I have a Runner 2 watch and since the 1.7.53 software update my watch will not sync with my iphone 6. I have tried all of the usual routes, deleting the app then reloading it, resetting the watch and asking bluetooth to forget the device. At the moment when I go into 'phone' and 'pair new' the TomTom app see's the watch would then the watch disconnects before its able to pair with the phone. Any help please as it's driving me crazy!!!'.
