"Aftermarket infotainment and stereo solutions for cars have largely died off here in the US. Innotrends has cooked up an Android-powered box, called Ca-Fi, that might have you wishing this little in-dash computer could find a home in your vinyl-covered panel. The 1.2GHz chip inside pushes Gingerbread to the 6.2-inch touch screen for pulling up directions, playing tunes and performing searches using the integrated 3G radio. Of course, as ExtremeTech points out, the double-DIN slot used by the Ca-Fi has been largely abandoned by car makers (particularly in America). But hey, if you've been looking for a way to spruce up that Nova rusting away in your garage, this could be it. We just hope you're the patient type -- Ca-Fi isn't expected to launch until Spring of 2012 and will be a Europe only affair at first. Head on after the break for one more pic and some PR. "
Looks interesting, I might get one if and when they come out.
