Just an update for ya. Replacement DVDs for the NAV is a 5 Star PITA!. I have an 04 version and they STILL have not published one. Here's the latest from my new dealer who checked with Mazda NA a week or so ago. THe company who was doing them for my car at least went out of business (NAVTEC-A large supplier in the day.) Mazda is in the process of qualifying a new source and the date has been pushed out to spring of 2010 (is was Summer 2007 last time I heard. The different years of NAV systems sometimes use different mfgs for the system and the DVD. Its just not a plug and play type deal. Also keep in mind they don't always copy correctly. I've read many posts where folks have tried and have had no luck reading the copied DVD. Its really a tough deal. You'll probably just have to bite the bullet and buy the factory DVD IF they ever publish one. This whole mess has really turned me off factory Nav systems for good. Aftermarket is much better supported. Good luck. If they ever publish one, I'll be the first in line so I'll post any results.
