It was bound to happen eventually and, in fact, it's surprising that we haven't seen this sooner.
Blaupunkt's "Melbourne SD27" is the first car stereo that shuns CDs, according to SCI FI Tech, instead playing MP3 and WMA files with a front-loading SD card. To make things even easier, there's an optional adapter that can be used for an iPod, mobile phone or GPS device.
The writing was already on the wall for car stereos to go this route, but the kicker that could accelerate the trend even faster is this gadget's price of only $160. That's got to be one of the lowest entry prices for any major first-mover tech product we've seen in years.
