good argument for going with a remote GPS black box since this unit often costs less than a DVD update (and updating costs much less and is instant).
