iPhone and MyLink

[Mercracing]

I'm ready to go to the dealer and hopefully they will put in a new radio, or flash a computer or fix something.  I have paired my iPhone several times, turned it off and on several times and the problem persists.  The phone connects fine, and my contacts are there.  I add my favorites.  The first is my wife, her cell number.  When I go to favorites and try and call her through there, I get no name and no contact picture.  Only her number.  When I end the call the display on the radio says the call has ended, but it shows someone else's contact picture.  When I call another person on my favorites, the display shows his name but no picture.  When I end the call its the same as my wife, it shows another persons picture on the radio display.  Has anyone else had this problem?
