After the last long-winded post, here's a companion post, also highly customized to my own particular setup. I have the magsafe wallet on the back of my iPhone, and have to take it off to put it into the above phone holder, and needed a place to put it. So I made a simple tray that slides into the mostly useless slot under my single din radio dash adapter. I'm not sure which adapter this is since the PO added it (likely Metra?), but if you've got the same one and want to make the slot under your radio slightly more useful, here, have this tray. It doubles as a convenient place to hang my sunglasses.
