Having my car done this week. Dealership recommended Bluetooth Valet here in San Diego. Read the other posts and talked to the owner Greg Gattuso (760-670-5078). Cost is $300 to add a circuit board that overrides the cars monitoring system to confuse it into thinking the car is at a complete stop. Allows you to access your phone features and navigation features while the car is moving. I am told it has no effect on the other functions of the car. They also install a rocker switch in the center console (can't even see it) that allows you to disable the override returning the car to normal factory function when you want.
