I have a couple of problems with the mmi which bug me. 1 With the system off and I press the nav switch the radio comes on and I have to press nav again. Same when I press the tel switch the radio comes on first. 2 with the radio on but the screen retracted into the dash, when a TP traffic bulletin come on the radio volume drops to 0. The only way to recover is the raise the screen and manually turn up the volume again. Have I just missed something in the setup or are these bugs in the software? Has anyone else found these issues?
