The iPhone works beautifully with Bluetooth car kits, too. The pairing procedure
generally goes exactly as described above: You make the car discoverable,
enter the passcode on the iPhone, and then make the connection.
Once you’re paired up, you can answer an incoming call by pressing a button
on your steering wheel, for example. You make calls either from the iPhone or,
in some cars, by dialing the number on the car’s own touch screen.
Of course, studies show that it’s the act of driving while conversing that causes
accidents—not actually holding the phone. So the hands-free system is less
for safety than for convenience and compliance with state laws.
