Since there are now various SYNC version updates, and since each of your situations may be somewhat unique or different, I would suggest that you contact our SYNC Support team to help you determine your best next steps.
SYNC Software Version 2.8 was released this week as a dealer-installed update for the 2011 Ford Edge, Explorer and Lincoln MKX. The SYNC Support team can review and troubleshoot your current concern(s), and if necessary help to facilitate the dealership conversation in obtaining the SYNC update.
The SYNC Support number is 800-392-3673 (option 3), and if you have any specific questions for me feel free to reach out to me via a private message. Hope this helps!
