I've lost the ability to link my iPhone 6s to my 2014 Ultra Ltd..about a year ago it stopped working with the USB port so then I started to Bluetooth,now it won't link at all,I just had my iPhone replaced by insurance and it won't link either,not sure if anyone has had these same problems, I only use it for Pandora,I've reinstalled the App several times. I've not updated my system because that's what caused the problem originally with USB and at the time the service mgr told me to use Bluetooth instead, I replaced my battery about 6 weeks ago and it worked after that.Not sure if its an issue with settings on the phone or radio or if it needs the latest update

 

Delete and re-pair the two devices. I just had the same problem in my car. Happens from time to time.
