Paul has updated his request for information.
Brock,
The cable I seek is for my Honda ST1300 Pan European. It has the Pioneer head unit as mentioned, but no CD player.
By using a digital CD changer, (in this case a Yatour) one can play one's own music through the ST1300's system.
Again may I ask if anyone has such a cable they wish to sell.
Most people would have gone to blue tooth and may not have need of this approach.
I too have gone blue tooth, but having the radio and the handle bar controls there, I thought why not hook up a CD player...but not enough room.
On doing some research I discovered that a digital 'CD Changer' could be used after simply downloading one's choice of music onto a thumb drive.
I hope this clears the air, and again I assumed it was something that had presented itself before, hence the lack of detail on my part.
Many thanks, Paul S
