Belkin has upgraded its popular TuneCast in-car iPod/MP3 sender, which takes the sound from portable music players and transmits it to your car radio. The new version, available now, has improved functionality and cable management, and sells for around £40 complete with in-car power supply.

The new TuneCast 3 has a status indicator to show when memory presets have been saved, when it's processing a request and when it's powering up or shutting down. It connects to portable devices using a standard 3.5mm stereo plug, so it can be used with iPods, MP3 players, PSPs, portable DVD players, notebook computers – in fact, anything with a headphone socket.

It can be set to transmit on any frequency in the 89.1-107.9MHz range, and has two presets to store favourite frequencies. The built-in battery has a 20-hour life, and it comes complete with a mounting clip and a power cord for battery-free operation.
