Audio upgrades are a huge PITA in any modern Porsche. Communication between modules is via a fiber optic network, you can either get an expensive adapter box or just scrap everything. The dash kits also aren’t very elegant, they are a wart in an otherwise nice interior. If you don’t care about the awkward looking head unit the easiest and best approach is to just trip out the entire factory system and replace everything down to the wiring.
