...anyone got one of these or tried them..what is the quality like , I see the ones on eBay have Bluetooth and aux in port....I like my Spotify but I like the OEM look so maybe if these are decent I will try one
Never tried them, but.... You could try the aux port hack for the head unit and get a bluetooth device (like the Kinivo BTC450, or cheaper alternative). I did that to two of my Volvo head units, crystal clear audio.
I have one connected to my HU-605. I think it's a Yatour. Actually no, IIRC it's another brand but basically exactly the same unit as a Yatour. I don't use BT as previous experience of playing music over a BT device years ago was pretty poor quality and I've never liked the idea since, although I appreciate technology has come along way since. Anyway, the little box is about the size of a packet of 20 cigs, I've wrapped it in bubble wrap and tucked it up behind the cup holder. I then have a USB lead running through a cutout in the front of the cup holder that I connect my phone to.
The yatour ones look decent. Not sure if they have bt built in though.
I've got a bluetooth adapter that works with the imiv unit very well with the HU850 unit . https://www.volvotech.eu/v70/V70-MY-2005-2008/imivbluetoothdock Have a look on there site lots of choices.
