text: Another useful gadget is called the "Motorola Roadster Pro In-Car Speakerphone". If you really don't like the idea of having to pull your phone out of your pocket or purse every time you get into the car to secure it to your dash or windshield, however, and you don't have Bluetooth hands-free calling integrated into your car's audio system, there is another class of gadgets that will serve you well: the two-way Bluetooth in-car speakerphone. These devices typically clip to your sun visor, though some mount to other locations, and act as a traditional office speakerphone, except that they're linked to your cell by Bluetooth, and they're in your car. This means even cars without integrated Bluetooth can have the comfort and convenience of hands-free calling without ever touching your phone at all.
