Seems to be for later models, ie L322, but surely most aftermarket Bluetooth kits shouldn't present a fitting problem in P38s ? I had a Nokia kit fitted when I bought my P38 nearly 5 years ago and its absolutely solid, works a treat. Bought the original Nokia kit off ebay and a local auto electrical chap fitted it as the P38s electrics were a bit of a worry. Have changed phones several times since and it still works well - even had our other vehicles fitted with them as it worked so well. Also had a Smartnav system fitted which is still in use and provides a "free" incoming mobile number to you whenever you are in the car
