After your fourth or fifth time ending up in a ditch or a swimming pool or a tree while attempting to find a good FM frequency to push your iPod tunes to your car stereo, you're likely looking for a better way to live. Lucky for you, Belkin has been hard at work over-engineering the problem to death, and has finally emerged with the new TuneCast Auto Live FM Transmitter. The device is "specifically compatible" with iPhone OS 3.0, and pulls GPS data from the phone to figure out the clearest FM frequency to use based on "geographical" data and on the recommendations of other local users. It's all controllable from the iPhone interface with the free ClearScan Live app, which reduces device juggling, but the unit also works with the iPod touch, iPod classic and iPod nano. It'll be available early this fall for $80.
