Happy to help. I've paddled around this pool myself a couple of times, so it's all pretty fresh. Up until last fall I had survived with the cassette adapter, but then I finally made a decision and ended up just replacing my head unit with a nice Pioneer. It has both USB and AUX inputs (the USB I ran out the back to the armrest console where there is an 8GB thumb drive) as well as built-in HD and Bluetooth. My only complaint is that it doesn't look nearly as nice as the Becker unit, but otherwise I'm thrilled with the change. Double the cost of paying Becker to add the adapter, but lots more versatility and usefulness, and fewer cables and other things strewn about.
