Okay, this was gratifying to read, but ... can't you wedge CarPlay onto this thing? I'd want a victory lap with root doing at least something. Bad apple on car boot, there's lots of options here!

Yeah, I'll keep working on this to get it to do more stuff that's at least a little bit more useful, if not just a better UI that isn't 90% a useless "No maps found" screen. It's more complicated than it might initially seem because they actually have a kernel module blocking me from mounting non-signed partitions as exec, so I'll need to work around that.

I'll probably post a follow up if I get anywhere with this!
