The Short Answer

It's probably a combination of things. * The signal sent to an individual cellphone is probably much weaker than the one broadcasted by a radio station * the wavelength of radio signals is much lower, so they are less obstructed and probably have a longer range than a cellphone signal of the same strength * the antenna on your car is much larger than the one in your phone, so it is better at receiving Basically radios are meant to work at very long distances from the radio stations, while **cell**phones only need to work within much smaller "cells" around the cell towers so they are more easily disrupted
