I purchased the iSimple GateWay ipod/iphone adapter after they assured me it was now proven compatible with the 2006 STS. I have factory radio with 6 CD changer but no Nav. Installation appears to be simple, but I cannot figure out how to get the dash panel off to get to the back of the radio. Does anyone know what has to be removed? Does the wood trim have to come off, or just the black trim around the radio? I understand it clips in, but where are the clips located and what kind of tool is required to remove the trim? Pictures of the trim after removal would help. Thanks.
