Been looking into this myself. I have a Mk2 Leon (’55 plate) with no factory hands free.
I’ve been chatting with a guy at Connects2 and they have suggested the Motorola TK30.
You get Bluetooth, USB, 3.5mm jack for connecting to it. It speaks texts, gives audio options plays music and cost less than the equivalent Parrott so far as I have seen.
I must stress I don’t own one yet but I probably will do (seen them very well priced on Amazon) so will post a review when I get round to it.
