The right direction pad on the steering wheel that controls the right side of the dashboard (entertainment, phone, navigation, efficiency leaves) There have been times where it acts up and not matter what button I press, up down left right enter, it enters. So when I receive a text there's no way to get back the previous menu I can only listen to the text over and over....other times it works as normal (40% of the time) My car is at 80000 kms. Please advise what I should do. Thanks
