That's the thing, I can't eject a cd or insert one. When I press the the eject button, it gives the attention noise but that's it. The CD source isn't displayed on the screen. It's like it's non existent. Also, the parking brake wire is properly grounded.
I've installed one of these in my Mazda already. It works perfectly and what I'm experiencing now with this second unit is not a symptom of an installation-gone-wrong. I know what I'm doing.... this second unit seems to be having some sort of hardware issue. I can't see it being software related. Regardless of any version, the unit came with all the sources (CD, AUX, USB, Tuner, etc.)
I'm thinking I just got screwed. Any knowledgeable people want to chime in?
