I changed a phone number on my iphone but the old phone number shows up on the navigation display. Anyone know how to change this? I have looked it up in the book and on all menu options, as far as I know, and cannot find an edit phone number anywhere. So, when I call the number, the nav system dials the old number that is displayed. I have to tell siri to call the name and then it works. Your help is greatly appreciated.

 

Unpair it and pair it again.
