I guess I should further qualify my statement about reading the manual. I've read the manual (only once) about the v, but only glanced at the Entune manual/book. Just opening it up and looking at for a few minutes, my eyes start to glaze over. To know how to operate Entune should be as intuitive as operating the car itself.
I am in the process of reading mine. Need to figure out how to set the radio presets...as well as a few other things.
