You could go the CPT 9000 route -- but it won't be bluetooth. That integration is "wired" in that in order for the car/phone integration to work, the phone MUST be plugged into the phone cradle in the center armrest. People like the Bluetooth integration because you can literally leave your phone in your briefcase / pocket / purse/ etc. and still answer and make calls via the car. You can also transfer calls easily between the phone and the car as you get in/get out at your destination. Also, you can easily upgrade your phone later to most bluetooth capable phones (note "most" vs. "any" as there are some incompatabilities). The CPT option is a fine way to go, it just gives you materially less flexibility.
