A couple of months ago, I was talking to my sister-in-law and she said her SYNC wasn't working, she was too busy to try to figure out how to get it fixed and didn't want to go to the dealer.
So I got her VIN number and signed her up at the SYNCMYRIDE site and downloaded the latest upgrade to SYNC for her vehicle, then sent her the jump drive. After she received the jump drive, I walked her through the steps to download the new SYNC version / upgrade.
She was so happy and now says her SYNC is working perfectly. She had never used the Traffic and Directions feature until I had explained to her the process. Now, she is a SYNC advocate too, telling everyone how much she loves her SYNC system.
I GO FURTHER as a SYNC helper!
