If you own or plan to get a Bluetooth enabled cellular phone, you must get a Bluetooth car kit so you can safely use your phone wirelessly while driving. We have Bleutooth car kits that are verly simple, some that look like there are factory installed, others with their own display so you can see the call data and will display your phone number listings and even some that will stream audio wirelessly from your Bluetooth enabled mp3 player. Starting in July 2008, it will be illegal in California to drive your vehiclee while holding your cell phone to your ear. You will be required by law to use some sort of handsfree device while driving.
