FYI, The seller is a fellow forum member. GREAT people to work with. They will do pretty much anything to keep their customers happy. (I am not affiliated with their business at all, just a happy customer!)

+1, that is the route I went on my 2004 Boxster S with MOST BUS. I got the Kenwood 7140 with bluetooth, GPS, Sirius & and a back-up camera. All are significant upgrades from the factory Porsche products in my opinion. Porsche makes great driving cars, but their technology tends to run light years behind some of their competitors.
