So typically we go where there is no cell reception in certain area's and i wanted to load a bunch of music on a USB device or iPod. I tried a older Ipod which I plugged it into the USB port and it wouldn't read anything screen was just blank. Tried a USB memory card storage device that seemed to read the music and would show the songs and artists on the screen from the drive, but wouldn't play anything. Does the audio have to be in any special format ( All the files were in mp3 format ) ?

Is there any trick to get a USB or Ipod to work ?

Thx
Dave
