No it should definitely be possible, I just don't think it's worth while creating a subpar and poorly-supported GPS system when phones exist. Especially when said system is forced over phones, which often happens because companies want to promote their own shit. As if their shit don't stink, when really it's the smelliest.

We don't need 1 million different applications that we have to try to integrate together. Just let me connect my messages, my GPS, my music player, even my calendar. Personally, I could give a rat's ass how fancy Tesla's interface is or GM's. It will always, always be second best to what's available on modern smartphones.
