I leased a 2005 Audi A6 today. I was amazed at all of the gadgetry that they are putting into cars. Of all of the cool buttons and levers in the car, one of the coolest for me was built-in Bluetooth integration which allows me to make and receive phone calls through my car stereo.

Let me describe how this works. I started the car and turned on Bluetooth on my Treo cell phone. I clicked on "setup devices" on my phone and it automatically found the Audi's bluetooth connection.

Within seconds, it recognized my cell phone.

I used my phone to call my wife at home. After a brief delay, the phone call showed up on the car's main screen, my CD stopped playing and I heard my wife's voice on the car stereo speakers. It was beautiful. Even cooler was when I ended the phone call by pressing a button on my steering wheel and my CD continued playing from right where it left off.

I can't wait to go for some more car rides so I won't have to fumble with my bluetooth earpiece anymore. I love it!
