Has anyone tried installing this powered retractable sunshade? It looks like something that should have come with the car, but I'm hesitant to try installing something like this, especially since it requires routing a power cable through the trunk rubber seal. I'm worried that I'd do something wrong, or the cable wouldn't allow the seal to reseat properly. I have a perfectly functional, cheap, sunshade I got off of Amazon, but it isn't retractable, powered or otherwise.
