TMC was working up my ZT-T within the last two weeks on Friday 1st June showing roadworks, traffic queues and road closures on our way back home from Cheshire.
My ZT-T has a twin tuner radio module fitted if you do not have one of these on your car the radio will need to be tuned to Classic FM. The advantage of the twin tuner radio module is you are able to listen to any radio station or cd and still have the TMC working.
In addition to a TMC compatible disc you will need to access the setting screens for the T-info as shown below and enable the options.
The TMC icon at the bottom of the screen illuminates grey when TMC is active amd working unfortunately where we live we do not receive a very good signal for radio stations so TMC often does not work on the drive but does work when travelling somewhere. The next time we take the ZT-T out I will take a photo of TMC working.
