XtremeMac today announced the release of AirPlay, a new FM transmitter designed especially for Apple’s iPod and iPod mini. The company says AirPlay is the “first and only iPod-powered FM Transmitter that works across the full FM frequency band without the need to install software.” The compact transmitter works universally with all dock-connector and click-wheel iPods and features an easy-to-read illuminated digital frequency display, which turns off automatically after tuning to conserve iPod battery power. AirPlay is available for the suggested retail price of US$39.95.
