I am missing something. Why do folks like Ford have a Sync platform that then bolts on CarPlay. And why would they then have a separate system for Toyota. I understand that there are other features that dontwalkhand points out that require CAN integration, but I thought that was what CarPlay was all about not just an App that rides on the AutoMakers system. Does anyone have significant knowledge about this topic to explain all the layers going on here?
Thanks!
I'm not an industry expert. I see it as pretty smart how the auto industry is
slowly adopting CP/AA and still developing their own systems. I also think it's damn smart to have CP/AA as phone extensions that
ride (pun intended?) on the car makers system. Their systems integrate with critical functionality. CP/AA should not have that type of integration, imo.
Why they still make their own?
1. They realize that vast majority of car buyers don't care about CP/AA. It's too new. Heck, even on tech savvy sites like MR a lot of people still don't actually know what CP is and what it does and does not do. The number of people who want a car to have CP/AA vs the number of people who want a car is pretty small... right now. Since it's basically an overlay, they can give people CP/AA and still have their own for those who don't care. Choice is a good thing.
2. Update issues. The auto industry doesn't change the way the tech industry does. How many times over the life of a car will CP/AA be updated? How will those updates affect the function of the system? How will those updates be implemented? USB drive from a dealership? from home via iTunes? wireless update via phone? What if an update borks the system. Several iOS/Android updates did that to mobile devices recently. That's annoying on a phone, but potentially dangerous on a car.
3. Continued improvement. They all have their own ideas about what makes a good system. Not every idea is a good one. Like any industry, they borrow what works from their competitors and add it to what they already have. The industry moves forward. Just like they're going to look at CP/AA and see what works with those systems. They'll take what they consider to be "the good" and leave the bad and the ugly.
