Automotive makers like FCA is still sticking with QNX and Harman made headunits hardware for many years. Having programmed on them, it was a pain with so many constraints while we have watches 100x more powerful than them. While the UI/UX and performance of headunit telematics apps are not the forte of automotive manufacturers, they need to change with times. Headunits are still marketed as an add-on with which the manufacturers can up the price by several thousands. While too much of an entertainment system on a car is a distraction even though they have speed lockouts, a little bit of improvement will be a welcome change. Its not that they should have APIs for CAN Bus access, but can piggy back on CarPlay for a good music & nav system.
