Hello, I am new to the forum. I have 2 Mercedes, 2004 ML350 and a 2005 E500. Maybe you can help me diagnose a problem that I am having with my sound system in my ML350 It has the navigation system and the 6 CD changer in back. Recently the sound system started making a popping sound and cutting out. Sometimes intermittently and then it would go completely silent except for the popping noise. Then later after turning the car off and then back on again it would work for a little bit and then start popping again. The navigation stiill works fine and the interface works switching back and forth between each function. Also the popping noise continues even when the system is shut off. The only way that I stopped it from popping was to disconnect the smaller top plug of the 2 sets of wires that plug into the back. I have inspected the plugs to see if there are any loose wires but they all look good. I also pulled out the amplifier and checked the plug on that also but they look OK. I am at a loss now as to where the problem is. I was thinking the amp was bad since the noise continued even though the unit was unplugged. any help would be greatly appreciated.
Thanks,
Tim
