Hello, I have an 06 is350 with the ML system. I have noticed that when I play/stream music from my Iphone via the lighting cord/aux the volume is diminished. This also seems to be an issue on my 08 tundra limited crewmax with the JBL system. So I am assuming that it may be a setting that I am overlooking on both systems. I have verified that my phone is up all they way and that the cords are in good working order. is there an easter egg setting I am overlooking? similar to the blue tooth volume setting?

thanks and I will search as well.
