I installed an aftermarket GPS. I went with the new Audiovox. It has all the features the Alpine and Pioneer at a lot less cost. I don't know who you priced the Alpine at but that sounds cheap.
I don't have pictures but I mounted the screen on the front of the overhead console (I have the moonroof). The Audiovox screen is a 16X9 aspect ration so it fits and look great. The remote is backlit and sits just left of the center console so when you have your hand on the Shift you can comfortably dial in your coordinates. The remote also come out so your passenger can use it also. The brain is under the back seat.
I have used Alpine, Pioneer and Audiovox and for what it's worth, if buying again I would stay with Audiovox.
