I went with the Dynavin unit. So far it's a good unit. And other than having to modify the mount, was a pretty plug and play affair. I didn't like the no Sirius thing, so I mounted my Sat receiver in the sunglass holder compartment. Also installed the Spec dock and a remote usb aux plugin in the center console. It was a pain hiding al the wires, but I think it was time well spent.
Next will be the rear backup cam.
