update about 2 weeks now and the bazooka still works fine !! the auto on/off worked, I saw on YouTube a co that makes a wire harness that goes between factory stereo hookup, then has add ons for rca jacks etc to add a amp etc. ,but it cost $260 plus ya have to take out the factory system to plug it in! this works fine so far. and sounds 100% better, its a shame the factory system, even the 8" touch screen and 6 speakers sounds like crap, from factory.
