X5-RWK - I like Pioneer too! I have only purchased their units since I was a teenager.

Kryptonite - That is one heck of a list. I want the front and rear cameras also. I prefer to have a split screen to show them both at the same time however that video switcher you mentioned may be a good option. I'll have to check it out.

One other thing to watch out for with the Z1. The Z1 does not have a negative tilt feature like the Exclipse units. The owner's manual says do not installed the unit beyond 30 degrees vertically. In the X5 our dash opening looks to be 40 to 45 degrees. In the daytime my screen colors wash out a little because of the angle. The night time screen is perfect.
