A huge benefit to CarPlay for me is I can travel someplace like Japan, get a car with a CarPlay-supported head unit, and immediately I have Google or Apple Maps available straight off the bat in English with all my saved locations like hotels or places that are bookmarked. Nothing to set up or anything.
The only downside I've experienced with it in Japan is the GPS can be wonky in tunnels whereas the car's built-in GPS seemingly doesn't.
- hedgehog 2y agoThe car probably has odometry and inertial sensors to do position updates while GPS is unavailable. That's actually how some of the original car nav systems worked even pre-GPS in the 80s.
- spike021 2y agoThat makes sense. I would've thought the accelerometer/gyro in the phone could be used similarly but I'm probably wrong.
- astrange 2y agoIt can, but it's harder because you can mount the phone any way you want in the car, or not mount it at all.
- SkyPuncher 2y agoI strongly doubt that. Cars simply have bigger, more power antennas because they don't have to be packaged in a phone. One of our cars has a wireless modem that can be used for a hotspot. I've driven to plenty of areas where my phone has no service (think remote and hilly terrain), but the car still has two or three bars.
- hedgehog 2y agoThe sensors are there and report on CAN bus, I just don't know enough about how the nav systems are integrated to know if they actually use the data.
