It does sound like a lot, but I can only speak for MY2011 and beyond. But assuming there's little difference to MY2010, installation is time consuming. To install the hitch, the rear bumper cover must first be removed, then replaced once the hitch is in place. Then an OE electronic towing module must then be installed, followed by the wiring for a receptacle where you plug in the trailer connector. To establish necessary towing settings, the car has to know when there's a trailer attached. Plus you'll need a brake controller. Once all this is in place, plugging in the trailer electrical connector tells various car systems that a trailer is attached - and they reset appropriately. Doing so also connects the trailer brakes to the brake controller.
This is required for liability reasons. Porsche says you need a brake controller for any loads over 1650 pounds (to include the trailer). Assuming your Curt hitch is in the 6000# range, the dealer has to perform an installation that assumes the capacity of the hitch. If you only want to haul something like a bike carrier, you can have a body shop do the job. It's just bumper cover off, hitch on, bumper cover back on. But you have to let a subsequent buyer know that the hitch installation isn't rated for anything heavier than 1650 pounds. Otherwise you could be opening yourself up to legal problems.
