DevonJohn....its was just that simple....
try pressinfg the TM button at the front....does it switch on the traffic master module??....if not.....(this is what was happening to me...)....then it make well be the TM as TM should work even if you havent subscribed to it!
the TM module is located in the boot, mine was above my MK4 DVD satnav drive...but some also mount it behind the CD changer.
do you have a TV module (it has a blue plug and a white plug and a FME atanae cable) ??....if so then trace the blue plug cable and it should connect to another blue plug which has two blue plugs.....one if which is connected to the TM module. So you will need to unplug the blue plug that is going to the TM and then unplug the blue plug that is going in to the TV module and plug that in to where the TM module was plugged in to.
Hope that makes some sense.......Im in Paris on business as the moment... and therefore i cannot take any photos......
I hope your problem should be just as easy!!!
let me know if you need any further info.....
