How do I set up my mp3 player to receive my music files?

Attach a USB cable from a USB port on your computer to the USB input on the bottom of your mp3 player. Make sure that the player is in the Media Transfer Protocol (MTP) mode. This can be done by pressing the M button. This is the button on the center of your player. Open Windows Media Player on your Windows 98 SE, Windows 2000, Windows XP, or Windows Vista machine.

Make sure you are using either version 9, version 10, or version 11 of Windows Media Player. If you have version 9 and have Windows 98SE as your operating system, you will need to visit the Download Center for updated drivers. If you have version 9 and run Windows XP, we recommend upgrading to version 10.

How do I transfer music files into my player?

If you are using Windows Vista with Windows Media Player 11, you will need to follow these instructions.

What is the difference between the USB and MTP mode?

The USB mode uses a file transfer class called the MSC (Mass Storage Class). This was developed as a way for files to be transferred onto an external drive such as a flash drive or an external hard drive. In this mode, your mp3 player will look and function like an external hard drive in that it will appear in My Computer as a separate drive. This transfer class is not very specific to the transfer of media files so the MTP (Media Transfer Protocol) was introduced. The difference with media files, specifically music files, is that they demand much more management.

Downloading services can require special licensing and a limit on the number of playbacks a music file can have. The acquisition, restoration, updating, and backing up of these licenses as well as compatibility issues with file type and compression ratio within these digital music players demanded a more user-friendly and functional approach to file transfers. For this reason, you will need to have Windows Media Player 10 available on your computer to utilize MTP. Those who have Windows Media Player 9 on their Windows 98 SE, Windows Millennium Edition, and Windows 2000 operating system will need to update using our Download Center. We recommend the use of MTP over MSC (the USB mode on your player) because it is more specific to the transfer of music files. To change this setting, press the button on the right side of your player marked USB/MTP.

Why am I not able to listen to my music files?

Check to see that when you rip a music CD that your music is not copy protected. The RIP function in your Windows Media Player will allow you to convert the music CDs you have purchased into either an MP3 or a WMA format.

To adjust the copy protection setting on your ripped music files,
  1. Open the Tools tab at the top of your Windows Media Player.
  2. Select Options and then select the Rip Music tab.
  3. Choose the type of music file as well as the quality with which you would like to save the music. (Your GPX player has the ability to play music files in both the MP3 and WMA format.)
  4. Make sure to use MTP when transferring copy protected WMA files.
Why am I not able to transfer music files into my player?

Check to see that the hold button is not turned to the locked position. If so, switch the hold button to the OFF position. This switch is located on the left-hand side of your player. Also, check to see that the files you are attempting to transfer are in either the MP3 or WMA format.

Why is my player skipping tracks or reading an error?

You may be receiving an error message if you are playing a copy protected music file. This may occur when you are loading a music file into your MP3 player that has either been corrupted or it was incompatible to play on your device. Certain mp3 players can sometimes only play downloaded music from certain downloading services. Part of the agreement with some downloadable music services can be that even the music that you have purchased can only be used by a certain number of computers. Another limitation could be the number of times a music file can be transferred to certain authorized devices.

Check with your music download provider about possibly updating or restoring music licenses for purchased MP3s or WMAs. Another source of error might be come from the version of Windows Media Player you are using. If you are using version 9 or an earlier version, you will not be able to transfer purchased songs or songs that are being sampled as part of a subscription. To remedy this, upgrade to Windows Media Player 10.

Why is the use of Windows Media Player recommended?


We recommend the use of Windows Media Player because it acts as a filter for what your MP3 player will have the licensing rights to play. If you open the window of your MP3 player and open another window that contains your music files, you can transfer music files by dragging the icon that represents a particular music file into the window for your MP3 player. However, this method will only copy these files without differentiating between playable and unplayable music files. Windows Media Player will display a synchronization error if the correct licensing is not in place. Contact your music download provider if there is a conflict between what files should and should not be playable.

What if I cannot troubleshoot an error message?

You will need to format your player. Note: Make sure all of your music files are backed up on your computer or other storage device.

To format your GPX MP3 player,
  1. Connect your player to your computer using your USB cable.
  2. Within the Start menu, select My Computer.
  3. In the My Computer folder, right-click on the icon representing your GPX player.
  4. Click Format from the list of options provided. Warning: Formatting your MP3 player will erase everything you have stored inside your player. (A warning will pop up to make certain that this is the choice that you want to select.)
  5. Once your player is formatted, reload your music files onto your GPX player.
How do I recharge my Lithium-polymer battery and how long will that charge last?

Your Lithium-polymer battery is recharged when connected to your computer.  Turn the player off and connect it to your computer via the USB cord.  The computer must be turned on.  Initial charge should be for 10 hours with subsequent charges 3 to 4 hours for a full charge.  A quick charge of 1-1/2 hours will give you a 70 percent charge.  A fully charged battery will last up to 15 hours under normal use.

What if I am away from a computer and need to recharge my battery?

You can also recharge your battery using an AC adaptor that we offer as an accessory.  Go to the Parts and Accessories tab to order it using your charge card.  Cost is $14.99 plus shipping and handling.
