What music players are compatible with the iTrip Auto Universal Plus?

First, the digital audio player must have a standard 3.5 mm headphone jack. Any iPod, Zune, Sansa, and most other mp3 players will have this headphone jack.

Second, your player must use a USB cable to connect to your computer or charger. You will use this cable to connect the player to the female USB port of the iTrip Auto Universal Plus. Although you do not HAVE to have this connection in order to transmit the audio to your FM radio, you must connect a USB cable if you want to charge your player.

Finally, to use this device with an iPhone, you'd need a Griffin headphone adapter to fit the plug into the iPhone's recessed headphone jack.
