Oh... funny note. I read all the reviews of the JVC on Amazon: There is always one in the crowd. This guy complains because 10 days after he had the radio installed "professionally" he could hear a buzzing that got louder and higher with the engine
We know what that is.
Then he said that the installer put something in there to make it stop, which worked for a day. Then a lot of other things started going out, and he had the same problem with 2 units... DUH!
