I am after some advice on this as i have no idea now what to do. I have retro fitted the bluetooth phone kit to my s4 and programmed it so that the phone comes up on the screen and can make calls etc. Now the problem is it will not let me add my phonebook or contacts and when i put the computer on and try and go into telephone it just say to many communication errors can not connect so i can not do anything to the bluetooth kit. Does anyone know what i am doing wrong or what i need to do to fix this as i am stuck now. Thanks for any advice on this.
