Possibly a VERY stupid question here. I live in MD and starting on Friday our state is going hands free...no holding a phone while driving. I have a bluetooth for my old phone that I could dig out, but I was kinda hoping to be able to pass that along to my hubby. I have the original Droid and I know it has a "Car Mode". If I buy a mount for my car, and put the phone in Car Mode, I know I'll probably have to touch the screen on the phone to answer the call, but will it automatically use the speakerphone?
