We've seen all of these fancy add-ons like USB, SD and Bluetooth show up in all sorts of separate car stereos, but BOSS is the first we've seen to get up the chutzpah to throw them all into one stereo for the ultimate in nerdy in-dash entertainment. Thanks to our complete inability to read Korean, we're not really sure what these stereos, the 638B and P255B, do beyond the obvious, but the pretty pictures tell us that you can plug your USB phone in for charging and possibly other functionality, and that there is iPod functionality of some sort. Sounds good to us, now all we need is a car and we're set.
