No though I could do so. The IMA supplies the car when the auto-stop comes in and also at idle. Voltages vary between 14V and about 12.8V depending I think on the actual charge of the 12V battery. I agree with a previous post auto-stop can be a little odd at times, working sometimes, others not.Yeah an android head unit would be far less of a hassle than a "normal" head unit. Have you checked the power draw of the head unit at idle just to be sure it's not draining the battery?
