First thing I did was go out and check to see how it works with my USA Spec iPod adaptor in my 05 Tundra. Seemed to work well. I unfortunately forgot to test the mode that displays the song titles on the stock stereo. I just did the direct mode controlling the iphone directly. Charging feature worked as well. I'll check the the other mode later but now I'm just happy my iPone 5 will play and charge in my truck.
