WIRELESS CONNECTION TECHNOLOGIES
February 21, 2005 - While driving around, take a look at the number of people talking on cell phones, adjusting their mp3 player, or entering notes into their personal digital assistant (PDA). Do you ever feel they’re distracted and perhaps not paying attention to the road? With advances in technology, we are seeing an increasing number of these "electronic distractions." Recognizing potential safety issues, vehicle makers are constantly looking for ways to integrate your personal electronic equipment into the vehicle designs so they can be operated while keeping both hands on the wheel and attention focused on the road. One technology currently being integrated into vehicle designs is called Bluetooth. This article will explain how Bluetooth works, how to identify vehicles equipped with Bluetooth systems, how to determine if the system is damaged, and how to handle a damaged system. Bluetooth Bluetooth is a specification for the use of low-power radio communications to wirelessly link cell phones, computers, and other devices over short distances, typically an average of 10 meters (30'). Currently, Bluetooth is being added to vehicle designs to provide hands-free cell phone usage using the driver’s own cell phone, rather than one that is provided with the vehicle. However, to use this system, the vehicle owner must also have a phone that is Bluetooth enabled. These phones are readily available to consumers. Many manufacturers, such as Motorola, Nokia, Samsung, and Sony-Ericsson currently sell phones that are Bluetooth capable (see Figure 1).
How The System Works With a Bluetooth-enabled phone, the driver simply has to turn their cell phone ON. The phone links up with the Bluetooth module and the driver’s voice projects through a microphone. For factory-installed systems, the microphone is generally located in the rearview mirror (see Figure 2) and broadcasts through the vehicle’s stereo speakers. Many of the current systems that are factory installed are voice activated to maintain a completely hands-free system. Aftermarket kits are available for vehicles that do not have the option installed at the factory. These work in a similar manner, however the equipment design and location are different. The microphone is a separate piece that is not integrated into the vehicle design. The speaker is also separate, rather than operating through the vehicle’s sound system (see Figure 3). Vehicle Makers Currently Offering Bluetooth DaimlerChrysler has named its Bluetooth hands-free communication system UConnect™. It is offered as a factory- or dealer-installed option on the 2005 300C and Pacifica. UConnect™ uses advanced voice recognition that empowers you to dial your Bluetooth cell phone using simple voice commands (example: "Dial 123-555-1212" or "Dial Jane Smith at home"). Other current features of UConnect™ include:
Other vehicle makers also plan to offer Bluetooth technology as a vehicle option. The 2006 Saab 9-3 and the 2006 Toyota Prius both have Bluetooth as part of their offering. This list is expected to expand in the near future. Collision Damage While installed well within the vehicle interior, Bluetooth parts are still susceptible to collision damage. When performing damage analysis, first determine if the vehicle has a Bluetooth system. Indications that the vehicle may have this option include controls on the rearview mirror, or a separate microphone and speaker. This can be confirmed by looking at the factory options sticker or by asking the vehicle owner. Also, to verify if the system is working properly, ask the vehicle owner to make a phone call. If the system is not working properly, follow the repair flowchart in the vehicle service manual. Like most electronic parts similar to these, damaged parts may require replacement. Future Applications There has been speculation that Bluetooth technology will be included in most vehicles by the end of the decade and will be providing more than just cell phone hands-free convenience. Added to the technology will be mp3 players, where a Bluetooth-enabled mp3 player will play through your stereo without a wire connection. There has even been talk of integrating PDAs into your vehicle system. Who knows what else the future holds? Conclusion More laws are being passed regulating the use of cell phones while driving. Residents of New York, for example, cannot legally drive while holding cell phones and 15 other states are in various forms of similar legislation. The Bluetooth technology is a big step forward in providing a wireless, hands-free environment in your vehicle that creates safer driving conditions and helps comply with these new laws. With that being said, these systems are bound to grow in popularity. It is important to recognize this technology when it appears in your repair facility, so system checks can be made to verify proper operation before the vehicle is delivered to the customer.
