Similarly, if you are using CarPlay, it will use your car's GPS instead of the built-in one. I figured this out when my car's GPS developed a fault which often gave a lock hundreds of meters away from my actual position, and my phone did the same thing when connected via CarPlay.
- the_mitsuhiko 4y agoCars also do dead reckoning with wheel and steering data so you get pretty decent data in tunnels where basic GPS fails.
- _rs 4y agoCould you expand more on this? Very curious what this means/how it works
- parshimers 4y agoMost headunits with Carplay require you to have the vehicle speed sensor connected to them. They also have a compass. So, if you lose GPS, you have the 3 components you need for dead reckoning: A starting location, a heading, and a speed. It works pretty good even in complex areas like parking garages.
- tiernano 4y agoDoes not seem to be the case for bmw g30/31 (5 series). The onboard satnav works in tunnels and does not think I'm driving down a side road, but CarPlay does...
- _rs 4y agoHmm, there must be a lot of cars without their own GPS then, or maybe apps can choose to use it or not? When I use Waze with rental cars I often see Waze responding to my phones orientation when CarPlay is active. Unless Waze is using orientation just for visual and the GPS is used for the position
