It also occurs to me that this decision is probably affected by the model of Porsche that you own. They're all great vehicles.

However, I'm MOST familiar with the pre-owned 911 market, where OEM is very highly valued and commands higher prices. An aftermarket HU would be a turn-off to many potential pre-owned 911 buyers, but a fully functional PCM modified with a perfectly functioning CarPlay solution would be desirable.

These kits are made to work perfectly with the existing PCM system, giving you a factory-like CarPlay experience. Brands like JoyeAuto, Naviplus, and Car Solutions offer these kits, which keep your car's original look while adding modern features.

The same applies to the PCM modification solutions, but folks are less likely to want to make the change since it already provides AndroidAuto and CarPlay with a fully functional OEM PCM system. If they value OEM, why would they change something that isn't broken?

Why do you care so much what other people have installed into their cars? Enjoy what you have like we are enjoying what we have.

The PCM maps may be several years out of date, but the main roads aren't out of date and they pre-date the GPS system.

Apps like Google Maps do allow you to download maps for offline use when there is no cell connection (GPS still works on a phone with no cell signal), and the maps are always up to date because 99+% of the time you do have a cell signal and the maps update in the background with no human intervention necessary. Since Waze has been owned by Google for close to a decade now, those maps are updated frequently as well.

Again, I see no upside to the aftermarket head-unit approach except for a slightly larger, and higher resolution screen. However, I'm not watching movies, I'm enjoying driving a remarkable sports car and glancing only occasionally at a map or a music app play screen. Moreover, I do see more downsides to turning the PCM into a paperweight.
