Robin,
This won't help you fix your problem, but it may ease the annoyance if you don't.
I've had a standard transferable Trafficmaster for years. At first I thought it was great, but with experience over 2 or 3 years I changed my mind. Not only is the constant repeating of messages, which don't actually apply to you, very annoying, but the inaccuracy of the warnings finally destroys your faith in it.
Many times I was told of long delays ahead that made me leave motorways and re-enter at the next junction only to find the traffic flowing freely, so I was the only one delayed. At other times there was no warning and I got stuck in traffic jams. Now I no longer use it. The thought that I was being messed about and paying for the privilege finally got to me.
