Hello DrCactus,
what other after market HU will you recommend? There is nothing after-market that will fit to the Porsche MOST-Bus system. The only thing that will fit plug & play is an old school Porsche PCM2 system.
Hello Muskoka Minute,
no after-market system will fit plug & play, except the outdated Porsche OEM ones.
So you have to do your own wiring of the system and add some CAN-bus modules to get the Alpine run properly.
Or simply ask you wife for an next birthday present that will be a professional installation of the Alpine by a professional car-hifi shop. But you know what could happen to your life if you ask your wife such things.
Sorry for the bad news.
Regards, Markus
