Warning!
I recieved the VWA3B radio adapter today... and it's the wrong one!
I ordered this:

And received this:

Amazon accepted the return and paid for the shipping... so I'm only out a little time for their mistake. It appears they have the wrong picture with the accessory.
I'm going to try pluging the unit into that little metal adpater that came with the head unit. I don't expect that to work well, so I'll most likely be sending the cable back to Amazon, tomorrow.
