Hello all, planning to get an x this Thursday, and would really like the motorla car dock, but I have a troubling question. Does this dock have a dedicated 3.5mm audio out Jack? I would really like to keep the audio Jack connected from the dock to my trucks stereo so that all I have to do is slip the phone in the dock and drive. This seems like something that should be standard, but it shows no information on the motorola dock page. Thanks all!
