Ok I have a 1996 GMC K1500. I have had two different aftermarket radios in the truck. I have swapped the antenna also. here is my problem. It gets very bad radio reception. Even when I am in the town where the radio station is based. If i drive into lower areas it gets worse. It is always static or poor reception. I tried looking on here for any info on this problem. No luck. If anyone can point me into the direction of a thread or some areas on the truck that may be the problem that would be great. Yes the antenna cable is hooked up to the radio. The radio worked great in another car it was in. Thanks for any help.
