Hi i have a how to erase everything on your RCA M20 Series V2.18 and i have put songs on it before in the past, but after a while know its telling me that it is full and won't allow me to add any

download a program called "media monkey" this will automatically load your player with songs to the most efficient use of space. It's a free version that you can upgrade. Just google it.

Goto the RCA website and download the latest firmware for it. Install it and it should work fine. You can also try plugging it into the usb and hold the power button for 15 seconds.

i have rca m202a i dont no how to down load the song in .can you tale me stap by stap and how to delit if i dont wont

if you have windows media player try formatting it...that will automatically delete everything so you start all over. hope that works. =)

Ok
the easiest way is:

Open My Computer and go to your sansa folder named something like this "SansaE250"
Open it and go into music and delete all the songs
simply, press CTRL+ A - selecting everything, then press Delete.

to fix it go to the command prompt and format the drive C:\format G:

this does erase everything on your lyra though hope you have your songs backed up...

1. Plug your player in using usb cable.
2. Wait and a menu will pop up with several options scroll down to the option "manage with rhapsody" & click to select
3. Create a rhapsody account and note to the left of the screen rhapsody will detect your player
4. Click on your player screen says"RCA ...." your songs will be listed once you click on the words RCA
5. Highlight and delete
6. To avoid this in the future only use media player or rhapsody not both to sync songs to player

Remember when you format memory like a hard drive you erase everything. Move music to your internal mp3 memory and do a profile - folders should appear. If you have flashed your player with the firmware update you can get 520 songs on the player for both internal and external combined but be warned that if you exceed this count your player will start to forget the earlier loaded songs - listed but not addressable (playable). The same is for the folder count eg. add album = artist + ablum title (min 2 folders). Plus always profile your songs after loading new music or deleting as this is an index build process to play song 152 = title x. This includes accidental radio recordings to MP3s. RD2312 , RD2315, RD2317 Lyra™ mp3 flash player Firmware/Application Upgrade Version 3.11 fixes:

• Supports a total of 520 songs, in up to 50 folders, with up to 8 levels of subfolders.

This player can only handle songs that are in a specific bit rate - lower it to the rate suggested in your product specs. Go to RCA's website if you have lost the documentation. Corrupt file systems can usually be solved with a firmware upgrade (also at RCA's website), but if that fails:
There are two ways to format an Mp3 player - one on the computer itself, and one in Windows Media Player. Both methods will end up erasing all the songs on the player, but the player will be "good as new" after that. Sometimes reformatting in this manner will override the player's native formatting and cause problems - this can be reversed in most cases by updating the player's firmware. Firmware upgrades are available from most manufacturers' websites.

WARNING: The following procedures will erase all songs on the player.

Check if the file system is NTFS. If yes, format it to FAT or FAT32. - Connect player to computer, double-click my computer, right click on icon of mp3 player and select format. This only applies to Windows-based computers.
You can also format the player in Windows Media Player itself:
Connect your Mp3 player to the computer and open Windows Media Player. Click on the Sync tab. Pull down the drop down menu underneath the Sync tab by moving your cursor over the Sync tab and left clicking on the little black arrow underneath the Sync tab. Highlight "name of Mp3 player here 1GB" (wording may vary slightly), and then select "Format." - this should erase everything.
