check the battery voltage....should be 12.5 volts and the age should be newer then ten years old...the connections should be free of corrosion...disassemble and wirebrush them clean~ check the ground connection at the radio~ think about your troubles are related to the ground of the car....one insufficient voltage, chassis NOT grounded....good luck...you will find the trouble..it's ground related~
