apple watch series 6 with cellular

My series 6 with cellular won’t connect with my 2020 Ford Ranger’s bluetooth, the whole reason I spent so much for it was so I can leave my phone behind, I work construction so I don’t want it on site and it’s too hot to leave it in the car..I’m extremely disappointed I spent so much money on the watch and the phone but I have to listen to the radio if my phone isn’t with me, defeating the purpose, not to mention my watch didn’t receive any texts without my phone with me as well, like what’s the darn point, thinking I should switch to samsung next as I’ve heard their watches pair flawlessly with the car bluetooth without the phone
