If you are driving a car that didn’t come with the fancy Bluetooth hands free kit built in don’t fret, you can still use your phone hands free and get caller id info too. This rearview mirror takes it to the next level by integrating caller id info into the mirror itself.

With this mirror and your Bluetooth phone, you can place, receive, end, redial, and adjust speaker volume at the touch of a button. Your phone is supposed to connect to the mirror as soon as the car is started.
12-volt power is required for operation and a USB port is integrated for firmware updates. A mic with visor mount captured your voice and a speaker on the back of the mirror allows you to hear the caller. 12-volt power is provided via a cigarette power adapter. The mirror is available now for right at $170. Image via Gadget Box
