Other handy cellular accessories for your car include phone mounts that attach to your window or dashboard, and FM transmitters that let you listen to streaming music or music stored on your phone over a car stereo system. And, if the cell phone signal is not strong in your location, choose from a variety of signal boosters to enhance your cellular signal and help prevent dropped calls.
