The double-din head unit that I installed is a Xtrons brand that I found on e-Bay. It runs plain vanilla Android so it's easy to make a OEM looking background and even makes it easy to change the load screen to a animated Porsche crest. It doesn't have the Xtrons brand logo on its face so it's not so obvious that that it's a aftermarket unit. It has three USB inputs and has the ability to display a back up camera image. I like it a lot. Although a volume knob is a handy feature I wasn't able to find a head unit with a knob that looked like it belonged with the Boxster's other controls so I made a point of getting one without.
