I think what you're missing is that Nav, Trip Planner, Media Player (not MP3 player) has been broken for years. The first two are essential driving aids so those of us who have owned the car for a while are baffled by why it would take years to fix those things despite repeated promises. AP is fine but it's not as important to me as getting accurate directions to my destination or knowing which SuperChargers to stop at on my road trip.
Can you clarify the broken part of nav? I drive roughly 140miles a day. Done a couple 1500+ road trips and the Nav hasn't gotten me stranded yet. It should be routing you through super chargers based on your destination.
If you aren't getting the routing through superchargers you may have something turned off or might need to see why your car is not routing you correctly.
I do agree however that AP shouldn't be the only thing but everyone is pre judging let's wait for it to come out before making assumptions on what else is being or not being updated.
