Focal is a good choice. I had the 165
VB's in the Lexus and they are great. Head unit choices are a bit more difficult. In my experience, I would stay away from Alpine. Generally, their designs are gaudy with oddly shaped buttons and back-lit buttons that only come in eyesore shades of blue.
My friend and I were both installing touch screens in our cars at the same time. He went with an Alpine and he regretted it. The on-screen navigation is clunky and to pick a song on your ipod, you had to scroll through your artists or songs ONE AT A TIME. It takes forever. Also, his bluetooth never worked and it sounded like you were in a tornado.
I always do my research and went with a full touch screen Pioneer. It is great. Navigation and song selection is quick and easy and the buttons can be changed to any shade to match your interior (if that matters to you). I would definitely consider one of the new Pioneer units.
