Belkin has announced a new FM transmitter for use in cars that features an iPhone application. The device is called the TuneCast Auto Live FM Transmitter. It uses the iPhone ClearScan Live software application to allow iPhone and iPod touch users to operate the FM transmitter directly from their devices.

The application also uses the devices to get GPS coordinates to find the best stations for broadcasting in the area. Belkin says that the device and App take advantage of iPhone OS 3.0 and is the first application to interact with an iPhone FM transmitter.

The iPhone app allows the user to find the clearest FM frequencies based on GPS data and results from other TuneCast Auto users in the same area. The app can manually change frequencies and set favorite channels as presets. The device will be available in early fall at an undisclosed price.
