"They were the only business that had exactly what I wanted at a reasonable price. It shipped immediately and works well."


Take any average USB Flashdrive (a.k.a. thumbdrive) and turn it into an in-car MP3 player. Simply insert the USB flashdrive into the FM transmitter which features buttons for play/pause, previous track, next track, and FM channel.

Unlike other FM transmitters, it plugs straight into the car cigarette lighter/DC power outlet, so no device power is used. The USB port even doubles as a charger for any USB device such as the iPod. iPod and iTrip (the leading iPod FM transmitter) users will agree that the iTrip sucks iPod power rapidly. This device will charge your iPod (using an iPod USB cable) while transmitting an FM signal.

The transmitter features an audio jack for your iPod, other MP3 players, CD player, DVD player, or whatever else uses a 1/8-inch audio output jack. An easy FM channel selector allows you to choose transmission frequencies in the lower FM frequencies. For best transmitter results, choose a station with weak to zero broadcasting in your local area.

If you have a cassette deck in your car and you want a seamless connection to your iPod for the best quality and control, try our assortment of Car Tape Adapters.
