I have ongoing issues with Siri Eyes Free and Phone Bluetooth on my new NX. I will connect fine and then lose the connection and Siri will not work and when you answer the phone the caller can hear me but I can't hear the caller. Hard reset of the phone fixes it for the time being. Happens randomly. I am running the latest IOS 8.1.3. Same exact phone in 2015 IS350 does not have this issue. So can't be the phone. Anyone had any Bluetooth issues with the NX?
