Susiek,Try this.
Startyour computer's music player (not iTunes; for now. we'll do that later).
Put in your usb stick. The player should recognise the presence of the stick.
Instead of playing your music on your computer, you can drag the music items into the usb folder, or section. Mine is on the right hand side of the windows mediaplayer, under sync.
Once you have dragged a tune or two onto the stick (no more we are just trying it out), "eject" the stick using the windows (if that is the system you are using) file explorer. To do that right click on the usb stick icon.
Once the usb stick has been "ejected" pull if from the computer, and take it to the car.
Turn on the medianav system. no need to start the car, just press the on button on the top left.
Once the medianav system has started, push in the usb stick.
Touchthe media icon. It is likely that the mediaplayer will find the usb stick automatically. If not select it from the box on the top left of the screen. Choose usb. Other options in this box will be Bluetooth and iPod. These will be "greyed out".
Select the tune to play.
Press play.
