I installed an XTRONS unit in my old 997.1 which worked well and also included Apple Carplay and Android Auto over Bluetooth along with all the standard functions. It's touch screen only thought so I also installed the remote controls that attach to the steering wheel for better access to volume control. There were a few niggles though as the install instructions weren't the best but overall not the hardest process in the world. The only other issue was slight interference from the engine but that's relatively easily fixed with the addition of some old fashioned suppressors.
Here's a link to the unit from Xtrons (included a MOST adapter for the BOSE amp although you lose the ability to fad front to back):
