I was looking at page 9 of the owner's manual and noticed that your license from TeleAtlas allows you to make one copy of the data. Maybe we can get Pioneer to give us exact instructions on how to make a copy of the hard drive that will not crash during use. That is the problem that you guys are experiencing right? I doubt they will be willing to help but if the license in the Z1's manual says you are allowed to, they should provide instuctions on how to do so. Obviously our Z1's didn't come with Navi DVDs so it's not so easy to make a copy of our data. Just a thought. Any comments?
