I have one of the Jie Rui bluetooth units being mentioned here, still connected to the HU.
It's been dead since mere weeks after I installed it and even when it was working, the quality was pretty weak
I'm planning on getting one of the BlueMusic CD changer ones (I have the same in my S60 and am very impressed with the quality) at some point
(https://www.ebay.co.uk/itm/253153228002), but €40 asking price and the lack of shipping to UK (I'll get a mate to forward it) means it's not top of my list right now.
£7.99 aux lead in the meantime for me I reckon!

At least until I get my speaker upgrade sorted later this year 8)
