If the TMC is green then it's all setup and working.

When not being routed, (ie normal driving) then you get a list of traffic delays and details in the Traffic menu, and the warning on screen, but it won't offer automatic re-routes (unless you have the dynamic bm54 from setp 05 onwards).

When being routed however, then the TMC comes in and alerts you (by voice and display) and will offer you the option of going round or finding another route.

You normally only get TMC messages when there is a problem, not for all roadworks, (where traffic is moving as normal).

Also the cd/dvd must be TMC compliant (if the TMC is green then it is).
