There's a wealth of information on car-store.com. If you have the Bose, with fiber optic to the amplifier, then you will need to replace the amplifier as well to interface to the existing speakers, or do some kind of custom installation.

My car, 2003 Boxster S, with Bose, door speakers, no navigation, is going to have the head unit and amplifier replaced this coming week. I really wanted Apple CarPlay and a nice display.

I spent lots of time researching how to get a better head unit, but I was continually led to the need for head unit/amplifier replacement, and a wiring nightmare.
