You will notice a one- to three-second delay after you plug the connector into the iPod. While it's nice (and uncommon) to use the iPod's display for tuning, it can get in the way of normal navigation. This reviewer prefers a dedicated display. The in-line cable design (it's common, and one advantage is that it offers a low profile) allows passengers to control the iPod, but it can be dangerous for the driver to use while driving. In general, we prefer some kind of dock to sit the iPod in (like DLO's TransPod) for a heads-up view.
The device can be tuned in odd frequencies (88.1, 88.3, 107.9). Sound quality and signal strength rate on the mid-to-high scale; at our most open channel (San Francisco's 88.1), we got good sound reproduction with occasional patches of slight static. In some parts of the city, though, we got a good ounce of static and distortion. You'll get the best results by stretching the cable out. While it wasn't the best we've heard (try the DLO TransPod), it does pass our audio standards. However, twice in one weekend of use we experienced a glitch wherein our iPod froze on the frequency screen. Music continued to play, but we couldn't navigate our iPod until we unplugged the dock connector or powered the unit off.
Overall, the unit's ability to beam iPod metadata to a car stereo is a cool trick, and we were satisfied with the quality of sound. The difficult design of the base unit and the unit's iPod software bugginess should be called out, especially if the iPod screen freeze is a widespread issue. You should also note that the unit has no audio line in for other audio devices, and that you could also either get a transmitter that holds your iPod up (so that it's readable like a car stereo) or find a more expensive integrated solution offered by many automakers.
