Cannot access Music and Voice menus

if you pause the song that is playing the symbol next to the battery should change to a folder. when it does you press the mode button and it will bring up a menu called music mode. if select local folder at the top you can access all your music or delete the current song or delete all the songs

The root folder may be the culprit on this one. My advice is to add tracks like so Artist>>Album>>SONG.mp4 root folders can only accept x files

Download the special firmware of your daughter's device , after that you shouldn't forget to restart it . The special firmware could be found on the manufacturer website .

I started to have the same problem today and was also getting a "Library Error Encountered...." message. I was able to resolve it by Formatting my player. I lost all my data and settings but now I can put music on it again. To format your player go to the Home menu-Settings-Common Settings-Format

I suggest taking a small screwdriver or tip of a pen and holding down the RESET button on the back of the device. This should return the device to it's factory settings. Like getting a brand new MP3 player. Also make sure your memory is not full. You can delete files my opening up My Computer, then GPX device, then Portable Memory, Then Music and then delete songs you no longer wish to hear.

first connect your mp4 to your laptop with a usb cable. once it shows up on the laptop copy or cut and paste your music to the root folder of your mp4 or the music folder. after that is done disconect your mp4 from your laptop.

restart you mp4 and your music should now show up. enjoy your music

hello there you i have got the same problem... play a music then go to the menu and clik on repeat then chose normal instead of intro.. that it and it worked... take care

To delete songs from your device follow the steps below
You have to make sure that the device is on MSC mode...then make sure your device is plug in to the computer..Then go to programs - accesories - windows explorer, find the SanDisk in my computer, go to media, music and delete them from there.
Either under sync panel in your windows media player it will show your music when it's connected. just click the plus signs for what song you need to get rid of, right click and click delete.
To format it..on your device..go under..menu, setting and there should be a format option option there..let me know if that doenst work for you...
Hope this helps

P.S.Please rate accordingly...
Thank You

I came across the same problem with my Muvo V100. It appears that the unit has a folder access limit of some kind (seems to be 24 folders not sure what detrmines the ones it chooses). I synch with Windows media player and it creates a folder called Music in the root. Within that folder it places sub folders named for the band that the music is from. Within those folders it creates yet further sub folders with the name of the CD the music came from and then finally within those it places the MP3 or WMA files. It appears there may be too many sub folders for the Muvo to be able read all the music. I took all of the MP3 and WMA files and pulled them out to the main Music folder. I then deleted all of the sub folders named for the bands and the albums. When I start the Muvo now it allows access to all of the songs. There may be a way within Windows media player to configure the synch so it doesn't create all of these sub folders. I've not checked. If it is then it would eliminate the manual work of pulling the music files out to the main Music sub folder.

ok...here goes...

go to "My Computer"

Right-Click the "Removable Disk" icon, and scroll down to "Properties"

click "Properties" and another window will appear. There are Tabs at the top of the window. click the "Tools" tab.

select the "Check Now" function located next to the "Error-Checking" option. ANOTHER window will appear.

select "Automatically fix file system errors" and click "Start".

This takes around 15 seconds and usually fixes the problem. you will then be able to add/delete files in the MP4 player.
