Hi guys. I have a 2014 Fiesta with the original version of Sync that looks like the image below. My iPhone 7 works really well with it over Bluetooth, but I prefer using USB as the audio quality is better, it's louder, and shows song info on the car display. USB keeps disconnecting, causing the phone to switch to Bluetooth. I then have to switch the stereo over to bluetooth. If I try to go back to USB it doesn't see the phone. Sometimes it lasts a few songs before it disconnects. I can't tell whether it's a physical connection issue as it sometimes does it after going over bumps etc. Weirdly it kept doing it persistently when approaching the Blackwall Tunnel. Any ideas? I'm taking the car in for a service at Ford this week so will ask them, but I imagine they'll charge me £75 for nothing and won't be able to replicate the problem. I've checked the Ford website and it says my firmware is up-to-date. Cheers in advance.
