DiCE Unit and Yatour Hi-Fi Decoder
 

I've cross posted these items from the S40/V40 sales section because I guess they may have wider appeal - can be collected from central Lincoln, or I can post/courier at cost.

Clone DiCE unit
Good quality unit, was compatible with my diesel S40 - no software included, you will have to source this yourself. £50 + postage

Yatour Hi-Fi decoder with Bluetooth
Plugs into the back of your Volvo HU or SC Head Unit and allows you to play music from USB, SD Card or Bluetooth - also works (surprisingly well) as a hands free kit - plugs into the CD changer socket on your HU and requires one wire connecting to a live 12V source - comes boxed with instructions.
I only ever used this via bluetooth, so tucked all the gubbins away behind the stereo for an invisible (apart from the microphone) install. £40 + postage
