Andy, please explain; how does that play music? I gather that`s just a charger...
Your right, there are that many oprions!
I wish you could just get a block connector fit it in the back of the headunit. And a USB adaptor at the end. Simples...music; through a small memory stick, no clutter, no ipods floating around, job done.
I am swaying to the parrot idea, as that also incoporates (hands free).
As I have the flip up satnav in my car. And recently discovered a bluetooth passcode card, maybe that would solve it? Cannot find a bluetooth function on the screen or through headunit...
