Belkin has revealed TuneCast 3, the latest model in its range of FM transmitters for iPods and other devices.

TuneCast 3 offers a new status indicator that lets users know when a memory preset has been saved, and offers a 20-hour battery life.

The device will stream audio from any device that's equipped with a 3.5mm headphone jack.

TuneCast 3 is expected to ship in November and will cost £39.99.
