Hi SonicSam,
Welcome to the board and the community of MP4 player owners

.
A few things.
Firstly, the manual isn't applicable for your player as it's based on the old Nano clone players. This should is a touch screen one.
Secondly, I just bought one as well. It's only a 4GB version though. Going to post a review shortly on it once I get my video camera connecting to my PC again. These are neat little players to play around with. It's no way as good as a real iPod/iPhone but it's pretty good for the price you're paying.
Thirdly, I agree with makd511. $37 for 16GB is very dodgy, so I would keep from placing feedback until you get it and confirm the storage on the player.
Fourth, don't try to upgrade the firmware on your player if it's working fine. You only need to look at the [Dead Players] section to see what I mean.
Lastly, if there's any questions you have, you are more than welcome to ask and post them here.
