I have a Philips GOgear SA5285 and I can load the audible audiobooks and they go to the audiobook file but when I load my library books from Netlibrary.com they load as songs and do not have book marks, so...
If you are a newbie, and you primarily want the mp3 player for audiobooks, then go ahead and take this player back to the store - I'll tell you why:
The deal between Audible and Philips fell through before the latest series of GoGear's was released. Therefore, even though the player has an Audible folder, it will not properly play Audible audiobook files. Sad, but true.
Your post reminds me that I need to write a Consumer Watch article on mp3 players that claim to play audiobooks - 90% of them will not easily allow you to play audiobooks - you will have to jump through hoops.
If you still want to try, here is what you want to do:
1. Delete any audiobooks off the GoGear, but make sure that you have a copy of the audibooks on your computer itself.
2. Open Windows Media Player. Find your audiobook files in your library. If they don't show up, then you will have to move your mouse over the Library tab - a small black arrow should appear underneath the word "Library" - click the black arrow and select "Add to Library". Click "Add" and find the folder in which your Audible files are stored. It may take several minutes, but Windows Media Player will add these files to Windows Media Player.
3. Right-click an Audiobook file starting with Chapter 1 of whatever book, and select "Advanced Tag Editor". One-by-one, manually assign an a track number to each audiobook chapter - Track 1 for Chapter 1, Track 2 for Chpater 2, etc.
4. Now, re-add the audiobook files to your GoGear.
5. You might additionally have to go into the Settings menu of your GoGear, and turn Shuffle mode off - your user's manual can show you how to do this.
Sound like a lot of work? You betcherbottom dollar it's a lot of work. This particular mp3 player is not the best for audiobooks.
