Has there been anything new done to these besides the volume knob moved closer to the middle? Has pioneer worked out the grounding issue on the RCA's? I have a 7600 in one car, and a 6500 in the other, and both are awesome units. However, they do have the grounding issue that makes the whine. My wife and i just got a new car, and i love the pioneer sound. Any advice would be great. Thanks!
