You need to make sure you connect the cable in the correct way to the rear of the unit. It can be connected in two different ways and only one will work. I'll see if I can dig up a picture I got from the guy who provided my cable.
Hi Ken – no problem – you should have it now. I put it on 1st. recorded, instead of 2nd., recorded – that should be sufficient for delivery by Friday (it’ll leave in the morning).
Don't have a picture but here's what I was told. Hope this helps.
When you install it, the yellow connector goes to the LEFT-hand-side of the top socket behind the radio (viewed from the back), not the right-hand-side.
