First of all, thank you for everyone who pointed out that the car has an owner's manual. At least none of you used the usual RTFM which is so prevalent elsewhere on these forums. But of course, if you go back and read my original post, you will see that the issues I raised are not covered in the manual, which I of course, read before I made the post.
After the kind replies from the rest of you, with all due respect, I'm still left with my original questions.
1) How am I streaming if I never logged into anything, because I keep finding a "streaming" page which has a login at the bottom which I never used.
2) Why am I able to search for, and pull up distant radio stations which appear to come from a service called "Tuned In" , but I never logged into or subscribed to that either?
3) Why does that service find some stations I'm listening to, including their logos (WCBS New York, WINS New York), but when I listen to the stations, what I get are in reality Canadian stations on the same frequency?
4) And why can't "recents" be deleted, leaving you with a string of clutter?
Please understand, I love my car, I'm sold on Tesla, and I'm totally on board with being a part of this wonderful family and ecosystem. But in any wonderful family, it's ok to talk after he leaves the house about the crazy uncle who bores everyone with stories about his Hawaiian vacation. In other words it's ok not to like the entertainment interface, to not even understand it, and to point out that it needs to be fixed. And that doesn't mean I'm somehow a traitor to the cause.
Thank you.
And yes, it should have been explained in the owner's manual. But it wasn't. And that's one more thing that should be fixed.
