At Boss Audio Systems, we've always thought outside the box. The 810DBI is as innovative as it is stylish. Imagine this-a Front Panel iPhone DOCKING CRADLE for your iPhone-3G, 3GS, 4, and 4S. Just detach the 810DBI Control Panel and attach your iPhone in its Docking Cradle to transport your Musical Library and other favorites into a Super System. Reattach the Control Panel and it's also got all the "goods", AM/FM Receiver, USB and SD Memory Ports, plus a Front Panel AUX input.
