Transfer phone contacts on the pioneer audio system
 

So I have been having a hard time transferring any contacts onto the pioneer audio system to make calls more easily when I'm driving. I have a iPhone 4S and I follow the directions in the manual but I get stuck when the display says "transferring".

I was just curious if anyone else has run into this issue or knows something that I'm doing wrong.

Thanks in advance.

How many contacts do you have?
