Q: Iphone 6 plus can't connect via Bluetooth

Hello,

I have a 6+ and am having issues with bluetooth.   When I try to connect it to my Jeep Grand Cherokee it will do so but for only a second or so and then drop.  I juat tried to pair the same phone to my mac book pro and the same thing happens.   I see all the instructions ane codes on both devices and when I try to pair the phone and my computer it wont do so.  I have updated my phone and computer to the latest software versions and confirmed bluetooth Is on etc etc.    Any help is greatly appreciated.  Thanks, Joe
