Griffin iTrip DualConnect
Griffin rarely builds iTrip FM transmitters without their own integrated screens for FM radio station tuning, but the new iTrip DualConnect ($60) takes a semi-new direction for the company: it's a universal "play, charge, and control iPhone or iPod touch through any car stereo" design that can be used as either an FM transmitter or an auxiliary audio out device as needed in a given car. This combination of features is useful for frequent car-renting travelers who aren't sure what sort of stereo they'll wind up with. The FM transmitter features of iTrip DualConnect are only accessible through Griffin's free iTrip Controller application, and thus limited to iPhone and iPod touch devices rather than the broader array of iPods, but the auxiliary features work with all Dock Connecting iPods released over the past five or so years. Integrated reverse, forward, and play/pause buttons on the charging bulb provide control over tracks even when the touchscreens are turned off, and glow a bright white thanks to LED illumination when the power's turned on. Sound quality on empty channels is also quite good.
