Deetz, all of the above are possible. I have a Cayenne here now that has it done. Keep in mind though that you no longer have any check engine lights, ect, ect. When you are going into the cluster you eliminate the whole display that is currently in there. It is def. cool. But not without some sacrifice.

 

Holy Cow!!! That looks awesome!!!

 

The guys at By Design in Los Angeles have done many of these. The NAV screen is shared with TV, DVD and the 4" monitor in the cluster, (Turbo) becomes a rear camera automatically when you shift into in reverse or can be switched on manually when desired. They also advise me that this mod. will not effect the present displays, (you will lose the Porsche pop up logo) or create any error codes in the computer.
