I believe the newer Pioneer units are compatible with Apple Car Play. If I were in your situation I would check to see if you find that feature appeals to you. I think a double din unit would look better, but I may be biased on that issue because that's what I have. I think your AVH P5900DVD has a motorized screen and that will be blocking something in the Boxster center console.

I bought a refurbished unit when I installed my system and paid around $500. So, if you don't need the latest model, it won't be that expensive. I have a 6X40 amp from a 996 Cabriolet to power my system.

Here's a thread that contains information about my installation: http://986forum.com/forums/general-discussions/51283-does-anyone-know-vss-wire-02-bose.html

Good luck with your decision.
