I have and I would suggest other wise. The Flip out motorization is just more to go wrong. I have had many a systems, worked with some of the best in the industry and had nationally accredited vehicle. AKA The hummer I am in now. I first tried a flip out as well but the upper exhaust vents will blow warm and cold air on them which could effect screen quality. However the biggest problem witht he flip out motorization screens is even if the screen is mounted in the lower section of the double din the 6.5 to 7.5 inch screen will hit or contact the nipples on the breast looking exhaust vents. The only solution to this is to either lower the screen by moving the onstar, or ac controlls wich is not a great idea. the other solution is to bring the physical radio out more and therefore it leaves an unfinished look and big din hanging out. Unless you already have the single din motorized screen or are getting it for free or re-using from old system I would recommend a double din head unit with a screen. Also if you have to use a single din head unit they do make double to single din conversions. You probably have seen them already and didnt know it. It is usually a black plastic piece the size of a doulbe din but has a pocket/cubbie hole/compartment style slot that can either be mounted on the upper side or lower side of the single din.

Hope this helps
