My car's built-in navigation can do things Apple CarPlay can't, like HUD, dashboard mapping, dead-reckoning navigation in tunnels, fuel management, etc.

...until feature parity. Soon Apple/Google will be able to integrate with those features too. Aside from "dead-zones", I'm sure they will eventually have more integrations with car interfaces.

Even so, both Google and Apple seem to predict your location when signal drops. Somehow I still get decent navigation when I am in the middle of nowhere Iowa and have no cell service. Obviously the maps are cached, but somehow it knows I'm still moving. Must be accelerometer and gyroscope? IDK

I'd really like dash HUD integration with CarPlay.

GPS has nothing to do with cell signal. GPS is it's own signal from satellites that your phone has no problem receiving in a place like Iowa. In fact Iowa has a lot of things going for it to enhance GPS receivership - it's flat so you can see most of the sky, it's open - there's just not a lot of vegetation to absorb the signal coming from overhead (e.g. trees), its in the middle of the US which means there's always going to be 4 or 5 satellites with a line of sight to your phone.

It’s a $200 solution that has to compete with ‘good enough’. That’s really hard and they aren’t making it work.
