I have this fitted to my car, but I no longer subscribe to the service which I got for free from new for many years.
I find the Traffic Live service now offered by TomTom is cheaper and better, for me at least.
Speed warnings and mobile vans as are moved, traffic info updates keeping fastest routes to where you are going, where hold ups are building, alternate routes and much more, also available on your iPhone to.
The original system is fitted into interior light display with the mics fitted where the holes are if you have this unit without fitment.
"My lovely car now sold onto a very happy new owner.
I still love this marque and I will still be around, preferred selling to breaking, as a great runner and performer"
