I have a D900i phone with an mp3 player in it. I have downloaded music from my computor and put them on the memory card in the phone. When I try to play them via the phone it keeps turning off. How do i get the tunes to play

first insert your card to computer, use card reader your card will show as removable disk
if the card was show, open windows explorer, search music that you wan to download to card
select the music file that you want to insert to card
right at file that you select then click copy
after that go to removable disk drive, open it, open the folder music/sound
at that folder right click and click at paste
and you done the process download from computer to card
eject your card from your computer
insert your card to the phone and you canplay music at your phone

i hope this helpful
thank you for using fixya

this is one of the disadvantages for this mobile ... you can download directly from internet ,, wap ,, from jetjar.com for example.

Could be you have bought a microSDHC. I think these mobile only support microSD. To find if the card is being recognised by the phone, go to the settings menu and look for a "memory" menu. This will tell you how much memory the phone has found, if there is only the 10MB internal then the card is the wrong type.

try putting a folder on the sd card name it Music then put your music on that

yes you can, just put the mp3 file on folder "Sound" on the external memory, it will be automaticly put  in your playlist mp3 player.

Your music may be located in a folder your phone doesnt recognize...that happend to me at first.

First you want to format your memory card through your phone. This will place the required folders on the card.

I used Windows media player to sync the music on my computer to the memory card using a media port on my computer. (just inserting the card directly to my computer). Once music was downloaded I looked at the card through "my computer", and noticed folders...one named "Music" and the other named "My Music". I moved the files from "Music" to My Music". Reinserted the card into my phone and the phone picked them up.

try just sending music from your pc to the memory card

You can use Windows Media Player's "Sync" function to transfer music from your music library to your phone, but you need a data cable to connect the phone to your computer, or you can use a USB memory card reader that allows the computer to see the memory card as if it were another drive. NOTE: The i880 can ONLY play music files in an .mp3 format; if they are in ANY other format, they will not even show up on the song list on the phone.

It is easier to get a SD memory card for it. Drag and drop the music onto the window which represents the SD memory card and then just put the SD memory card into the GPX MP3 player. I have the same MP3 player and it works nice... it was a good deal for the money! Take the savings and invest in a cheap SD memory card and you will be happy.... I was!
:-) Good Luck!
