Futurewise I can see the possibility of some HU manufacturers moving towards app driven platforms like android. Yes I'm aware China is doing it but I'm talking about major HU manufacturers not ebay and alibaba brands. The possibility of requiring a SIM card or something or piggybacking off of your phone's internet connection is also a possibility. Something that will take the OE market years to catch up to.
