We suspect the whole "iPhone-friendly" bit is more marketing hoopla than anything else, as Kenwood's I-K50 head unit definitely lacks a straight-up dock connector, but that doesn't mean it won't play nice with Apple's latest handset. Boasting a USB port right on the front, the single-DIN deck gets down with iPods, iPhones and practically any DAP or PMP with a USB connector. Of course, it also supports those antiquated discs we Earthlings call "CDs," and the front-mounted auxiliary input makes it really easy to connect any source with a headphone output. It's set to drop in around a month in Japan for ¥23,100 ($259).
