Context: I’m not an app developer, but I’m doing some research in order to gain a high level understanding of an app that I want some developers to build for me.
Basically I need a navigation app built (integrated with Google Maps) that works pretty much like Google Maps. This app will connect to and stream live navigation data to a car HUD (heads-up-display) device using WiFi direct (to facilitate high bandwidth streaming). The purpose of the streaming from the mobile app to the HUD is so that the driver can see the live map without having to look at their phone.
This leads me to my QUESTION: this functionality (streaming from app to HUD) is similar to what AirPlay does & I’ve read that Apple rejects apps that replicate AirPlay’s screen mirroring function. I’ve also read that in order to work around this, my app should limit the information that is sent to & displayed by the HUD device (basically, shouldn’t mirror the whole screen). So, would Apple still reject my app if it only streamed the live map onto the HUD device & left out all the other information displayed on the app (ETA, turn signals, distances etc.) and thus refraining from streaming the entire screen?
