I have gone through the radio settings and un-checked the TP box. But after a couple of days the TP activates again and if I go into the settings the box is ticked again. The car is a E220 2015 and I am the only driver so no-one else is re-setting. Is there a way to permanently keep TP traffic setting off? Also when I play a CD and turn ignition off the CD goes back to the first track. Is this correct? other cars would keep on last track played.
