I run a business out of my truck & home, mostly from the truck. My old phone, a Motorola E815 had a "cradle" in the truck, which when the phone was attached to it the incoming call could be heard via an auxiliary speaker under the dash. With this new Droid 2, and it's cradle, I cannot hear any of the incoming calls. Does anyone know of a way to attach an external speaker to this phone while is is docked in the truck? Thanks, David
