I'm similarly having a problem, but can offer some add'l info:
Range Rover Sport is a 2007
BB Bold and all prior model paired perfectly
BB Torch pairs fine with our 2004 BMW
When I go thu the pairing mode, everything appears to be fine (phone sees vehicle, asks for pwd, when entered indicated paired correctly), bit it's simply not paired.
Torch is on v6.0 Bundle 1907
Not sure what to do?
