I can't find out how to open this thing!

The T20 has a 'built in' battery like most modern mobile phones have. Changing the battery isn't easy, it involves taking the player apart to access the battery. It may be easier to replace the whole MP3 for a new one.

If you own the data cable for the device you may not need the software. All mp3 players may act as file sharing devices. The software included with these devices is usually more for convenience and not really needed. Plug your data cable in to your computer and wait for it to recognize your device. Open My Computer and near the C:\ drive you'll see a new disk appear. Most likely it will be named E:\ or F:\ . Double click to open it. This will tell you if there is any files left on the device. I'm not familiar with that brand, make or model but this is pretty much industry standard. If for some reason the device moved your mp3 files outside of the typical music folder simply drag them back in. :) Then it will be able to read the files correctly again. :)

Good luck!

Item has probably been in a shipping container for quite a while and the battery could be defunct.

I suggest you read the instructions and if you are certain they were followed closely and the Mp3 player doesn't work as advertised you should return it.

File System Error is nearly impossible to fix - update the firmware and pray

push the tab in on back of unit and slide battery off install new battery by sliding it back on and you will hear it click back into place

I have the same problem with my player. The manual says the following under the specs: Power Power Supply AC Adapter DC 5.0V, 2A Battery Lithium Polymer Battery Does this help? chichuck

sorry dude. but i found out that u can change the battery. its a lithium-ion battery. and the sucky thing is that i is non removable.
sorry!

Are u retarder or maybe u can´t read?? he wrote that he can´t any options in the player

Check the battery to see if it has the original capacity if not you may need to rejuvenate it. Also try to open the unit and reattach the LCD. Good Luck.

You can try getting the firmware/drivers here - http://www.auviusa.com/downloads.php Installing those over everything might solve it, but most chances that it won't. You probably won't find anyone that would fix it for you(techs don't like wasting time working on these little things), so think if you wan't to risk loosing the functionality you have now before opening it up.
