What exactly is not working for you? The first post you replied to references using Apple Maps to send a location to your Tesla so I am guessing that is what you are inquiring about?
I just tested on my iPhone and the first attempt gave me a "Got to Tesla app to get started" message (or something like that). That was the first time I've seen that, but once I opened the Tesla app and then went back to Apple Maps, it worked fine (assuming the signal got to my car: I haven't gone out to check yet).
If you want some help, you have to explain what is (or isn't) happening and describe what steps you took.
Works just fine for me in both Apple Maps and Google Maps. From your comment, I assume it worked for you before. If true, are you familiar with the usual steps to deal with little gremlins like this, i.e. rebooting everything? No intention to be condescending...
