I hooked up my BTB200 bluetooth adapter this weekend and it wont allow me to register my phone. it will connect like a guest but the function button on my AVH-P4000 is greyed out in TEL mode to where i cant connect to register my phone. It will allow me to make calls but it doesnt have any options for saving or instantly connecting. I am out of ideas. I have reset my BTB unit and my head unit itself. Please help.
