Thanks, I bought the Caddy parts used from eBay for a steal. I then removed the screen and made it fit the Ipad mini (removable). The other dash parts were cut and glassed around the pop up portion. I then added a touchscreen satellite radio tuner and custom Touch screen HVAC controller. Also have Plx Devices touch operated gauges. I also had to reroute the HVAC vents to work with this setup. As far as how it operates, I stripped the unit down to its most basic function which is a 12v motor that reverses polarity to move it up and down.
The performance app I use is DashCommand with my own custom dashboard.
