Has anybody found a way to fix the poor radio reception?

 

LarryD,

If you can access the antenna connector at the rear of the radio, get any old car radio antenna and try it. Clamp the antenna mount metal-to-metal to a solid bare-metal ground somewhere on the car. If the antenna swap fixes things, then you have an antenna problem. If so, then you may have a a dirty cable connector into the radio, or a bad connection at the far end of the antenna cable. Radios need good grounding, at the radio body, and at the car chassis. If a different antenna and solid grounds do not change things, all that is left is the positive power line and the radio itself. If clean power (jumpered straight from the battery into the radio power wire) fixes the problem, then the car wiring is at fault. If you can (temporarily) swap in a new radio, maybe a better quality radio, that may also be an answer. Hard to nail it down, from what you said here.
