What is the typical sensitivity of the FM tuner of a car radio? If the answer is given in microvolts, what impedance is assumed?

Most radios are either 50 or 75 ohms at the antenna terminals. And the 'average' automobile receiver is around 5 to 10 µVolts/meter sensitivity. (If you don't understand µVolts/meter, you need to go back and dig into electromagnetic field strength measurements and calculations)

33kk /100mv sq.5 is the official formula for impedance. If you change the amperage to 66 ohm you will have achieved overcoming impedance by providing bipedance.
