Hi, I've been using Nanos for several years now to listen to audiobooks at the gym and have never had a problem with any of the others bookmarking where I left off. But the G6 always skips back to the first stop I've ever made in a book if it hasn't been used in more than 24 hours. Example: I listen to part of an audiobook on Monday, then when I go back to the gym on Wednesday, it's gone back to the point where I first stopped listening to the book ever (say the previous Friday). If it's of any help, when I turn on the Nano in this situation the comes on and the whole thing boots up, unlike if it's been less than 24 hours when it goes straight to the audiobook screen. And, yes, I do have "remember playback position" on. As I said, I've never encountered the problem with any previous generation Nano (I have 1st, 2nd and 4th)they've always just picked up where I've left off no matter how much time had passed. Anyone have the same problem? Explanations? Fixes? Thanks!
