My Boxster came with a very poorly installed fast and furious looking aftermarket single din head unit that didn't look like it belonged. I wanted something that appeared OEM but had more capabilities than the Becker stereo that the car had when it was new. My solution was to get a Chinese Xtrons double din Android head unit. As well as playing music it can also run GPS & OBD software (and any other Android app for that matter). The head unit has no tell-tale brand name on it's face and it was fairly easy to customize the interface to make it look OEM. I just completed the installation this past week and well pleased with the result.
