Works excellently in my Mk 3 with Bose system, However, no fitting or operation instructions came with the unit. Thanks to other reviews and web searches I fitted the multi plug by removing the radio unit (pry side panels and remove 2 screws). Operating instructions were by trial and error and web search again (using the 1 & 2 programme buttons to scroll between the Bluetooth and Aux - in wasn't intuitive. Instructions really should be provided hence 3 stars. It would be 5 stars for sales, service and the product otherwise.
