In discussion with an authority on the Nav DVDs for Cadillac, I discussed cutting copy DVDs from an ISO image and mentioned that the copy seems slower.
I was informed that copied DVDs use a different technology that requires the reading laser to run at increased power with the effect that it can be worn out rather sooner. This applies to any DVD in the slot (e.g. a film), not just a navigation DVD.
As others have noted that copied DVDs sometimes don't work at all, or work erratically, this might be the root cause?
It would also suggest to me that if the laser has a limited life (in hours and not just age), then maybe taking the DVD out when I don't need it for navigation might be a good idea?
