http://x-shade.com I was seeking for a solution that will cut down some of the sunlight going in to the back of the auto when i was carrying out a trip with my children and what i purchased was the X-Shade and i'm quite impressed with that solution, this is how it comes and you merely take it out of the package and it type of unfold itself and it comes with this tiny suction cups that is quite ease to place correct trough the hole, ok, it really is in the middle , there you go, and it merely attaches to the window like this , and when i first saw it i didnt think it really is going to perform , you correct by means of it , but it does perform really nicely . it really is cut down the sunlight glaring in to the auto, the glare that is on the DVD screen is gone and it really is leave the auto a tiny bit cooler , so quite good solution i very suggest the X-Shade
