Looking for some advice on an issue. 2018 Focus SEL no Nav. When cold unable to connect Apple device to sync 3. Also the Bluetooth will show connected but no audio passes through. 2 visit to dealer without resolution. 1) couldn’t reproduce 2) unsure if could reproduce, they updated the firmware ( to same build that was there before) and called it fixed. Spoke with service manager and they don’t have any idea. Once car is warmed up and then system is reset it will sometimes work. Any help would be appreciated.
