Today's iPhone tip explains the easiest way to go hands free in your car. You need 4 things to make this happen: An iPhone, a car with an 1/8" stereo auxiliary input, a Phillips iPhone Microphone Adapter, and a 1/8" to 1/8" audio cable. Plug one end of the audio cable into your car's auxiliary input, plug the other end of the audio cable into the iPhone microphone adapter. Plug the other end of the iPhone microphone adapter into your iPhone. Clip the microphone to your seatbelt chest strap, set your car stereo to the auxiliary source input, and you are ready to go hands free. Select some of your favorite tunes from your iTunes library and it will start playing through your car stereo speakers. When a call comes in, answer the call by pressing the button on the iPhone microphone adapter. The music will automatically be paused, and you will hear you callers voice through your car stereo speakers. You can end the call by again pressing the button on the microphone and the music will automically resume. For $15 in additional parts, and about 3 minutes of time hooking things up, this is an extremely simple and effective way to go hands free while driving with your iPhone.
