Bluetooth as it relates to cellular communications and hands free functions: Bluetooth capable cell phones and data devices like Treo and Blackberry devices can use bluetooth capability to communicate hands free either by using a bluetooth headset or bluetooth hands free car kit. The bluetooth headset will allow the user to hold a cell phone conversation without having to touch the phone or connect the headset to the phone using a wire. Hands free communications are virtually automatic in vehicles that have bluetooth stereo systems. A person can simply link his or her phone to the stereo and cellular voice communications will take place through the car stereo speakers and built in microphone in the vehicle. One does not need to purchase a hands free kit and have it installed into the vehicle to have hands free capability. For vehicles that do not have bluetooth capable stereo systems, a bluetooth hands free kit can be used in place of a traditional hard-wired hands free kit in a vehicle. Bluetooth in car hands free kits come in two forms; simple "plug and play" kits that incorporate the bluetooth circuitry, speaker and microphone in a single body that is usually plugged into the cigarette lighter and "install type" hands free kits that have separate junction circuit box, speaker and microphone. The difference between these two types of kit is that the "install type" hands free car kit usually has better voice and microphone quality than the "plug and play type". |
