1. I have found the Pioneer AVIV 8000NEC on amazon for $915. Is this a legit source? Authorized dealer? It says it is sold by Crawford's Superstore. When I click to find out more about them, they don't seem to have much of a presence outside of Amazon. I dont want to get it and it not be legit, although it would be nice to save $400
2. With an after market head unit how are the vehicle system settings displayed? Do they get displayed on the head unit some ow? I know there is an input for a camera, but does will it auto matically display when put in reverse?
3. Essentially, do I lose any major functions by going to an after market head unit such as the one mentioned above?
4. What is a non-JBL Entune with NAV unit worth if taken out?
