Sync 3.4 is a welcome addition for the Ford Sync system. Sync system is the infotainment for Ford vehicles such as Ford F150 and Ford Mustang. I upgraded to Sync 3.4 recently on my Mustang GT.

Sync 3.4 has been really great to me especially with the new user interface and overall a much faster system. However, recently my sync 3.4 experienced this weird glitch on my 2019 Mustang GT.

I was able to resolve this Sync 3.4 issue. The problem went away after I restarted the Sync system on my 2019 Mustang GT.
