Two small questions about radio reception and the exterior mirror

Hello, I have a Colt 6. The radio is not an original, the reception is very bad, it fluctuates, the radio often tries to find the transmitter new. Do you have an idea where to look first? My second problem is the right electric exterior mirror, it doesn’t drive far enough inward, the motor drives to the “stop ” and stops. But he could drive a little more inward for me, someone knows the problem of you. MfG Jo
