I never been so frustrated with a vehicles audio like on this Nitro. I never left a factory radio in any of my car's but I just may on the Nirto. I've read many of success story's here. Mine not so much. It's with noise.Noise,noise and noise. A buzzing noise through the speakers actually. Buzzzzzzzzzzzzzz. Radio,cd, volume down,volume up. To go as far as having only power,acc and ground wired up. Nothing else wired in. Can It be the radio itself? I have the Metro harness. One more thing. The radio likes to turn itself on and off too. Happy 4th.
