Much quicker than my old wireless carplay adapter.
Thanks to Rita in customer support this was easy to get working. Marked as 4 stars, as if the instructions in the included manual were clearer and it wasn't such small print as to be almost unreadable without a magnifying lens I might not have needed support. In the end, basically the the Bluetooth connection method was different to might old and slow wireless carplay adapter was the source of my confusion.
