We’ve been hearing about it for months, and today it’s available for purchase.  The newest generation TuneCast FM transmitter, dubbed the TuneCast Auto LIVE, works together with a partner iPhone app [iTunes Link] and the iPhone’s GPS unit (3G & 3GS) to find the best FM frequency for your area.  You can also control the transmitter via the iPhone app, a feature added in iPhone OS 3.0.

Other features include a high-contrast LCD display, a 12-volt cigarette lighter adapter (which powers the TuneCast and charges your iPhone), programmable presets and more.

If you’re wondering, this latest TuneCast is model F8Z498. There are several TuneCast products, so be sure to check the model number if you want the latest generation.
