Hi all, I have 63 plate Sportback, with the MMI Radio. When its on DAB, the station changes from Radio 4 (Please don't judge!!) to Heart Norfolk. It appears to happen within a couple of minutes of getting into the car, and also at specific places that I drive through (for instance at the end of my road, near a certain roundabout and also when I leave my workplace). This leads me to believe that its a signalling problem rather than a problem with the radio itself. Dealer has checked and says that they have no other reports of the problem on file, and that the MMI has latest updates. I know its not a huge problem but its very annoying, especially as the Heart Norfolk channel seems to a be about 6000 decibels louder than Radio 4. I have tried a rescan but problem still happens. Had the car from new and problem started about 6 months ago. Anybody else experience this?
