I am basically in the same position as you are with my 2000 X5.

I am looking for a DVD and NAV unit that I can have that I can play movies while moving. I know , I know. It's not safe and no manufactures make them like that. But Pioneer has come up with the gyro sensor in them now to really throw a wrench in that.

Does the Z1, or the D3 have that sensor? Do you guys no what I'm talking about?

Hit me up with a message cause I want to be done with this decision so I can buy a unit.

Thanks Greg
