I have a 2 week old 2015 MCS with the standard radio / info center. Salesman paired my windows phone which worked great and stored all of my contacts. Two days ago I had the dealer installed Garmin navigation system installed. My contacts have now disappeared from car's computer. The Bluetooth still works and my call history is still on the car's computer. When I go through owner manual setup, the phone is already paired. Called dealer, they said they would address. Trying to figure out the issue myself though. I am wondering if I removed my phone from car's computer and reinstalled, if that would work. Any thoughts would be appreciated.
