I fitted a low cost plug and play bluetooth adaptor a few moths ago and it has been really good . Cost was 39 euros inc postage directly from Germany. Connects via the cd multiplayer plug and you have to find an earth which I did jamming the ring crimp under one of the radio casing clips. To use select the cd multiplayer , and the ff button to take calls , to make calls use siri voice command on your phone . Good phone quality unlike the cigarette lighter plug in adaptor I had been using.
Has worked without any problem other that once had low volume . I unpaired and repaired and it was fine no re-occurrance
Good VFM and easy fit ....anyone else got this?.
