Navigation Unit Replaced Twice in Three Weeks!!! - Your Thoughts???
Nav unit was replaced under warranty twice in 3 weeks in my 08 C6Z.
Been using a bootleggged disc I downloaded and burned off the internet for about a year and a half. I think it's V5.0.
Three weeks ago unit gave a message that the disc in DVD is not a map disc. Replaced with a new OEM disc and unit wouldn't read it either or any other disc the dealer tried. Kept giving the not a map DVD regardless of the disc they tried.
Put a new unit in and it worked fine and read my bootleg disc for 3 weeks only to then give the same message and again wouldn't read ANY disc.
Dealer replaced again and this time stated the disc I burned was the problem. I think they're making it up. Isn't the unit just an optical reader? How could a disc that has worked fine for 1.5 years cause this problem!?!?

Being in the computer business and dealing with CD, DVD and blue ray readers and writers... I definately believe your disc is the issue. What I think is that you either have enough scratches on your disc to make it just borderline or that when you burned your image to that CD, the laser on your writer could have been weak and your burn quality suffered. A weak burn or a scratched disk can cause intermittant playback issues. We have seen this many times building servers. First thing I would do would be to clean the disk really well using a soft cotton cloth and some warm soapy water or plastic cleaner if you have it. That or just burn a new image to a new disc. Use name brand media and a different writer if need be.
** Edit..
I missed the part about the original disks not being read either. If its really killing your nav and factory disks cant be read either, that is really weird. I cant imaging that the boot legs software could kill a head unit. Do updated the nav disks do any kind of software update to the head unit? If so, that could render the head unit incompatible with older disks.

I can't see where the disc would be the issue, The lazer never touches the disc, It will read it or it will not read it. I can see the unit not reading the disc, But to mess up the unit so it won't read any disc's I don't see it.
Just my 2 cents.

You actually admitted to the dealer that you were using a bootleg DVD 
If they'll give you another new one, try only using the original DVD for a while. If the problem is somehow coming from elsewhere in the car (unlikely, but possible) then the new unit should die even with the oem dvd. If it works for 6 months, then you switch back to the bootleg maps and it dies in weeks, dvd is the problem.
That being said, the only way I can see the new DVD causing the problem is if it somehow updates the firmware on the nav unit. If all the DVD has on it is map data, then it can't be the issue.
