If you’d rather be Macgyver than buy a holder for your cell phone, you can outfit a binder clip to place your phone in between your car air vents. We posted detailed instructions in 2011 for taking apart the binder clip and prepping it with duct tape, string, and a rubber band. Once it’s together, clip the binder to the car air vents and use the metal loops with a rubber band around them to secure your phone while you drive.
