I have used the My-Route-app in combination with Apple CarPlay and I experienced that the app requires both screens (Smartphone + CarPlay screen) to be visible and active during navigation as essential information is missing on the CarPlay screen and it is impossible to start the route from the CarPlay screen.
In order to use CarPlay in my car, I need to physically connect it to the USB socket in the center console of the car. As such, the Smartphone is stored in that center console and only the CarPlay screen is visible for navigation. That means that e.g. speed limits are not visible on the CarPlay screen, nor is it possible to skip a waypoint as this can only be done on the Smartphone screen...
Is there a setting or a feature available to tell the app that there is only 1 interface available when working in CarPlay? In the old MRA Navigation app, you could control everything from the CarPlay touchscreen...
