I have a 2012 ford focus sel. My sync system just stopped working. Only radio will work, aux, phone nothing else. I tried master reset, when I get to sync media or phone it just goes back to radio station I was last on. I took fuse out and tried car running for 15 mins, then tried leaving ignition on car off for 30 min. I then disconnected battery for 30 mins. Nothing works but radio. Tried phone with blue tooth off with aux cable and when I push aux or phone it jumps back to radio station I was last on. I've tried everything I can find online.
