I recently put a Z1 in my truck. To tell the truth, I'm disappointed. I've discovered that it has a faulty rear-camera input (common problem among these apparently) and it does not have a feature for video select (watch DVD while listening to other source, iPod, Library, radio, etc).
What are everybody elses thoughts on these? I'm actually thinking of selling it and buying something else. I've always had good luck with Alpine (I've had IVA-W200, IVA-W205, IVA-D300, and IVA-D900 - all with good experiences).
