In the photo in post 8, you can see my Boxster with a second head unit installed in the lower console. I used an in-line FM modulator to get the signal to the CDR head-unit so the MOST crap could stay in-place. It was tolerable, and allowed me to use satellite radio and my iPod (I wired the iPod connector into the center console). It worked fine. I did not have the money to go the double-din with new amps and speakers route, but it would have been my preference.
