The Steering Wheel Bluetooth Adapter attaches to the inside of the steering wheel and can be adjusted for different sizes and fits. The gadget includes a microphone and speakers, an LCD display, an SD port for MP3s, a USB port and an FM-out to play everything through your car’s stereo.
The adapter still needs a power source, which is why it hooks up to the cigarette lighter by wire. As Gizmodo points out, this seems cumbersome and perhaps dangerous to have a wire leading from the steering wheel to the dash. It works from a rechargeable battery, but when would you recharge it except for when you’re driving?
KickingTires seconds the sentiment: How does this work in the real world? Our best guess is that you charge it at home and take it with you in the morning. Hope a single charge lasts a long time.
