That's an iPhone problem. All our Androids (OnePlus, Google, Samsung, LG) have been connecting perfectly well to my TomTom navigator. Only my iPhone Xs refuses to connect. It's a well documented problem with iPhones and TomTom for many years. Similar story with my AirPods which won't connect to my Thinkpad running Linux - while all other BT headphones (Bose, Sony, Anker) do connect.
Also the article seems to primarily refer to Apple products.
