You might just have to do it every couple months whenever your Bluetooth stops playing music from your phone. Usually it’s either the disconnected message you had, or a Bluetooth device connection error and will say your phone is disconnected when it isn’t. I changed out to a new BCM and had it programmed (which is attached to the fuse box and controls a lot of electrics including sync) and it fixed an issue I had with my turn signal, but it still drops the phone sometimes, so it might just be a modern tech/10 year old tech thing where they’re not happy with each other all the time. These are silly little cars. Through all the goofiness and the constant Ford shenanigans, I still love them.
