I had used my voice command to instruct the Nav unit to 'Go Home' and the instruction was duly accepted. Shortly after, I received a notice to say that there was traffic congestion on the route I had selected and would I like to choose an alternative route. Using the toggle to enter NO, I pressed the 'Enter' button, several times, but there was no response. I pressed the menu button but no response, the menu function is defunct and I cannot access any of the menu facilities. The traffic congestion notice cleared after 5 minutes or so but the problem with the menu button persists. For the record, no pun intended, the DVD player is working.
Has anyone else had a similar problem?
